Swell and Wind Wave Inversion Using a Single Very High Frequency (VHF) Radar
Authors: Alattabi Zaid R. , Cahl Douglas , Voulgaris George 
Published: April 2019

AbstractA hybrid, empirical radar wave inversion technique that treats swell and wind waves separately is presented and evaluated using a single 48-MHz radar unit and in situ wave measurements. This hybrid approach greatly reduces errors in radar wave inversion during swell seas. Our analysis suggests that, prior to the inversion, the second-order spectrum should be normalized using Barrick’s weighting function because this process removes harmonic and corner reflection peaks from the inversion and improves the results. In addition, the resulting calibration constants for the wind wave component are not wave-frequency dependent and are similar in magnitude to those found in previous studies using different operating-frequency radars. This result suggests radar frequency independence, although additional experimental verification is required. The swell component of the model presented here ignores the effect of swell’s propagation direction on the radar signal. Although this approach has several limitations and may only be useful near the coast (where swell propagates close to perpendicular to the coastline), the resulting wave inversion is accurate even when swell is propagating close to perpendicular to the radar beam direction. RMS differences relative to in situ wave height measurements range from 0.16 to 0.25 m as the radar beam angle increases from 22° to 56°.
Diurnal Cycle of Surface Winds in the Maritime Continent Observed through Satellite Scatterometry

Published: April 2019

AbstractThe diurnal cycle of surface winds throughout the Maritime Continent plays a significant role in the formation of precipitation over the islands of the region and over the surrounding seas. This study investigates the connection between the diurnal cycles of surface wind and offshore precipitation using data from four satellite scatterometer instruments and two satellite precipitation radar instruments. For the first time, data from three scatterometer instruments are combined to yield a more temporally complete picture of the surface wind diurnal cycles over the Maritime Continent’s surrounding seas. The results indicate that land–sea breezes typically propagate over 400 km offshore, produce mean wind perturbations of between 1 and 5 m s−1, and propagate as gravity waves at 25–30 m s−1. Diurnal precipitation cycles are affected through gravity wave propagation processes associated with the land–sea breezes, and through the convergence of land breezes from nearby islands. These observational results are then compared with previous mesoscale modeling results. It is shown that land–sea breezes occur too early, and are too intense in these modeling results, and this may partly explain why these modeling results also exhibit an early, overly intense diurnal precipitation cycle. This study also investigates variations in the diurnal cycle of surface winds at seasonal and intraseasonal time scales. Previous work has suggested that seasonal and intraseasonal variations in surface heating affect the land–sea breeze circulation and diurnal precipitation cycles; we argue that variations in background winds also play a defining role in modulating coastally influenced local winds.

Authors: Vu Lien H , Kellum John A , Federspiel William J , Cove Matthew E 
Published: April 2019

Background: Extracorporeal carbon dioxide removal may be used to manage hypercapnia, but compared to dialysis, it’s not widely available. A recent in vitro study showed that dialysis with low bicarbonate dialysates removes CO2. Objective: To show that bicarbonate dialysis removes CO2 in an animal model to validate in-vitro findings and quantify the effect on arterial pH. Methods: Male Sprague-Dawley hypercapnic rats were dialyzed with either a conventional dialysate (PrismasolTM) or a bicarbonate-free dialysate (Bicarb0). The effect of dialysis on standard blood gases and electrolytes was measured. Results: Partial pressure of CO2 and bicarbonate concentration in blood decreased significantly after exposure to Bicarb0 compared to PrismasolTM (filter outflow values 12.8 vs 81.1 mmHg; p < 0.01 for CO2 and 3.5 vs 22.0 mmol/L; p < 0.01 for bicarbonate). Total CO2 content of blood was reduced by 459 mL/L during dialysis with Bicarb0 (filter inflow 546 ± 91 vs filter outflow 87 ± 52 mL/L; p < 0.01), but was not significantly reduced with PrismasolTM. Conclusions: Bicarbonate dialysis removes CO2 at rates comparable to existing low-flow ECCO2R.

