Quality and Readability of Online Information on In-Office Vocal Fold Injections
Authors: Yi Grace S. , Hu Amanda 
Published: November 2019

Objectives:Vocal fold injection augmentations are increasingly being performed in the office setting on awake patients, as opposed to the operating room. These procedures thus require patient cooperation and education. As the Internet is a widely-used resource for patients, our aim was to assess the quality and readability of online resources on in-office awake vocal fold injections.Methods:An online Google search using the terms “office vocal fold injection medialization” and “awake vocal fold injection” was conducted. The first 50 English-language websites were categorized into professional- and patient-targeted, and major and minor sources. They were analyzed using the Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL) test, and DISCERN quality score.Results:Fifty websites were evaluated, and the overall DISCERN score was 2.60 ± 1.01, the mean FRES was 32.16 ± 19.10, and the mean FKGL was 13.76 ± 4.12. Between the 25 professional-targeted and 25 patient-targeted websites, professional-targeted sites had significantly higher DISCERN ( P < .05) and FKGL ( P < .05) scores, and lower FRES ( P < .05) scores. Between the 30 major and 20 minor websites, major websites had significantly lower FRES ( P < .05) and higher FKGL ( P < .05) scores, and there was a trend toward significance for higher DISCERN scores ( P = .052).Conclusions:Our study shows that half of the top Google results for our topic were not written for patient education, but rather for health care professionals. The reading level of this information exceeds the recommended grade level for patient education materials, and may be less comprehensible than intended. While patient-targeted materials are easier to read than professional-targeted sites, they are of lower quality. The quality of the available online information on this topic is suboptimal for both patients and health care providers. This research highlights the need for more appropriate patient education materials given low health literacy rates.

Background Primary epithelial ovarian cancer is divided into several subtypes. The relationships between apparent diffusion coefficient (ADC) values and their subtypes have not yet been established. Purpose To investigate whether ADC values of epithelial ovarian cancer vary according to histologic tumor cellularity and evaluate the difference of clear cell carcinoma (CCC), high-grade serous carcinoma (HGSC), and endometrioid carcinoma (EC). Material and Methods This retrospective study included 51 cases of epithelial ovarian cancer (17 CCC, 20 HGSC, and 14 EC) identified by magnetic resonance imaging with pathological confirmation. All patients underwent diffusion-weighted imaging and the ADC values of lesions were measured. We counted the tumor cells in three high-power fields and calculated the average for each case. The Spearman’s correlation coefficient test was used to analyze correlation between ADC values and tumor cellularity. The ADC values of HGSC, EC, and CCC were compared using the Steel–Dwass test. Results The ADC values of all cases were significantly inversely correlated with tumor cellularity ( rs = −0.761; P < 0.001). The mean ± SD ADC values (×10−3 mm2/s) of CCC, HGSC, and EC were 1.24 ± 0.17 (range 0.98--1.65), 0.84 ± 0.10 (range 0.67--1.06), and 0.84 ± 0.10 (range 0.67--1.07). The mean ± SD tumor cellularity of CCC, HGSC, and EC was 162.88 ± 63.28 (range 90.33--305.67), 440.60 ± 119.86 (range 204.67--655.67), and 461.02 ± 81.86 (range 333.33--602.33). Conclusion There is a significant inverse correlation between ADC values and tumor cellularity in epithelial ovarian cancer. The mean ADC value of CCC was higher than those of HGSC and EC, seemingly due to the low cellularity of CCC.

Published: November 2019

Background Appropriate mammary positioning is an important factor in optimizing image quality in mammography (MMG). Purpose To study the correlation of quality criteria and breast density classification proposed by the American College of Radiology (ACR) and European Guidelines and its influence to achieve a proper positioning, therefore an adequate MMG. Material and methods A total of 128 routine MMG examinations were reviewed for the definition of breast composition parenchyma and assessment of several quality criteria proposed by the ACR and European Guidelines to achieve an adequate MMG. Adequate MMG was defined as a difference between the posterior nipple line (PNL), difference of the mediolateral oblique (MLO) and craniocaudal (CC) incidences > 1 cm. The quality criteria were analyzed as a function of correlation coefficient in order to evaluate the individual impact of each factor and analysis of variance (ANOVA) for all criteria. Receiver operating characteristic (ROC) curves were plotted to evaluate the performance of the criteria on each type of parenchyma. Results Negative correlation of fatty breasts and visibility of the mammary angle, a greater number of skin folds and PNL > 1 cm (r < 0). Dense MMG presented less visibility of the lateral tissue compared with other categories. Area under the curve of ROC analysis revealed values of 53.1% and 54.7% for the right and left breasts, respectively. Conclusion Several factors influenced in the MMG process, but we find that breast parenchyma has a substantial role in affecting these criteria and therefore a correct position for diagnosis, which could compromise MMG diagnostic performance.

