Abstract
Abstract
Purpose
To assess the effectiveness of Buteyko breathing technique in patients with obstructive Eustachian tube dysfunction (ETD).

Materials and methods
Fifty-one patients (77 ears) aged between 21 and 62 years were randomized to Buteyko breathing in conjunction with medical management (nasal steroid) group or medical management alone group. The Eustachian Tube Dysfunction Questionnaire (ETDQ-7) symptom scores, tympanogram, positive Valsalva maneuver were evaluated at baseline, 6-week and 12-week follow-up.

Results
Normalization of ETDQ-7 symptom scores at 6-week follow-up was observed in 30.0% (12/40) of the Buteyko breathing group versus 16.2% (6/37) of the controls (P > 0.05). At 12-week follow-up, the ratio rose to 50.0% (20/40) in the Buteyko breathing group and 24.3% (9/37) in the controls (P < 0.05). Tympanogram normalization at 12-week follow-up was observed in 53.6% (15/28) of the Buteyko breathing group versus 26.9% (7/26) of the controls (P < 0.05). The Buteyko breathing group showed slight improvement in positive Valsalva maneuver at 6- and 12-week follow-up (P > 0.05).

Conclusions
Our study shows that Buteyko breathing technique might be an effective adjunctive intervention in treatment of obstructive ETD, especially for those patients who are refractory to medical treatment and cannot afford Eustachian tube balloon dilation surgery.

Abstract
Abstract
Purpose
To determine the epidemiology and survival of primary conjunctival malignant neoplasms.

Methods
Retrospective analysis of primary malignant conjunctival neoplasms using Surveillance, Epidemiology, and End Results database from 1973 to 2012.

Results
Of 1661 cases, the most common neoplasms are squamous cell carcinoma (SCC) at 54.8% and melanoma at 38.8%. Mean diagnostic age for melanoma was 62.1 compared to 65.5 years for SCC (p = 0.002). 52.2% of melanoma are male versus 77.4% of SCC (p < 0.001). For SCC only age (HR: 1.09, 95% CI:1.04–1.14) is a predictor of survival. For melanoma, age (HR: 1.07, 95% CI: 1.05–1.10), male sex (HR: 2.04, 95% CI: 1.16–3.60), T4 tumors (HR: 3.38, 95% CI: 1.17–9.80) and N1 status (HR: 8.69, 95% CI: 2.75–27.42) are all survival predictors. The 5 and 10-year overall survival (OS) estimates are not significantly different between SCC and melanoma, with 70% and 50% respectively for SCC, and 71% and 50% respectively for melanoma. Median survival time is worse for blacks (52 months) compared to whites (118 months) and Asians/Native Americans/Pacific Islanders (145 months), however race was not found to be a significant prognostic factor in multivariate analysis. Five-year survival are similar between decades 1973–1982 (66.2%), 1983–1992 (69.2%), 1993–2002 (71.3%) and 2003–2012 (70.2%).

Conclusion
Age at diagnosis is a determinant of survival for both conjunctival SCC and melanoma. Male sex, T4 and N1 staging are also important prognostic factors for melanoma. With respect to overall survival, SCC and melanoma did not differ significantly.

Abstract
Abstract
Objectives
To investigate the relationship between barometric pressure and the incidence of benign paroxysmal positional vertigo (BPPV).

Methods
181 patients diagnosed with classic BPPV seen between 2011 and 2016 were identified. Demographic information, data of onset, and date of presentation were recorded. Historical barometric data for each of the 60 months were recorded. In addition, monthly counts of other atmospheric, infectious, and allergic variables for that time period were recorded. Correlation analysis compared monthly incidence of BPPV with absolute and relative changes in atmospheric conditions.

Results
The incidence of BPPV onset demonstrated a statistically significant positive correlation with barometric pressure, where every one-unit increase in barometric pressure leads to an expected increase of 6.1 diagnoses (p = 0.0008). The correlation coefficient (r) between barometric pressure and BPPV diagnoses was 0.66 (95% CI 0.14–0.90) with a p-value of 0.0131. Other seasonal variables demonstrated correlation, though none as strong as barometric pressure.

Conclusions
Barometric pressure has been long been associated with conditions of the inner ear, though its relationship to the pathogenesis of BPPV has not been investigated. Monthly changes in barometric pressure, rather than the absolute value, may be responsible for the observed changes in incidence. These findings demonstrate a clear association between barometric pressure and BPPV that may help to explain both the etiology of BPPV and its possible connection to migraine-related conditions.

Abstract
Abstract
Purpose
To determine the thermal energy damage potential by heat sources, such as endoscopes and fiber optic light cables, in contact with materials commonly placed around an operating room (OR) table.

Materials and method
Injury by xenon and halogen light sources were tested by direct and indirect contact using fiber optic light bundle cables and scopes at light intensities between ranging from Standby to 100%. The scopes had diameters ranging from 2.7 mm to 10 mm and were set at varying angles. The materials tested were surgical drapes, cotton towels, child shirts, child pants, lap sponges, X-ray detectable sponges, and Mayo covers. The damage potential was determined qualitatively by presence of smoking or smell of burning.

