Lagrangian Measurement of Steep Directionally Spread Ocean Waves: Second-Order Motion of a Wave-Following Measurement Buoy
Authors: McAllister M. L. , van den Bremer T. S. 
Published: September 2019

AbstractThe notion that wave-following buoys provide less accurate measurements of extreme waves than their Eulerian counterparts is a perception commonly held by oceanographers and engineers (Forristall 2000,J. Phys. Oceanogr.,30, 1931–1943,https://doi.org/10.1175/1520-0485(2000)030<1931:WCDOAS>2.0.CO;2). By performing a direct comparison between the two types of measurement under laboratory conditions, we examine one of the hypotheses underlying this perception and establish whether wave measurement buoys in extreme ocean waves correctly follow steep crests and behave in a purely Lagrangian manner. We present a direct comparison between Eulerian gauge and Lagrangian buoy measurements of steep directionally spread and crossing wave groups on deep water. Our experimental measurements are compared with exact (Herbers and Janssen 2016,J. Phys. Oceanogr.,46, 1009–1021,https://doi.org/10.1175/JPO-D-15-0129.1) and new approximate expressions for Lagrangian second-order theory derived herein. We derive simple closed-form expressions for the second-order contribution to crest height representative of extreme ocean waves—namely, for a single narrowly spread wave group, two narrowly spread crossing wave groups, and a single strongly spread wave group. In the limit of large spreading or head-on crossing, Eulerian and Lagrangian measurements become equivalent. For the range of conditions that we test, we find that our buoy behaves in a Lagrangian manner, and our experimental observations compare extremely well to predictions made using second-order theory. In general, Eulerian and Lagrangian measurements of crest height are not significantly different for all degrees of directional spreading and crossing. However, second-order bound-wave energy is redistributed from superharmonics in Eulerian measurements to subharmonics in Lagrangian measurement, which affects the “apparent” steepness inferred from time histories and poses a potential issue for wave buoys that measure acceleration.

Published: September 2019

Background: The prevalence of opioid abuse has become epidemic in the United States. Microdirect laryngoscopy (MDL) is a common otolaryngological procedure, yet prescribing practices for opioids following this operation are not well characterized. Objective: To characterize current opioid-prescribing patterns among otolaryngologists performing MDL. Methods: A cross-sectional survey of otolaryngologists at a national laryngology meeting. Results: Fifty-eight of 205 physician registrants (response rate 28%) completed the survey. Fifty-nine percent of respondents were fellowship-trained in laryngology. Respondents performed an average of 13.3 MDLs per month. Thirty-four percent of surgeons prescribe opioids for over two-thirds of their MDLs, while only 7% of surgeons never prescribe opioids. Eighty-eight percent of surgeons prescribed a combination opioid and acetaminophen compound, hydrocodone being the most common opioid component. Many surgeons prescribe non-opioid analgesics as well, with 70% and 84% of surgeons recommending acetaminophen and ibuprofen after MDL respectively. When opioids were prescribed, patient preference, difficult exposure and history of opioid use were the most influential patient factors. Concerns of opioid abuse, the physician role in the opioid crisis, and literature about postoperative non-opioid analgesia were also underlying themes in influencing opioid prescription patterns after MDL. Conclusions: In this study, over 90% of practicing physicians surveyed are prescribing opioids after MDL, though many are also prescribing non-opioid analgesia as well. Further studies should be completed to investigate the needs of patients following MDL in order to allow physicians to selectively and appropriately prescribe opioid analgesia postoperatively.

Published: September 2019

Objective The aim of this study is to assess the relationship between eye-tracking measures and perceived workload in robotic surgical tasks. Background Robotic techniques provide improved dexterity, stereoscopic vision, and ergonomic control system over laparoscopic surgery, but the complexity of the interfaces and operations may pose new challenges to surgeons and compromise patient safety. Limited studies have objectively quantified workload and its impact on performance in robotic surgery. Although not yet implemented in robotic surgery, minimally intrusive and continuous eye-tracking metrics have been shown to be sensitive to changes in workload in other domains. Methods Eight surgical trainees participated in 15 robotic skills simulation sessions. In each session, participants performed up to 12 simulated exercises. Correlation and mixed-effects analyses were conducted to explore the relationships between eye-tracking metrics and perceived workload. Machine learning classifiers were used to determine the sensitivity of differentiating between low and high workload with eye-tracking features. Results Gaze entropy increased as perceived workload increased, with a correlation of .51. Pupil diameter and gaze entropy distinguished differences in workload between task difficulty levels, and both metrics increased as task level difficulty increased. The classification model using eye-tracking features achieved an accuracy of 84.7% in predicting workload levels. Conclusion Eye-tracking measures can detect perceived workload during robotic tasks. They can potentially be used to identify task contributors to high workload and provide measures for robotic surgery training. Application Workload assessment can be used for real-time monitoring of workload in robotic surgical training and provide assessments for performance and learning.