Published: November 2019

Background Stenotrophomonas maltophilia ( S. maltophilia) is a globally emerging, rare, waterborne, aerobic, gram-negative, multiple-drug-resistant organism, most commonly associated with respiratory tract infection in humans. Computed tomography (CT) findings in patients with S. maltophilia pneumonia are rarely reported. Purpose To compare CT findings between immunocompromised and immunocompetent patients, and to determine characteristic imaging findings of S. maltophilia pneumonia. Material and Methods CT findings of eight immunocompromised and 29 immunocompetent patients with proven S. maltophilia pneumonia were reviewed retrospectively. Different patterns of CT abnormalities between immunocompromised and immunocompetent patients were compared by Fisher’s exact test. Results Patchy ground-glass opacities (GGOs) were the most common CT findings, present in 36 (97.3%) of the 37 patients. Among the patients with patchy GGOs, consolidation was seen in 29 (78.4%) patients, and centrilobular nodules were noted in 15 (40.5%) patients. The transaxial distribution of the parenchymal abnormalities was predominantly randomly distributed in 30 (81.1%) cases. Regarding longitudinal plane involvement, the predominant zonal distributions were the diffuse distribution (n=23, 62.2%) and the lower lung zone (n=14, 37.8%). None of the patients showed upper lung zone predominance. The proportion of patients with parenchymal CT findings or associated findings in the immunocompromised patients was not significantly different from that of the immunocompetent patients. However, lower lung zone predominance on the longitudinal plane was significantly more common in immunocompetent patients than in immunocompromised patients (14/29 vs. 0/8, P=0.015). And diffuse distribution of parenchymal abnormalities on a longitudinal plane was significantly more frequent in immunocompromised patients than in immunocompetent patients (8/8 vs. 15/29, P=0.015). Conclusion The most common CT patterns of S. maltophilia pneumonia in immunocompromised and immunocompetent patients were patchy GGOs and consolidation. However, in immunocompetent patients, parenchymal abnormalities were more predominately distributed in lower lung zone than in immunocompromised patients; and in immunocompromised patients, parenchymal abnormalities were more diffusely distributed than in immunocompetent patients.

Objective To compare the test-retest reliability and validity of three simple maximal isometric back extensor strength (BES) assessment protocols with different test postures, and to recommend an optimal clinical protocol to quantify BES. Methods Asymptomatic adults, aged over 45 years, were assessed for maximal isometric BES using external fixation of dynamometers, with the subject in standing, prone and sitting positions, respectively. Measurements were repeated at a one-week interval to examine test-retest reliability. Validation was performed by comparing with results obtained from isokinetic dynamometer assessments. Results Out of a total of 60 included participants, intra-class correlation coefficients (ICC) were 0.92, 0.93 and 0.90 in standing, prone and sitting positions, respectively. Correlation analyses revealed acceptable convergent validity in the standing and prone position (r = 0.50 and 0.54, respectively), whereas tests conducted in the sitting position showed a relatively low validity (r = 0.32). Among the three protocols, measurement error was lowest in the prone position. Conclusions Maximal isometric BES assessment in the prone position was shown to be the most reliable and valid protocol, and may be considered the preferred option for assessing BES in clinical practice.
Buprenorphine for Cancer Pain in Patients With Nonmedical Opioid Use: A Retrospective Study at a Comprehensive Cancer Center
Authors: Hansen Eric , Nadagoundla Chitra , Wang Chong , Miller Austin , Case Amy Allen 
Published: November 2019

Background: Outpatients with cancer commonly have nonmedical opioid use (NMOU) behaviors and use opioids to dull emotional and existential suffering. Buprenorphine is often used for cancer pain due to less reported euphoria when compared to other opioids. Methods: A retrospective review was done in patients who were prescribed buprenorphine for cancer pain. Pain scores were reported on a Likert pain scale of 1 to 10. Nonmedical opioid use was defined as patients taking opioids for emotional pain at or above the maximum prescribed amount. Results: For 16 patients, the mean pain score prior to buprenorphine (pain pre) was 8.3 (Standard deviation (Std) 1.6), and the mean pain score on follow-up post-buprenorphine (pain post) was 6.1 (Std 2.3) with a reduction in mean pain score (pain change) of −2.0 (Std 2.9, P = .059). Those patients without NMOU had a pain prescore of 9.5 (Std 1.0) and pain post of 4.3 (Std 2.5) with a mean pain change of −5.0 (Std 1.7, P = .20). The mean pain change in those with chemical coping (−1.3/Std 2.7), illicit drug use (−2.8/Std 1.0), or psychiatric comorbidity (−2.4/Std 2.7) were reduced after buprenorphine, however, not statistically significant. Outpatient rotation to buprenorphine was well tolerated. Conclusions: The pain score in those patients without NMOU was significantly lower after rotation to buprenorphine than those with NMOU. We deduce that in those with NMOU, it is more challenging to achieve pain relief with buprenorphine. Overall, for all patients, rotation to buprenorphine resulted in a marginally significantly reduced pain score.