Results
Permutations involving direct contact were able to cause thermal injury, while permutations involving indirect contact, endoscopes, or halogen lamp were not. The xenon light source with the fiber optic light cable created thermal injury at light intensities of 50%, 75%, and 100%. Time to injury increased as light intensity was decreased. Only the surgical drape, child shorts, and cotton towel showed evidence of burn injury.

Conclusions
This report supports the potential for thermal injury to the patient secondary to fiber optic light sources, although this potential may be limited in extent. The injury risk can be reduced by avoiding direct contact to materials overlying the patient, confirming standby mode or 25% light intensity, and maintaining the endoscope connected to the fiber optic cable at all times.

Abstract
Abstract
Objectives
A three-dimensional inversion-recovery sequence with real reconstruction (3D-real IR) sequence 4 h after intravenous gadolinium injection (IV) has been used to visualize the endolymphatic hydrops (ELH) in Meniere's disease (MD). This study was designed to explore the pathology of MD with partial ELH.

Methods
We collected 338 patients with definite MD, all of whom underwent the IV method. Patients who were found to have partial ELH (vestibular or cochlear) were enrolled. The hearing thresholds of the enrolled patients were analyzed, the regions of interest of the cochlear perilymph and the cerebellum white matter were determined, and the signal intensity ratio in the former to the latter (CC ratio) for both sides in the patients was subsequently evaluated.

Results
Of the 338 collected patients with definite MD, 19 patients (5.6%) had unilateral vestibular ELH (N = 18) or cochlear ELH (N = 1), and 4 patients (1.2%) with bilateral ELH had contralateral cochlear ELH. The CC ratio of the affected side (1.44 ± 0.46) was higher than that of the unaffected side (1.15 ± 0.33, P < 0.05) in the 19 patients with unilateral ELH. Conversely, there was no difference between the ratio of the contralateral side (1.18 ± 0.16) and the unaffected side (P > 0.05) in the 4 patients with bilateral ELH.

Conclusions
Partial vestibular ELH was more common than partial cochlear ELH in MD. Moreover, vestibular ELH, rather than cochlear ELH, may correlate with the elevated contrast effect in the affected side, which may better reflect the pathologic mechanism of MD.

Abstract
Abstract
Plunging ranulas are most often treated surgically; various surgical approaches may be necessary depending on the unique characteristics of each case. Here, we present the case of a plunging ranula noted on imaging to have a cordlike tether, which was revealed intraoperatively to be the lingual nerve. This case illustrates the importance of preoperative imaging for surgical planning, and when a transcervical approach may be the best choice for plunging ranulas.

Abstract
Abstract
Purpose
This prospective cohort study was completed to evaluate a systematic approach for teaching nasal analysis to otolaryngology-head and neck surgery residents.

Methods
Residents from each post graduate year (PGY) were randomized to the control group or study group. Residents in the study group were given a 10-slide PowerPoint (Microsoft Corp) instruction on nasal analysis using the standard sequence of photographs and anatomic elements to describe in each view. All residents were given the standard sequence of photographs of 3 patients for assessment on nasal analysis. Then 12–14 weeks later all residents were re-evaluated using photographs of 3 new patients. The results were blinded and graded using an 18 point scale modified from a previous publication [1].

Results
Twenty otolaryngology-head and neck surgery residents completed the study. Analysis was performed with and without multivariate regression modeling to adjust for PGY, gender, and number of rhinoplasties performed. The study group had overall higher scores in both the initial and follow up assessment, specifically with subsite-specific dorsal deviation, tip projection, and nostril symmetry. Neither group obtained high scores in facial symmetry, skin thickness, tip shape and contour, and radix position at initial or re-assessment.

Conclusion
Nasal analysis is a complex task. A lecture on a systemic approach to facial analysis given to a group of residents, who performed significantly better on facial analysis cases than controls. Further research in providing feedback, periods of rehearsal or testing, or focused selected elements with serial exposure can be considered.

Abstract
Abstract
Background
Since most HPV-associated disease occurs in the tonsillar-related areas (TRA) – palatine and lingual tonsils, the effect of HPV on survival in non-tonsillar oropharyngeal subsites (nTRA) is not well established. The objective of this study was to use a large population-based cohort to investigate the survival impact of HPV in nTRA subsites versus TRA subsites.

Methods
This SEER database study was conducted by stratifying the HPV-positive oropharyngeal cancer cohort into two primary groups, TRA and nTRA.

Results
HPV-positive squamous cell cancer was significantly more common in TRAs (73%) compared to nTRAs (31.2%, p < 0.001). After controlling for age, treatment, stage, race, and income, patients with HPV-positive disease in nTRAs had a worse cause-specific survival (CSS) than individuals with HPV-positive disease in TRAs (HR = 2.16, 95% CI 1.20–3.86, p = 0.01).

Conclusion
Patients with HPV-positive OPSCC in nTRAs had poorer survival outcomes compared to patients with HPV-positive OPSCC in TRAs.

Abstract
Abstract
Purpose
The safety profile of the transcutaneous medial canthal incision for access to the medial orbit is assessed with a focus on the risk of post-operative iatrogenic epiphora.

Methods
A retrospective chart review of patients undergoing medial orbitotomy via the transcutaneous medial canthal incision was performed. Patients with a minimum of 3 months of follow-up were included and post-operative complications were assessed and characterized.