Published: September 2019

Study’s purpose: To analyze the effectiveness of telephone intervention for the nursing diagnosis of delayed surgical recovery in older persons who have undergone cataract surgery. Design: Blinded, randomized, and controlled trial. A total of 95 patients of both sexes who were over 60 years old and had undergone cataract surgery were divided into an intervention group (48 patients) and a control group (47 patients), allocated using BioEstat 5.3 Software. Results: The intervention included postoperative follow-up recovery of cataracts and prevention of complications performed on the 1st, 4th, 10th, and 20th postoperative days. After the intervention, the intervention group had a decrease in the length of surgical recovery ( p = .000). The occurrence in the intervention group was 6.3%, while in the control group, it was 36.2% (odds ratio (OR) = 0.118; confidence interval (CI) = 1.02, 10.23). The number of nursing interventions nevertheless decreased during the telephone follow-up. Conclusion: For older persons, the telephone guidelines increase adherence to treatment, promote clinical improvement, promote surgical recovery over time, and improve independence and autonomy.

Authors: Peng Bo , Wang Qiang 
Published: September 2019

Objective This study was performed to identify the effects of different surgical approaches on the right coronary artery ostium in patients with congenital supravalvular aortic stenosis (SVAS) and to determine how to avoid surgically induced right coronary artery occlusion. Methods The surgical techniques and outcomes of 91 patients who underwent surgical treatment of SVAS from 2008 to 2015 in our institution were retrospectively reviewed to identify the causes of early death, reoperation, and extracorporeal membrane oxygenation (ECMO) support. Results Four perioperative deaths (Doty’s technique, n = 4), six cases of ECMO support (Doty’s technique, n = 4; Brom’s technique, n = 1; McGoon’s technique, n = 1), and eight reoperations (Doty’s technique, n = 5; Brom’s technique, n = 2; McGoon’s technique, n = 1) occurred. In cases of reoperation, adjustment of the shape and position of the right coronary sinus patch relieved the malignant arrhythmia. Conclusion Different surgical techniques have different effects on the right coronary artery. The shape of the patch inserted into the right coronary sinus should be carefully clipped to avoid distortion and ischemia of the right coronary artery.

Published: September 2019

Malaria affects health and general well-being of many people in the developing world. In India also, malaria is a major public health problem. It continues to be a leading cause of morbidity and mortality in many tropical regions of the world, despite global efforts to eradicate the disease. To achieve the targets of reducing malaria prevalence and preventing malaria epidemic, it is essential to have active community participation. Therefore, clear understanding of the Knowledge, Awareness and Perception (KAPs) of a particular community can help in framing the policy of prevention and promotion of any malaria control measure. In this context, the decision makers in the health sector are recognizing the importance of community’s KAPs on malaria and, thus, is gaining stimulus as one of the methods for malaria control. KAPs, however, play an important role in the improvement of health and health-seeking behaviour of a disease-burdened group. This study, therefore, investigates a local community’s KAPs on malaria in tribal areas of Vadodara District. The KAP investigates the community’s understanding of malaria transmission, their recognition of signs and symptoms, their treatment-seeking behaviours and community preventive measures and practices.