Published: November 2019

Background: Palliative care consultation during serious life-limiting illness can reduce symptom burden and improve quality of care. However, quantifying the impact of palliative care is hindered by the limitations of manual chart review and administrative coding. Objectives: Using novel natural language process (NLP) techniques, we examined associations between palliative care consultations and performance on nationally endorsed metrics for high-quality end-of-life (EOL) care in patients with leptomeningeal disease (LMD) secondary to metastatic breast cancer. Methods: Patients with breast cancer with LMD were identified using administrative billing codes and NLP review of magnetic resonance imaging reports at 2 tertiary care centers between 2010 and 2016. Next, NLP was used to review clinical notes to (1) determine the presence of palliative care consultations and (2) determine the performance of process measures associated with high-quality EOL care, including discussions of goals of care, code status limitations, and hospice. Associations between palliative care consultation and documentation of EOL process measures were assessed using logistic regression. Results: We identified 183 cases of LMD. Median age was 56 (interquartile range [IQR]: 46-64) years and median survival was 150 days (IQR: 67-350). Within 6 months of diagnosis, 88.5% of patients had documentation of ≥1 process measure, including discussions of goals of care (63.4%), code status limitations (62.8%), or hospice (72.1%). Palliative care consultation was a predictor of subsequent documentation of goals of care (odds ratio [OR], 3.15; 95% confidence interval [CI], 1.58-6.27) and hospice discussions (OR, 4.61; 95% CI, 2.12-10.03). Conclusion: Palliative care involvement is associated with increased performance of EOL process measures in patients with breast cancer with LMD.

Authors: Yüksel Mavişe , Basım Pelin 
Published: November 2019

BackgroundThe literature contains conflicting reports on the epidemiology and frequency of hidradenitis suppurativa (HS), a chronic, recurrent inflammatory disease of the apocrine glands.ObjectiveTo evaluate the clinical and demographic characteristics of HS cases in Turkey and investigate the similarities with world epidemiology.MethodThe records of 208 patients that presented to our polyclinics and were diagnosed with HS between June 2012 and July 2017 were retrospectively evaluated.ResultsOf the cases, 68.3% were male and 31.7% were female. Of the patients, 75.5% had no family history of HS, 60.6% were smokers, 39.4% were aged 20-29 years, and 36.1% were aged 30-39 years. The most commonly involved regions were the axilla (62%), groin (50.5%), and gluteus (15.9%). According to univariate analyses, male patients had higher disease stages than females (odds ratio=1.67). The patients with groin involvement, high body mass index (BMI), and low education level (0-8 years) had higher risk of severe disease stage (odds ratio=1.63, 8.91, and 1.51, respectively). The most commonly used treatment was oral antibiotics in Hurley stages I and II, and surgical intervention in Hurley III. In all 3 Hurley stages, clavulanic acid–amoxicillin combination was the mostly used systemic antibiotic (41.8%, 43.2%, and 47.8%, respectively).ConclusionsThis is the first epidemiological study on HS in the Turkish population, where HS shows male predominance. Male gender, low education level, absence of acne, high BMI, and groin involvement were associated with severe disease stages. Determining associated comorbidities and possible risk factors is important in progression and prevention of the disease.
Utility of erythrocyte indices in identifying iron depletion in pregnancy
Authors: Vora Sona M , Messina Gianfranco , Pavord Sue 
Published: November 2019