Results
One-hundred-fifty patients were included in the study. A total of 4 complications were identified, including one each of the following: nasolacrimal duct obstruction, hypertrophic scar, suture granuloma and soft tissue infection. Only the nasolacrimal duct obstruction required surgical intervention.

Discussion
Access to the medial orbit has been achieved through a variety of approaches, each with their own benefits and risk profile. The transcaruncular approach has increased in usage as a means to avoid a visible cutaneous scar and decrease the risk of iatrogenic epiphora, however, there are specific patients who may have relative contraindications to this approach. The current study demonstrates the low risk profile of the transcutaneous medial canthal incision, specifically the minimal risk of iatrogenic damage to the nasolacrimal outflow system. This approach is another useful tool which orbit surgeons should be familiar with to offer as an option to patients requiring medial orbitotomy.

Abstract
Abstract
Purpose
To investigate the effects of surgical and medical treatments on chronic kidney disease (CKD) patients with secondary hyperparathyroidism (SHPT).

Materials and methods
A total of 198 CKD patients with SHPT were identified at Tongji Hospital from January 2013 to June 2017.

Results
Surgical group (53 patients) received maintenance dialysis for 78.0 ± 4.9 months, while medical group (84 patients) for 62.0 ± 6.4 months. The serum intact parathyroid hormone (iPTH) in surgical group reduced apparently compared with medical group (P = 0.015) and maintained satisfied result during three years of follow-up (67.4 ± 7.4 pg/ml). The recurrence rate in surgical group was 7.5% and in medical group was 15.5% (P = 0.024). Beyond that, 5 (5.9%) patients suffered persistent hyperparathyroidism in medical group.

Conclusion
Although the progress of medical treatment is changing rapidly, surgical treatment is still an effective way to control serum iPTH and calcium chronically for SHPT patients. Complex SHPT patients can also receive satisfied effect by surgical treatment, without apparently increasing the risk of complications.

Abstract
Abstract
Foreign body granulomas can develop even several years after autologous fat or filler injection. In some instances the foreign body granulomas have been found at sites other than the original injection site. We present a case of a 48-year-old male with reported "hyaluronic acid fillers" injected into his upper and lower eyelids several years prior. He subsequently developed periorbital swelling with negative allergic and rheumatologic workup. The patient ultimately underwent a blepharoplasty for improvement of the swelling. Histopathology suggested silicone granulomas of the upper and lower eyelid. This case illustrates the importance of keeping foreign body granulomas on the differential for all patients with a history of facial dermal filler injections. Although hyaluronic acid is the most common dermal filler, providers should suspect the use of other dermal fillers including those not FDA approved particularly when common conservative treatment methods are not sufficient.

Abstract
Abstract
The management of invasive fungal sinusitis differs greatly from the management of herpes simplex virus (HSV) of the nose in immunocompromised patients. However, the diagnosis may be uncertain and a delay in treatment can lead to mortality. Here we describe the successful medical management of a series of immunocompromised pediatric patients with HSV lesions of the nose with the initial concern for invasive fungal sinusitis. The diagnosis of HSV herpes was supported by positive polymerase chain reaction (PCR) testing of the nasal lesion. To our knowledge, these are the first cases described in the pediatric literature, emphasizing the need to include this entity on the differential.

Abstract
Abstract
Background
Human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) has a patient demographic, presentation, and clinical treatment response distinct from HPV-unassociated OPSCC. The heterogeneity in presentation and diagnosis within a patient population with HPV-positive OPSCC and its impact on times to presentation, diagnosis, and treatment have yet to be characterized.

Participants
Patients with biopsy-proven p16-positive OPSCC seen and/or treated at our institution between 2008 and 2018. Of 136 patients with OPSCC seen and/or treated at our institution, 101 met criteria for inclusion.

Methods
Patients were grouped by several parameters including presenting symptom category (asymptomatic neck mass, neck mass with primary-site symptoms, or primary-site symptoms without a neck mass), p16 status on fine-needle aspiration (FNA), and date of presentation. Median time intervals between presentation to imaging, biopsy, and treatment were compared within each parameter using the Kruskal-Wallis test with a significance level of 0.05.

Results
Sixty-five of the 101 study patients presented with a neck mass. Patients without a neck mass had a longer interval from presentation to imaging than patients with a neck mass (median 4 vs 0 days, p = 0.025). Initial FNA obtained on 61 patients was positive for p16 in 19 patients. Unknown or negative p16 status on FNA was associated with shorter intervals from initial imaging to treatment initiation (39 vs 46.5 days, p = 0.045). Patients presenting in the final three years had a longer interval from presentation to treatment initiation (55 vs 41 days, p = 0.024).

Conclusion
A neck mass is absent from the clinical picture of a substantial proportion of HPV-associated OPSCC patients. Primary-site symptom category and regional metastasis were not associated with differences in times to diagnosis or treatment initiation at this major referral center. The increased awareness and complexity of treatment decisions related to OPSCC may contribute to the delays in treatment initiation observed in patients with p16-positive FNAs and those who presented in more recent years.

Abstract
Abstract
Purpose
Metabolic syndrome (MetS) was reported to a risk factor of developing idiopathic sudden sensorineural hearing loss (ISSNHL), but limited data exist on its effect on the recovery.

The purpose of this study was to evaluate the impact of (MetS) and its components on recovery of patients with ISSNHL.