Published: September 2019

Objectives: Compare the clinical and radiological outcome of CFP stem with the MiniHip design in a prospective series, with special interest in intraoperative periprosthetic fracture (IPPF). Methods: We prospectively followed 101 cases treated with the MiniHip stem (Group 1) and 89 with the CFP stem (Group 2) operated between 2010 and 2014. No significant demographic differences were observed between both groups. Median follow-up was 72 months. Average stem length was 41% shorter in the MiniHip group ( p  < 0.001). Radiological parameters were measured and a logistcic regression model was created to evaluate factors associated with IPPF. Results: Mean mHHS improved from 54 to 95 in the MiniHip group ( p  < 0.001) and from 64 to 98 in the CFP group ( p  < 0.001). No significant differences were observed in terms of loosening, infection or instability. We observed 7 IPPFs (3.68%), 3 in group 1 and 4 in group 2. After adjusting for confounders, CFP was not associated with a greater risk of IPPF (OR 3.23; 95% CI, 0.250–42.034, p  = 0.368), however, a more complex fracture pattern was observed with this stem design. Prior acetabular fractures were associated with IPPF (OR 66.85; 95% CI, 1.142–3911, p  = 0.043). Compared to Dorr A femurs, type Dorr B appeared protective against IPPF (OR 0.039; 95% CI, 0.001–1.109, p  = 0.058). Valgus alignment tended to increase the risk of IPPF (OR 20.59; 95% CI 0.870–487.221, p  = 0.061). Conclusions: MiniHip showed similar radiological outcomes to CFP at short- to mid-term follow-up without increasing IPPFs with a shorter stem length. Given that CFP produced a more complex IPPF pattern, surgeons should be cautious with alignment of this particular design, especially in Dorr A femur.

Published: September 2019

Background: Urban emergency department (ED) patients have elevated smoking and substance use compared with the general population. We analyzed gender differences in smoking among an urban ED sample and assessed the contribution of substance use, demographic, and couple factors. Methods: We conducted a secondary analysis of data obtained from a cross-sectional, observational survey (N = 1037 participants) on drinking, drug use, and intimate partner violence (IPV). Gender-specific logistic regression models for current (past 30-day) smoking and multinomial regression models for smoking intensity (light: ⩽5 cigarettes per day [CPD]; moderate: 6 to 10 CPD; heavier: >10 CPD) were estimated. Results: Smoking prevalence was higher among men than women (35.5% vs 18.9%; P < .001). Substance use (frequency of intoxication, marijuana, amphetamine, and cocaine use), demographic (food insufficiency, unemployment), and couple-related factors (having a spouse/partner who smoked, IPV involvement, being in a same-gender couple) were differentially associated with current smoking and level of intensity among men and women. Conclusions: Emergency department staff should consider the impact of polysubstance use, food insufficiency, unemployment, and whether both partners in the couple smoke when screening patients for smoking and formulating cessation treatment plans. Women in same-gender relationships and those who have experienced IPV involvement may require additional referral.

Background: The objective of this study was to compare fatigue levels between subjects with and without COPD, and to investigate the relationship between fatigue, demographics, clinical features and disease severity. Methods: A total of 1290 patients with COPD [age 65 ± 9 years, 61% male, forced expiratory volume in 1 s (FEV1) 56 ± 19% predicted] and 199 subjects without COPD (age 63 ± 9 years, 51% male, FEV1 112 ± 21% predicted) were assessed for fatigue (Checklist Individual Strength-Fatigue), demographics, clinical features and disease severity. Results: Patients with COPD had a higher mean fatigue score, and a higher proportion of severe fatigue (CIS-Fatigue score 35 ± 12 versus 21 ± 11 points, p < 0.001; 49 versus 10%, p < 0.001). Fatigue was significantly, but poorly, associated with the degree of airflow limitation [FEV1 (% predicted) Spearman correlation coefficient = −0.08, p = 0.006]. Multiple regression indicated that 30% of the variance in fatigue was explained by the predictor variables. Conclusions: Severe fatigue is prevalent in half of the patients with COPD, and correlates poorly with the degree of airflow limitation. Future studies are needed to better understand the physical, psychological, behavioural, and systemic factors that precipitate or perpetuate fatigue in COPD.
Using the pharmacy retail model to examine perceptions and biases of a UK population sample towards regulation of specific psychoactive drugs
Authors: James Edward , Robertshaw Thomas L , Pascoe Michael J , Chapman Fiona M , Westwell Andrew D , Smith Andrew P 
Published: September 2019