Objective This study aimed to examine the effects of a language education intervention (LEI) on social participation among emerging adults with autism. Methods This randomized clinical trial involved 86 emerging adults who had low social participation, as assessed by the Social Participation Questionnaire. Participants completed an LEI comprising cognitive, adaptive and rational thinking training to improve their ability to take part in social events. Repeated measures analysis of variance was used to analyse the data. Results The results indicated a significant increase in social participation among emerging adults who were exposed to the LEI compared with their counterparts in a wait list control group. Conclusion Language and speech institutions and hospitals should adopt the LEI procedures discussed in this research to help their autistic patients increase their participation in social activities.
Hepatitis D reactivation in a patient with metastatic renal cell carcinoma receiving sunitinib therapy
Authors: Akar Emre , Yücel Mehmet Haluk , Şahin Tunahan , Tural Deniz 
Published: April 2019

Background: Cytotoxic and immunosuppressive therapies for cancer treatment may allow hepatitis reactivation. Hepatitis due to viral hepatitis reactivation is detected in 14%–25% of hepatitis B surface antigen (HBsAg)–positive cancer patients undergoing anticancer treatments. Drug toxicity may be confused with hepatitis reactivation, which may cause a delay in diagnosis. Case report: A 60-year-old man with metastatic renal cell carcinoma was treated with sunitinib. Sixteen months after sunitinib inception, liver enzymes were elevated and viral hepatitis reactivation was detected as hepatitis delta virus infection in the HBsAg-positive patient. Conclusion: Cancer patients should be screened for viral hepatitis prior to immunosuppressive therapy or chemotherapy.

Published: April 2019

Objectives: To report the outcomes of young people (aged 14-30 years) treated for major mental disorders in a lay health worker (LHW) intervention model in a rural district of conflict-ridden Kashmir, India. Methods: Over a 12-month follow-up, LHWs collected data on symptoms, functioning, quality of life and disability, and patients’ and families’ service engagement and satisfaction. Results: Forty trained LHWs (18 males and 22 females) identified 262 individuals who met the criteria for a diagnosis of a major mental disorder, connected them with specialists for treatment initiation (within 14 days), and provided follow-up and support to patients and families. Significantly more patients (14-30 years) were identified during the 14 months of the project than those in all age groups in the preceding 2 years. At 12 months, 205 patients (78%) remained engaged with the service and perceived it as very helpful. Repeated measures ANOVA showed significant improvements in scores on the global assessment of functioning (GAF) scale (F[df, 3.449] = 104.729, p < 0.001) and all 4 domains of the World Health Organization quality of life (WHOQOL) brief version (WHOQOL-BREF) of the survey—Physical F(df, 1.861) = 40.82; Psychological F(df, 1.845) = 55.490; Social F(df, 1.583) = 25.189; Environment F(df, 1.791) = 40.902, all ps < 0.001—and a decrease in disability (F[df, 1.806] = 4.364, p = 0.016). An interaction effect between time and sex was observed for the physical health domain of the WHOQOL-BREF. Discussion and Conclusions: Our results show that an LHW-based service model, implemented in a rural setting of a low-to-middle income region plagued by long-term conflict, benefits young people with major mental disorders. We discuss the implications of our findings in the context of similar environments and the challenges encountered.

Published: April 2019

Purpose: The aim of this study was to investigate the incidence of clinically significant anterior chamber inflammation in a combined surgery, namely, phacoemulsification and Ex-Press miniature glaucoma device implantation, compared to phacoemulsification alone. Methods: A retrospective comparative study of a consecutive series of 210 participants above 18 years of age diagnosed with significant cataract and who required glaucoma surgery, namely, Ex-Press miniature glaucoma device implantation or cataract alone in one or both eyes. All were operated on by a single experienced glaucoma surgeon in a single medical center. A total of 231 eyes were included in this study. All cases underwent an uneventful surgery and were examined the day following the surgery for visual acuity, intraocular pressure, and signs of excessive anterior chamber inflammation (Standardization of Uveitis Nomenclature grading ⩾ 3). Results: The combined group included 55 eyes of 51 patients, of whom 15 (27.3%) demonstrated excessive anterior chamber inflammation. The phacoemulsification group included 176 eyes of 159 patients, of whom 12 (6.7%) demonstrated excessive anterior chamber inflammation. Visual acuity and intraocular pressure measurements showed no statistically significant difference between the two groups. Conclusion: The Ex-Press glaucoma device is efficient, safe, and known for its inert nature. However, combination of this procedure with phacoemulsification surgery might result in a condition encouraging excessive inflammation, which eventually could lead to excessive anterior chamber inflammations if not treated vigorously. Emphasizing and recognizing the risks, especially in glaucoma patients, is important.
Malignancy in Giant Cell Tumor of Bone: A Review of the Literature
Authors: Palmerini Emanuela , Picci Piero , Reichardt Peter , Downey Gerald 
Published: April 2019