Material and methods
228 ISSNHL patients were divided into MetS group and Non-MetS group according to the diagnostic criteria of MetS, and demographic and clinical characteristics and hearing recovery were reviewed between two groups.

Results
In total, 86 (37.7%) patients in MetS group, and 142 (62.3%) patients in Non-MetS group. The rate of hypertension, diabetes mellitus, low HDL-C, high TG and obesity were significantly higher in the MetS group than those in the Non-MetS group (P < 0.05). The complete recovery rate and partial recovery rate were significantly lower in the MetS group than those in the Non-MetS group. According to the multivariate analysis, MetS was significantly associated with a poor prognosis; high initial hearing threshold and presence of diabetes mellitus were correlated with a poor prognosis (P < 0.05).

Conclusions
These results suggest that MetS has a negative impact on the hearing recovery of ISSNHL. High initial hearing threshold and diabetes mellitus were indictors of a poor prognosis of ISSNHL.

Abstract
Abstract
Purpose
Health concerns around cannabis (marijuana) use have focused on the possible relationship with psychosis and lower airway health, however; the effect of cannabis smoking on upper airway health has received less attention. The aim of this study is to investigate difference between exclusive tobacco cigarettes smoking compared with tobacco plus cannabis smoking regarding severity of chronic rhinosinusitis (CRS).

Material and methods
A prospective cross-sectional study with two groups of CRS patients recruited (Group 1: tobacco cigarettes smokers; 100 patients and group 2: tobacco cigarettes smokers and also cannabis users; 100 patients). Recruitment occurred in a general practice in Egypt. Cannabis use was recorded by self-report. Severity of CRS was assessed and compared between 2 groups using SNOT-20 questionnaire, Lund-Mackay CT score and Lund-Kennedy (LK) endoscopy Score.

Results
Group 2 patients (tobacco plus cannabis smokers) had significantly higher mean of assessment cores (SNOT-20 (P = 0.005), Lund-Mackay CT score (P = 0.006) and Lund-Kennedy (LK) endoscopy Score (P = 0.005)). Group 2 patients also had significantly higher mean of facial pain/pressure, difficulty sleep, and wake at night, lack of sleep, wake up tired, fatigue, reduced productivity, reduced concentration, frustration/restless/irritable, sad and embarrassed compared to patients in group 1.

Conclusion
Adult patients who smoked tobacco cigarettes plus cannabis mixed with tobacco had greater health related quality of life burden and more severe CRS compared to patients who smoked tobacco cigarettes only.

Abstract
Abstract
Purpose
Laryngeal squamous-cell carcinoma (LSCC) is the second most common malignant tumor of head and neck squamous cell carcinoma. The study was aimed to identify key long non-coding RNAs (lncRNAs) biomarkers for LSCC.

Methods
Differentially expressed lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) between LSCC and adjacent tissues were obtained based on The Cancer Genome Atlas. DElncRNA-DEmRNAs co-expression and DElncRNA-nearby-target DEmRNA interaction networks were constructed. Receiver operating characteristic and survival analysis were performed. A published dataset were as used to validate the result of bioinformatics analysis.

Results
We obtained 1103 DEmRNAs and 306 DElncRNAs between LSCC and adjacent tissues. A total of 338 DElncRNA-DEmRNA co-expression pairs and 229 DElncRNA-nearby-target DEmRNA pairs were obtained. Ten DElncRNAs and six DEmRNAs has great diagnostic value for LSCC. HOXB9 has potential prognostic value for LSCC. The results of GSE84957 validation were generally consistent with our results.

Conclusion
Our study provided clues for understanding the mechanism and developing potential biomarkers for LSCC.

Abstract
Abstract
Objective
In the setting of current national healthcare reform, it becomes especially relevant to understand the current state of healthcare disparities with regards to insurance status. To determine the impact of payer status on survival in parotid malignancy, we utilized the National Cancer Database (NCDB).

Study design
Retrospective database review.

Setting
National Cancer Database (2004–2012).

Subjects and methods
The NCDB was queried for cases of primary malignancy of the parotid gland between 2004 and 2012. The impact of payer status on overall survival was evaluated, as well as the relationship of insurance status with patient and tumor variables.

Results
15,815 cases met inclusion criteria. A majority had private insurance (47.8%), followed by Medicare (40.9%), Medicaid (5.0%), uninsured (3.2%) and other government sources (1.3%). Medicare patients had the lowest 5 and 10-year survival rates (50.7% (95% CI [49.3–52.1]) and 27.8% (95% CI [25.0–30.9]), respectively). On multivariable analysis, uninsured, Medicare, and Medicaid patients had worse overall survival than the privately insured (HR 1.42, 95% CI [1.17–1.74]; HR 1.29, 95% CI [1.17–1.42]; HR 1.36, 95% CI [1.13–1.62], respectively). Uninsured and Medicaid patients were more likely than the privately insured to present with advanced stage disease, nodal metastasis and longer times to treatment following diagnosis.

Conclusion
In parotid malignancy, uninsured, Medicaid, and Medicare patients have worse survival outcomes compared to those with private insurance. Uninsured and Medicaid patients also present with more advanced stage disease and have increased wait times before definitive treatment is initiated.