Background:Contemporary research indicates that the legal classifications of cannabis (Schedule 2, Class B), 3,4-methylenedioxymethamphetamine (MDMA) (Schedule 1, Class A) and psilocybin (Schedule 1, Class A) in the United Kingdom are not entirely based on considerations of harm and therapeutic utility. The legal classifications of the substances discussed are typically determined by legislators such as Parliament and, therefore, may be a reflection of the views or perceived views of the general public.Objective:The aim of the study was to provide an indication of the underlying psychology regarding the legislated sale of alcohol, tobacco, cannabis, MDMA and psilocybin in pharmacies according to a UK general population sample.Methods:A sample of 105 UK nationals was selected for the survey. Participants were asked questions on perceived relative harm of the five substances. After viewing contemporary information on reported relative harm and therapeutic applications, the participants were asked questions related to using the pharmacy retail model for the sale of the substances discussed. Participants who opposed the substances being sold primarily in pharmacies were asked to explain their rationale according to a predetermined list of options for each of the five drugs. Participants were also asked whether they consider it a human right to be legally permitted to consume the substances.Results:The participants' perceptions of relative harm (tobacco > MDMA > psilocybin > alcohol > cannabis) were not in agreement with the relative harm reported in the literature (alcohol > tobacco > cannabis > MDMA > psilocybin). Principal objections to the currently illicit substances being legally available in pharmacies include it sending the wrong message; it feels wrong; it is too dangerous; disliking the smell of cannabis; disapproval of the people; and not liking the idea of people using psychoactive drugs for entertainment or to have mystical/religious experiences. Overall, the participants determined that being legally permitted to consume the substances discussed is an issue of relevance to human rights. A majority of the male participants concluded that being legally permitted to consume alcohol, tobacco, cannabis and Psilocybe mushrooms is a human right in contrast to the majority of female participants who solely considered alcohol consumption to be a human right.Conclusions:The data suggest that the legal classifications may not simply be based on considerations of harm. Misperceptions of the dangers, biases and non-health-related aversions likely contribute to the continuation of policies that do not reflect the state of scientific research.

Published: September 2019

Background Development and uptake of digital health technologies benefit from cross-sectoral efforts from academia and industry. Our study aims to identify the barriers and facilitators associated with academia–industry collaborations in digital health in middle- and high-income countries. Methods Trained personnel conducted semi-structured interviews with 23 stakeholders who were active in industry, academia or both. Stakeholders were based in middle-income countries (including China) and high-income countries (including the United States) as defined by the World Bank. Interviews were conducted in the stakeholder’s language of choice (Chinese, n = 12; English, n = 11). Qualitative interview questions elicited perspectives on stakeholders’ experience with academia–industry collaboration, challenges faced, and factors that facilitated the process. Interviews were audiotaped, transcribed verbatim, thematically coded by bilingual coders and analyzed using inductive content analysis. Results Stakeholders in both academia and industry identified complementary roles, authentic communication between partners, and clearly outlined goals or expectations prior to the collaboration as primary facilitators for success. Misaligned goals or expectations, differences in timelines for productivity and difficulties balancing expectations for business outcomes versus generation of scientific evidence were identified as primary barriers. Stakeholders in high-income countries reported inauthentic communication as a significant barrier to collaboration, whereas those in middle-income countries did not. Conclusion Outlining and communicating openly about goals and expectations for timeline and priorities as well as establishing complementary roles will facilitate fruitful academia–industry collaborations in the future. Best practices for communication styles may be dependent on the cultural setting, and thus should be adopted accordingly.
First record of translocation in Culicidae (Diptera) mitogenomes: evidence from the tribe Sabethini

Published: September 2019

Abstract

Background
The tribe Sabethini (Diptera: Culicidae) contains important vectors of the yellow fever virus and presents remarkable morphological and ecological diversity unequalled in other mosquito groups. However, there is limited information about mitochondrial genomes (mitogenomes) from these species. As mitochondrial genetics has been fundamental for posing evolutionary hypotheses and identifying taxonomical markers, in this study we sequenced the first sabethine mitogenomes: Sabethes undosus, Trichoprosopon pallidiventer, Runchomyia reversa, Limatus flavisetosus, and Wyeomyia confusa. In addition, we performed phylogenetic analyses of Sabethini within Culicidae and compared its mitogenomic architecture to that of other insects.

Results
Similar to other insects, the Sabethini mitogenome contains 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. However, the gene order is not the same as that in other mosquitoes; the tyrosine (Y) and cysteine (C) tRNA genes have translocated. In general, mitogenome rearrangements within insects are uncommon events; the translocation reported here is unparalleled among Culicidae and can be considered an autapomorphy for the Neotropical sabethines.

Conclusions
Our study provides clear evidence of gene rearrangements in the mitogenomes of these Neotropical genera in the tribe Sabethini. Gene order can be informative at the taxonomic level of tribe. The translocations found, along with the mitogenomic sequence data and other recently published findings, reinforce the status of Sabethini as a well-supported monophyletic taxon. Furthermore, T. pallidiventer was recovered as sister to R. reversa, and both were placed as sisters of other Sabethini genera (Sabethes, Wyeomyia, and Limatus).