Background Iron deficiency anaemia in pregnancy is common and is a major cause of maternal and neonatal morbidity worldwide. Serum ferritin is the current gold standard test for identifying iron depletion, with a cut-off value of 30 µg/L. Recent studies in low- and middle-income countries have identified mean cell haemoglobin concentration as a surrogate marker for the prediction of iron depletion. Methods We studied values from 786 antenatal blood results from 2018 in Oxford, UK, and correlated the red cell indices with serum ferritin measurements. Results Haemoglobin, mean cell volume, mean cell haemoglobin and mean cell haemoglobin concentration have low specificity and sensitivity for the identification of iron depletion. Conclusions We found that haemoglobin, mean cell volume, mean cell haemoglobin and mean cell haemoglobin concentration do not have sufficient predictive value in this population to be used as a screening test for non-anaemic iron depletion.
The role of internet resources in health decision-making: a qualitative study
Authors: Bussey Lauren Georgia , Sillence Elizabeth 
Published: November 2019

Objective Internet resources remain important for health information and advice but their specific role in decision-making is understudied, often assumed and remains unclear. In this article, we examine the different ways in which internet resources play a role in health decision-making within the context of distributed decision-making. Methods We conducted semi-structured interviews with 37 people in the United Kingdom who reported using the internet in relation to decision-making, and representing a range of long- and short-term health conditions. The interviews focused on decision-making activities across different settings and in relation to different stakeholders to understand how internet resources play a role in these activities. We carried out a thematic analysis of the interviews. Results We identified three main ways in which internet resources played a role in health decision-making. A supportive role (as a decision crutch), a stimulating role (as a decision initiator), and an interactional role (impacting on the doctor–patient relationship). These three roles spanned different resources and illustrated how the decision-making process can be impacted by the encounters people have with technology – specifically internet based health resources – in different ways and at different time points. Conclusions Examining health decisions with respect to internet resources highlights the complex and distributed nature of decision-making alongside the complexity of online health information sourcing. We discuss the role of internet resources in relation to the increasing importance of online personal experiences and their relevance within shared decision-making.

Published: November 2019

Background: A Konno operation with a mechanical prosthesis may be applied in patients with complex left ventricular outflow tract obstruction to avoid further operations. We reviewed our 20-year experience with the Konno operation. Methods: All patients who underwent the Konno operation between 1996 and 2015 were evaluated. Study end points were survival and reoperations. Results: Twenty-one consecutive patients were included. The median age at operation was 12 years (5 months to 34 years). Twenty (95%) patients had prior interventions for left-sided heart lesions. Additional mitral valve disease was present in 17 (81%) patients. The preoperative mean pressure gradient over the left ventricular outflow tract was 50 ± 25 mm Hg. The median size of implanted valve prostheses was 21 mm (16-25 mm). Concomitant procedures for left-sided heart lesions were performed in six patients, including two mitral valve replacements. There were two hospital mortalities (9.5%) and four late mortalities (19%). Overall survival was 85% ± 7.8% and 72% ± 11% at 5 and 10 years, respectively. In two patients, mitral valve replacement was performed during the same hospital admission. During a mean follow-up time of 7.6 ± 4.8 years, two patients required late reoperations, one for mitral valve replacement and one for heart transplantation. Freedom from late reoperation at 10 years was 89% ± 7.4%. Conclusions: The Konno operation can be considered as a definitive option with a low probability of reoperation on the left ventricular outflow tract in patients with complex left ventricular heart disease. Subsequent operations focus on the treatment of additional mitral valve disease, which remains the cause of mortality and morbidity.

Published: November 2019

Introduction: Interpretation of risk by parents of children undergoing congenital cardiac surgery is poorly documented. The available evidence highlights a dichotomy where clinicians suggest parents may not grasp the complexity and risk associated with procedures, while some parents suggest risk is unnecessarily overemphasized. Aim: To quantify how risk is perceived by parents. Methods: One hundred six parents of children undergoing cardiac surgery were recruited and completed a Likert-type scale from 1 (perceived low risk) to 6 (perceived high risk), at 5 points: arrival at preadmission, post discussion with anethetist/surgeon, day of surgery, discharge from intensive care, and at outpatient follow-up. The surgical sample was stratified according to Risk Adjustment in Congenital Heart Surgery level. Analysis: Data were analyzed using Wilcoxon rank tests for differences in distributions of scores and Krippendorff α to examine the level of agreement. Results: Median parental risk scores varied over time, with no consistent risk scores observed. Maternal scores were consistently higher than paternal scores at every time point ( P < .001). Postoperative complications resulted in a persistent rise in risk perception at follow-up ( P < .001). Analysis of parental risk scores and objective measures of surgical risk highlighted poor agreement that was particularly marked at the extremes of risk. Conclusions: Parents perceived higher risk scores than those reported by the clinical team. Mothers reported statistically significantly higher scores than their partners, highlighting potential tensions. In addition, the changing perception of risk over time emphasizes the need for flexible levels of support and information as parents navigate uncertainty.