Abstract
Abstract
Purpose
This retrospective study was conducted to assess the epidemiological, clinical and histologic characteristics of incidentally identified and presurgically diagnosed papillary thyroid microcarcinomas less than or equal to 5 mm in size (small PTMC).

Materials and methods
Cases from October 2003 to February 2018 were retrieved from pathology databases, and their clinicopathological features were reviewed.

Results
There were a total of 182 cases of small PTMCs, 141 women and 41 men. The mean age at diagnosis was 53.5. Most of the small PTMCs were not detected on clinical examination and workup and were diagnosed incidentally during pathologic examination. 21.4% of small PTMCs showed multifocality, with 21 cases of unilateral multifocal lesions and 18 cases with bilateral multifocal tumors. Small PTMCs were most often follicular variant (51.9%) followed by classic type (47.5%). The average size of follicular variants appeared to be larger than that of the classic type PTMCs (2.84 ± 1.43 mm vs 2.26 ± 1.51 mm, P = 0.01). A total of 66 cases (36.3%) had regional lymph node sampling or selective neck dissection and 15 of these cases identified lymph node metastasis (22.7%). 46.7% of patients with node positive microcarcinomas were male compared with 16% male in group with negative lymph nodes (P = 0.03).

Conclusions
Small PTMCs (≤5 mm) are often multifocal and bilateral and histology is commonly both the classical and follicular variant of PTC. While often diagnosed incidentally small PTMC can lead to regional lymph node involvement in a significant portion of cases and evaluation of the regional lymph nodes should be considered in the clinical management of these patients.

Abstract
Abstract
In this case report, our patient developed sudden sensorineural hearing loss (SSNHL) after loud noise exposure during a popular cardiovascular group exercise cycling class. To increase awareness among all healthcare professionals of the effects of these modern-day group fitness classes on hearing loss, we describe this case and review the current literature on SSNHL and its management. A 35-year old man developed SSNHL in the setting of loud noise exposure during a high intensity aerobic exercise class. After a short course of oral steroids with no improvement, intratympanic steroids were administered weekly for three weeks. The patient showed minimal improvement; thus, hyperbaric oxygen therapy was conducted. Serial audiograms continued to show severe to profound mixed hearing loss in the right ear. In conclusion, individuals who participate in loud, high-intensity aerobic group-exercise classes should be careful of the potential for noise-induced hearing loss. Aerobic exercise may make these individuals more susceptible to noise-induced hearing loss. Early intervention is critical for any chance of recovery.

Case Studies Comparing Learning Profiles and Response to Instruction in Autism Spectrum Disorder and Oral and Written Language Learning Disability at Transition to High School
imageThis study investigated literacy learning in students with specific kinds of language challenges at a specific stage of schooling—transition to high school—when the language requirements of the curriculum can be especially challenging. For this exploratory research, a case study approach was adopted that compared 2 adolescent boys both with language learning problems but with 2 contrasting disabilities—autism spectrum disorder (ASD) versus oral and written language learning disability (OWL LD)—just before entry to ninth grade. Three research aims compared participants on (a) learning profiles assessed via a comprehensive psychoeducational assessment battery, (b) change in their learning profiles based on response to instruction to a computerized intervention, and (c) change in their personal narrative compositions and use of taught translation strategies collected during 6 lessons of the computerized intervention. Results indicated that participants demonstrated variable psychoeducational profiles and response to instruction that highlighted similar yet distinct patterns of strengths and weaknesses. Personal narrative writing samples showed that participants demonstrated distinct challenges, but only the participant with ASD showed no response to instruction and produced predominantly off-topic text. Results are discussed in reference to educational applications and future research design implications to understand the writing challenges experienced by children with ASD in reference to children with OWL LD or other specific learning disabilities.

Exploring the Effects of a Biopoem Writing Intervention on Middle School Students With Autism Spectrum Disorder
imageThe purpose of this study was to explore how poetry writing can promote growth in social cognition, writing, and disciplinary literacy for middle school students diagnosed with autism spectrum disorders. An interpretive qualitative content analysis design was used to explore the instructional discourse and written products of the participants during a writing intervention using biopoems to learn about important people in history. Main findings indicated that participants were able to recognize and use emotion/perspective taking words, that the biopoem structure was effective in organizing their writing and enhancing word choice, and that they demonstrated disciplinary literacy through perspective taking and identification of historical significance. The discourse that accompanied the biopoem lessons included evidence of thinking processes and emerging understandings that resulted from the writing process. The context of conversation also allowed for higher order thinking and intertextuality to occur. Implications for practice and future research are discussed.

Teaching Written Expression to Students With Autism Spectrum Disorder and Complex Communication Needs
Written expression is critical to the full participation of individuals with autism spectrum disorder and complex communication needs in a wide range of educational and community contexts. Unfortunately, the extant research on teaching writing to this unique population is limited and, thus, provides little guidance to practitioners in the design of instruction. In this article, the authors present a set of recommendations extracted from the available research literature on teaching writing to students with autism spectrum disorder, offer examples of their successful application, and suggest areas of future research.