Background: Primary and recurrent giant cell tumor of bone is typically benign; however, rarely giant cell tumor of bone can undergo malignant transformation. Malignancy in giant cell tumor of bone may be primary (adjacent to benign giant cell tumor of bone at first diagnosis) or secondary (at the site of previously treated giant cell tumor of bone). Malignant giant cell tumor of bone has a poor prognosis; it is important to distinguish malignant from benign lesions to facilitate appropriate management. The true incidence of malignant giant cell tumor of bone is not known, probably owing to inaccurate diagnosis and inconsistent nomenclature. We have analyzed current data to provide a robust estimate of the incidence of malignancy in giant cell tumor of bone. Methods: A literature search was performed to source published reports of primary and secondary cases of malignant giant cell tumor of bone. Studies that reported a denominator were used to estimate the incidence of malignancy. Results: We identified 4 large series of patients with malignant giant cell tumor of bone that provided data on 2315 patients with giant cell tumor of bone. Across these studies, the cumulative incidence of malignancy was 4.0%; the cumulative incidence of primary malignancy was 1.6% compared with 2.4% for secondary malignancy. Our analyses confirmed that most malignant giant cell tumor of bone is secondary and occurs following radiation. In addition, data from 8 small series showed that 4.8% of patients with giant cell tumor of bone who received radiation therapy developed secondary malignancy. Conclusions: Malignant giant cell tumor of bone is rare, and its identification is hindered by a lack of clear diagnostic criteria. For optimal care of patients with giant cell tumor of bone, we recommend: comprehensive histologic sampling to ensure accurate diagnoses; watchful follow-up, particularly for patients treated with radiation; and timely treatment of local recurrence.
Efficacy of observational hand hygiene audit with targeted feedback on doctors’ hand hygiene compliance: A retrospective time series analysis
Authors: Smiddy Maura P , Murphy Olive M , Savage Eileen , Fitzgerald Anthony P , O’ Sullivan Brenda , Murphy Catriona , Bernard Margaret , Browne John P 
Published: April 2019

Background: Healthcare-associated infection compromises patient safety. Compliance with hand hygiene (HH) guidelines has been shown to be an effective method of reducing infection; however, it remains suboptimal and poorer among doctors compared to other healthcare workers. The aim of this study is to determine the relationship between an individualised observational hand hygiene audit (OHHA) and feedback intervention with observed HH compliance. Methods: We used a retrospective interrupted time series design using OHHA data from a five-year period, 2011–2015. OHHA indicated poorer HH compliance among doctors than other healthcare workers in a 345-bed acute private hospital. An increase in orthopaedic surgical site infection prompted additional auditing of the orthopaedic unit further identifying substandard HH compliance among orthopaedic surgeons. In addition to ongoing HH interventions, an individualised hand hygiene audit and feedback intervention focusing on consultant orthopaedic surgeons was implemented. Observed HH compliance improved. The intervention was then extended to include all consultant doctors at the study site. Audit was implemented by trained clinical nurse managers during clinical rounds. Written audit feedback was provided by the infection prevention and control team. Results: HH compliance increased significantly among both orthopaedic surgeons and other consultant doctors, P < 0.05. Conclusion: An individualised audit and feedback intervention was effective in improving compliance. Incorporation of OHHA with individualised feedback into routine daily practice needs to be considered as a quality improvement opportunity. This study has the potential to inform other audit and feedback interventions to maximise effectiveness and ensure implementation.
A Structural Equation Modeling Analysis of Parental Factors Underlying the Demand for Private Supplementary Tutoring in China
Authors: Liu Junyan 
Published: April 2019

Purpose: Private supplementary tutoring has been increasingly used by parents as part of wider strategies to assist their children’s education careers in China. With a theoretical lens of parentocracy, this article aimed to investigate the influential parental factors underlying the demand for private tutoring, focusing on parents’ socioeconomic resources and attitudes toward education. Design/Approach/Methods: This article drew upon data from the 2014 iteration of the China Family Panel Studies. Structural equation modeling (SEM) analysis was employed to explore the influences of parental factors. Findings: The SEM analysis confirmed that parental income, education, and aspirations on children’s education had both direct and indirect positive effects through the mediating factor of role construction on demand for tutoring. A multiple-group analysis was further conducted, and the difference in the patterns for urban and rural parents was explored. Parental occupation had no impact on demand for tutoring for rural parents but had both direct and indirect effects for urban parents. Both direct and indirect effects of household income on demand for tutoring were greater for urban parents than for rural parents. Originality/Value: This article examined the direct and indirect influences of parental factors on demand for private tutoring and explored the differences in patterns for urban and rural parents in a quantitative way. Findings have implications for education inequality.
Learning, Teaching, and Researching in Shadow Education in Hong Kong: An Autobiographical Narrative Inquiry
Authors: Yung Kevin Wai-Ho 
Published: April 2019