Administrator Perspectives on Writing Instructional Practices for Students With Complex Learning Needs: A Pilot Study
imageThe adoption of national literacy standards has resulted in writing becoming a priority for students with complex learning needs (CLN). Given extrinsic (school-based) and intrinsic (student-based) barriers, there is a need to understand how educational systems can provide innovative research- and standards-based writing instruction for these students. The creation of new educational standards and expectations, however, does not result in rapid and immediate change in how instruction occurs for these students. The purpose of this pilot study was to collect data concerning the knowledge, attitudes, and observed barriers toward writing instruction for students with CLN as perceived by educational administrators. Method: This preliminary study was anchored in the field of implementation science to better understand readiness, adoption, and sustainability of innovative writing instructional practices for students with CLN. Administrator perceptions were obtained through didactic interviews, and a qualitative research design was used to understand themes from the data. Results: Results showed that a central challenge across educators is a lack of awareness that change in instructional practice is needed, as well as a perception that these students are not capable of becoming writers. Educational administrators also identified factors that increase positive outcomes when implementing writing instruction for students with CLN. Conclusions: To effectively implement writing instruction for students with CLN, educational administrators will need to consider barriers that impact readiness, adoption, and sustainability and develop systematic solutions that increase overall success.

Abstract

Modeling fine-scale spatial and temporal patterns of air pollutants can be challenging. Advanced spatio-temporal modeling methods were used to predict both long-term and short-term concentrations of six criteria air pollutants (particulate matter with aerodynamic diameter less than or equal to 10 and 2.5 μm [PM10 and PM2.5], SO2, NO2, ozone and carbon monoxide [CO]) in Beijing, China. Monitoring data for the six criteria pollutants from April 2014 through December 2017 were obtained from 23 administrative monitoring sites in Beijing. The dimensions of a large array of geographic covariates were reduced using partial least squares (PLS) regression. A land use regression (LUR) model in a universal kriging framework was used to estimate pollutant concentrations over space and time. Prediction ability of the models was determined using leave-one-out cross-validation (LOOCV). Prediction accuracy of the spatio-temporal two-week averages was excellent for all of the pollutants, with LOOCV mean squared error-based R2 (R2mse) of 0.86, 0.95, 0.90, 0.82, 0.94 and 0.95 for PM10, PM2.5, SO2, NO2, ozone and CO, respectively. These models find ready application in making fine-scale exposure predictions for members of cohort health studies and may reduce exposure measurement error relative to other modeling approaches.

Abstract

The adverse health effects of inhaled particulate matter (PM) are global concern. Yet, in general, estimating the exposure to PM is challenging due to the sparsity of standard air quality monitoring stations and the low accuracy of dispersion models when high spatial resolution is required. The city of Elad, Israel, is situated less than 1 km from the Migdal Tzedek stone quarry, and public concerns were raised regarding the impact of the quarry's PM emissions on the city air quality.

This work describes a year-long campaign of continuous measurements of particle number concentration (PNC) in few locations in the city and its vicinity, using a network of low cost optical particle counters (OPCs). To assess the possible impact of the quarry on the city we examined the OPCs' accuracy, coherency, and their capability to detect the quarry's impact on the PNC levels in the city. Using PNC time series in two size channels from a network of five nodes, PM10 and PM2.5 records from a nearby reference air quality monitoring station, and meteorological data, we could conclude that the quarry's impact on the city was small relative to the background PNC levels. Yet, more importantly, this work demonstrates the use of a network of low cost OPCs for responding to an environmental query for which the sparse standard air quality monitoring observations were not sufficient. The trade-offs between deployment of a network of cheap low-quality instruments and the use of a single high-end device are discussed.

Abstract

Volatile organic compounds (VOCs) pollution, which is closely linked to photochemical smog and secondary organic aerosols, has become a severe concern in China. Therefore, we compiled a new high-resolution emission inventory for the industrial non-methane Volatile organic compounds (NMVOCs) using "bottom-up" approaches throughout 2010 and 2016. In this work, the industrial sources were divided into five major categories, and 108 specific sources, as well as an emission factor database, was developed for industrial NMVOCs. Results indicated that the total NMVOCs emissions from industrial sources increased from 16.88 Tg in 2010 to 21.04 Tg in 2016 at an annual average rate of 3.7%. The five major source categories including "production of VOCs", "storage and transportation", "industrial processes using VOCs as raw material", "processes using VOCs-containing products", and "fossil fuel combustion" generated 1.92 Tg, 0.94 Tg, 6.54 Tg, 10.04 Tg, and 1.60 Tg NMVOCs, respectively, in 2016. Coke production, plastic manufacturing, raw medicine industry, and architectural decoration were the primary sources of industrial NMVOCs and emissions of these sources increased by 140 Gg, 190 Gg, 640 Gg, and 700 Gg between 2010 and 2016. The emissions displayed distinct spatial characteristics, with significantly higher emissions in the Beijing-Tianjin-Hebei region, the Pearl River Delta, the Yangtze River Delta, and the Cheng-Yu region than in other areas. Shandong, Guangdong, Jiangsu, Zhejiang, and Henan were the top five provinces with the highest NMVOCs emissions, while the emission hotspots in the county-level were mainly distributed in Guangzhou urban area, Shanghai Pudong New Area, Hangzhou urban area, and Shenzhen urban area. The emissions in Henan province, Hubei province, and Cheng-Yu region increased significantly during the study period. Instead, emissions in some counties of Zhejiang province and Hebei province decreased than in 2010.

Use of radar rainfall to model deposition of radionuclides

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Author(s): Susan J. Leadbetter

Abstract

Accurate precipitation information is necessary for modelling the deposition of radionuclides following an accidental release of radioactive material to the atmosphere. The increase in resolution of numerical weather prediction models (NWP) has led to precipitation which looks more realistic but performs poorly when compared to observations using traditional grid-point statistics. Dispersion models have the ability to use precipitation information derived from radars. This study looks at the differences in estimates of air activity and deposition when precipitation information from a high resolution NWP is replaced by precipitation information from radar. Using a hypothetical release and a year's worth of meteorological data the results show that in around a third of cases there is a significant difference in the amount of deposition estimated when NWP precipitation is used compared to cases where radar precipitation is used. The results also show a small number of cases where air activity concentrations vary significantly between the runs.



Heterogeneous atmospheric degradation of current-use pesticides by nitrate radicals

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Author(s): Coraline Mattei, Henri Wortham, Etienne Quivet

Abstract

In the atmosphere, pesticides are distributed between gaseous and particulate phases according to their physicochemical properties. In these two phases, they can react with atmospheric oxidants such as ozone, hydroxyl radical and nitrate radicals. Heterogeneous kinetics of the degradation by nighttime nitrate radicals are not well described. In this study, the heterogeneous reactivity with nitrate radicals of eight current-use pesticides (i.e., difenoconazole, tetraconazole, cyprodinil, fipronil, oxadiazon, pendimethalin, deltamethrin, and permethrin) adsorbed on silica model particles was investigated using laboratory experiments with in-situ nitrate radicals generation and concentration measurement. Under these experimental conditions, all pesticides were degraded. Atmospheric half-lives calculated with a Langmuir-Rideal model ranged between 8 days and 16 days and between 2 days and 11 days according to a Langmuir-Hinshelwood model for an atmospheric nitrate radicals concentration of 20 ppt. Results obtained can contribute to a better understanding of the atmospheric fate of pesticides in the particulate phase and show the importance of their degradation by nitrate radical compared to their degradation by other oxidants such as ozone and hydroxyl radicals.

Fine and ultrafine particles concentrations in vape shops

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Author(s): Charlene Nguyen, Liqiao Li, Chanbopha Amy Sen, Emilio Ronquillo, Yifang Zhu

Abstract

Vape shops are widespread due to the popularity of electronic cigarettes (e-cigs) as an alternative to tobacco cigarettes. In this study, sixty-seven Southern California vape shops were randomly surveyed for building characteristics, ventilation, and business patterns. Based on the survey results, six representative shops were recruited for real-time measurements of indoor and outdoor fine and ultrafine particles concentrations on a busy and less busy day. Occupancy, vaping frequency, and opening and closing of doors were recorded, and shop air exchange rate was determined. Indoor CO2, relative humidity, and temperature were also recorded. In addition, simultaneous measurements were taken at increasing distances away from a vaping area to assess the mixing and spatial profiles of particle levels inside the shops. During active vaping, real-time indoor particle number concentration and gravimetric-corrected PM2.5 mass concentration across the six vape shops varied from 1.3 × 104 to 4.8 × 105 particles/cm3 and from 15.5 to 37,500 μg/m3, respectively. The spatial profiles of particle number and mass were more uniformly mixed than expected in an indoor environment. Total vaping frequency was the main predictor of particle concentrations inside the vape shops when indoor-outdoor particle mass transfer is minimal (doors closed).

An evaluation of the air quality health index program on respiratory diseases in Hong Kong: An interrupted time series analysis

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Author(s): Tonya G. Mason, C. Mary Schooling, King Pan Chan, Linwei Tian

Abstract
Background

On December 30th, 2013, the Hong Kong government implemented the Air Quality Health Index (AQHI) alert programme warnings designed to reduce short-term effects of air pollution on population health. However, whether air quality alert programme warnings, such as the AQHI, reduce morbidity is still questionable. Using a quasi-experimental design, we conducted the first evaluation of the AQHI in Hong Kong focusing on respiratory morbidity.

Method

Interrupted time series with Poisson segmented regression from 2010 to 2016 was used to detect any sudden or gradual changes in emergency respiratory hospital admissions, adjusted for air pollutants (NO2, SO2, PM10, O3), temperature and humidity, when the AQHI policy was implemented. The findings were validated using three false policy study periods and digestive diseases as a control. We also assessed effects on specific respiratory diseases (respiratory tract infections (RTI), asthma, chronic obstructive pulmonary disease and pneumonia) and by age.

Results

From January 1st, 2010 to December 31st, 2016, 10576.98 deseasonalized, age-standardized hospital admissions for respiratory disease occurred in Hong Kong. On implementation of the AQHI, RTI admissions immediately dropped by 14% (relative risk (RR) 0.86 95% confidence interval (CI) 0.76–0.98). In age specific analysis, immediate reductions in hospital admissions were only apparent in children for RTI (RR 0.84, 95% CI 0.74–0.96) and pneumonia (RR 0.88, 95% CI 0.60–0.96).

Conclusion

Hong Kong's AQHI helped reduced hospital admissions in children, particularly for RTI and pneumonia. To maximize health benefits of the policy, at risk groups need to be able to follow the behavioral changes recommended by the AQHI warnings.