Purpose: This article aims to illustrate from the author’s insider perspective the lived experiences of engaging in private tutoring in Hong Kong as a tutee, a tutor, and a researcher and draw implications on several issues arising from the prevalence of shadow education. Design/Approach/Methods: This article adopted an autobiographical narrative approach. Data were collected through the author’s memoir of events, stimulated by the tutorial materials he used when he was a tutee and a tutor, his own video-recorded lessons of tutoring, and reflective journals from his research projects. Findings: Various issues are discussed based on the narrative of the author playing different roles in the tutoring industry, including (1) the positive and negative washback on mainstream education, (2) the lack of strict regulation of the quality of tutors and advertisements, and (3) how shadow education may exacerbate education inequality and how some tutorial companies and nonprofit organizations are addressing the issue. Originality/Value: This article, to the best of the author’s knowledge, is the only one that discusses the issues of shadow education from an author’s own personal experiences as a tutee, a tutor, and a researcher. It illustrates how practices and policies of the private tutoring industry are evolving in Hong Kong from an insider perspective.

Published: April 2019

Objective: The primary objective of our research was to determine the prevalence of dyspareunia and vulvodynia in a limited clinical sample of Colombian women. Methods: The study was composed of women who were seen in local Colombian medical clinics. A pilot survey was designed in Spanish to obtain patients’ demographic and medical history. Harlow’s validated questionnaire was incorporated into our survey to screen for dyspareunia and vulvodynia. Results: Five hundred and eighty-two women completed the survey and 96.2% (N = 560) reported being sexually active. The survey response rate was 96%. Among those who were initially screened and reported being sexually active, 51.8% (N = 290; 95% confidence interval: 47.7%–55.9%) described having pain with intercourse (dyspareunia) and 25.9% (N = 145; 95% confidence interval: 22.4%–29.7%) did not have pain. Of those who were sexually active, Harlow’s validated questionnaire was completed by 490 women: 27.6% (N = 135; 95% confidence interval: 23.7–31.75) described vulvar pain lasting longer than 3 months (vulvodynia); 51.9% (95% confidence interval: 43.1%–60.5%) had burning pain; 42.4% (95% confidence interval: 33.8%–51.0%) had sharp stabbing pain; 69.6% (95% confidence interval: 61.1%–77.2%) reported having pain during intercourse (dyspareunia). Conclusion: In this select population sample, the prevalence of dyspareunia ranged from 51.8% using a general survey to 69.6% using a validated questionnaire. The prevalence of vulvodynia was 27.6% (95% confidence interval: 23.7–31.75). This is higher than the prevalence of dyspareunia (45%) and vulvodynia (3%–16%) reported in the US general population.

Abstract
Background
Tobacco use and heavy episodic drinking (HED) commonly co-occur in young adults. We developed and tested usability of the Smoking Tobacco and Drinking (STAND) intervention for young adults delivered on Facebook.

Methods
To inform the intervention, focus groups were held with 25 young adults age 18 to 25 (12% female; Mean age = 20.4) who smoked cigarettes and reported at least one HED episode in the past month. Facebook intervention posts (N = 180) were tailored to readiness to quit smoking, and tested in two private Facebook behavioral change groups (Ready, Not Ready) with N = 29 young adults (10% female; Mean age = 20.8). Participants flagged posts in need of change, and we assessed engagement (comment frequency).

Results
Focus groups revealed preference for changing one substance at a time and greater receptivity to quitting smoking than reducing drinking. Mean comments per post were 5.3 (SD = 1.1) in Ready groups and 11.7 (SD = 5.1) in Not Ready groups; 94/180 (52.2%) posts were flagged for change. The level of engagement and the flagging of posts for change did not differ by group or by whether the post targeted tobacco, alcohol, or both substances combined (all p > .10). Overall, STAND was rated as easy to understand, providing sound advice, worthy of recommendation, and helpful (all agreement 100% among Ready; 50–70% among Not Ready).

Conclusions
The current findings informed development of a social media-based intervention targeting tobacco and alcohol use in young adults. Although there was greater interest in making changes in smoking than drinking behavior, receptivity and acceptability of the Facebook post messages in the STAND intervention was high overall. The intervention is being further refined for evaluation in a larger trial.