Development and application of an updated geospatial distribution model for gridding 2015 global mercury emissions

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Abstract

Mercury is a global pollutant that poses threats to ecosystems and to human health. Due to its global transport, mercury contamination is found in regions of the Earth that are remote from major emissions areas, including the Polar regions. Global anthropogenic emission inventories identify important sectors and industries responsible for emissions at a national level; however, to be useful for air transport modelling, more precise information on the locations of emission is required. This paper describes the methodology applied, and the results of work that was conducted to geospatially distribute anthropogenic mercury emissions as part of the global anthropogenic mercury emissions inventory for 2015 prepared by AMAP/UNEP for the Global Mercury Assessment (GMA) 2018 (UN Environment, 2019). This work includes the identification and use of emission point sources as well as distributing diffuse emissions for 21 emission (industry) sectors. The basic approach involves assigning emission estimates to geo-located point sources, using reported emissions information where available, and otherwise assigning a modelled emission to the point. Emissions which cannot be assigned to point sources are distributed using sector-specific proxies. Mercury speciation highly depends on industry processes and air pollution control technology. Different Hg speciation ratios are therefore applied per sector and country technology level. The resulting global emission datasets include total mercury (HgT), gaseous elemental mercury (Hg0), divalent mercury (Hg2+) and particulate mercury (HgP) in kg per year per raster cell (kg/a). The spatial resolution is flexible and the vertical resolution of the data is based on a set of predefined height classes. The resolution of the GMA2018 emission data is 0.25° × 0.25° with three (physical emission) height classes (0–50, 50–150 and > 150m). A comparison with the EMEP European mercury emission was made based on spatial correlation between the two datasets. Suggested improvements for future work include the further development of proxy data and the implementation of a more structured reporting of emissions by countries.



Meteorological parameters and gaseous pollutant concentrations as predictors of daily continuous PM2.5 concentrations using deep neural network in Beijing–Tianjin–Hebei, China

Publication date: 15 August 2019

Abstract

The deep learning model can simulate the complex nonlinear relationship between PM2.5 and aerosol optical depth (AOD), and has great application potentiality in PM2.5 inversion. However, the underestimation of high PM2.5 concentrations problem is still exist in heavily polluted Beijing–Tianjin–Hebei (JingJinJi) region due to AOD cannot adequately represent the correlation between high PM2.5 concentrations and independent variables and neglected the effects of missing AOD. Thus, the long- and short-term PM2.5 exposure risk estimate was reduced. This work introduces gaseous pollutant data (NO2, SO2, CO, and O3) related to primary emission and secondary transformation of pollutants as predictors into a deep neural network model to improve the underestimation of high PM2.5 concentrations based on AOD and meteorological factors. We predicted the PM2.5concentration in the missing AOD areas, generated a daily continuous PM2.5 spatial distribution, and reduced estimated bias due to AOD deficiency. Grid-based 10-fold cross-validation (CV) was used to test the model performance. Results show that daily PM2.5 concentration CV R2 is 0.87 and the root-mean-square prediction error (RMSE) is 27.11 μg/m3. The CV R2 and RMSE are higher by 0.12 and lower by 9.72 μg/m3 than the model without gaseous pollutants (GASS) as predictors. In including the missing AOD, the average concentration of PM2.5 CV R2 is 0.86 and the RMSE is 16.95 μg/m3 in heavy polluted winter; the CV R2 and RMSE are higher by 0.07 and lower by 3.95 μg/m3, respectively, than when the missing AOD was excluded. Prediction results of PM2.5 spatial distribution show that the model has high prediction accuracy and provides a complete and highly accurate spatiotemporal distribution characteristics for long- and short-term PM2.5 exposure studies, and reduces exposure misclassification of PM2.5 in heavily polluted areas.

Characterization of trace aerosol compositions produced during the OH radical-initiated photooxidation of β-pinene

Publication date: 15 August 2019

Source: Atmospheric Environment, Volume 211

Author(s): Peng Zhang, Jingyun Huang, Jinian Shu, Pengkun Ma, Bo Yang

Abstract

The detailed molecular composition of laboratory-generated secondary organic aerosols (SOA) during the high-NO photooxidation of β-pinene (βP) was investigated using a novel thermal desorption dichloromethane-assisted low-pressure photoionization mass spectrometry (TD-CH2Cl2-assisted LPPI-MS) technique. We found that protonated norpinone gave the highest signal intensity, which supported that assumption that this compound was the key oxidation species responsible for promoting βP-SOA formation. In addition to the previously identified monomers (i.e., 2,2-dimethylcyclobutyl-1,3-dicarboxaldehyde (m/z 140), pinene aldehyde (m/z150), myrtenol (m/z 152), (2,2-dimethyl-3-acetyl)-cyclobutylformate (m/z 156), pinene acid (m/z 166), and isomers of pinalic-3-acid (m/z 170)), two additional nitrogen-containing species (i.e., C10 hydroxy nitrate and C10carbonyl nitrate) were also observed at m/z values of 214 and 216 in the mass spectrum of βP-SOA. Furthermore, the losses of 18 (H2O), 46 (NO2), and 64 (H2O + NO2) were attributed to the typical fragmentation pathways of the two nitrogen-containing species. Overall, these results not only contribute to an improved understanding of βP-SOA formation, but they also indicate that TD-CH2Cl2-assisted LPPI-MS can be used as a novel detection means to study SOA formation.
