Observations of Nonlinear Internal Wave Run-Up to the Surfzone
Authors: Sinnett Gregory , Feddersen Falk , Lucas Andrew J. , Pawlak Geno , Terrill Eric 
Published: January 2018

AbstractThe cross-shore evolution of nonlinear internal waves (NLIWs) from 8-m depth to shore was observed by a dense thermistor array and ADCP. Isotherm oscillations spanned much of the water column at a variety of periods. At times, NLIWs propagated into the surfzone, decreasing temperature by ≈1°C in 5 min. When stratification was strong, temperature variability was strong and coherent from 18- to 6-m depth at semidiurnal and harmonic periods. When stratification weakened, temperature variability decreased and was incoherent between 18- and 6-m depth at all frequencies. At 8-m depth, onshore coherently propagating NLIW events had associated rapid temperature drops (ΔT) up to 1.7°C, front velocity between 1.4 and 7.4 cm s−1, and incidence angles between −5° and 23°. Front position, ΔT, and two-layer equivalent height zIW of four events were tracked upslope until propagation terminated. Front position was quadratic in time, and normalized ΔT and zIW both decreased, collapsing as a linearly decaying function of normalized cross-shore distance. Front speed and deceleration are consistent with two-layer upslope gravity current scalings. During NLIW rundown, near-surface cooling and near-bottom warming at 8-m depth coincide with a critical gradient Richardson number, indicating shear-driven mixing.
Health-focused course content is associated with altered health behaviours in undergraduate university students
Authors: Guelfi Kym J , Ong Ming Jing , Peeling Peter 
Published: January 2018

Objective: To examine whether the completion of a course of study relating to preventive health and lifestyle risk factors was associated with alterations in health behaviours. Design: Within-group intervention, repeated-measures design. Setting: Health behaviours of university students studying a course focused on health and well-being. Method: Undergraduate university students ( n = 56) completed a questionnaire assessing health behaviours at the start and end of a course which was oriented towards a healthy lifestyle, concentrating on preventive health and lifestyle risk factors. Beliefs about the importance of various health behaviours addressed within the course content were also assessed. Results: Physical activity was unaltered across the duration of the course, while a number of dietary behaviours were improved, including an increase in the weekly frequency of eating breakfast, reduced frequency of adding salt to meals, increased frequency of choosing reduced fat dairy options, reduced frequency of consuming drinks with added sugar, and consuming alcohol ( p ≤ .05). Conclusion: Health-focused course content may benefit students through the knowledge gained that can be applied in future professional settings and also via positive alterations in their own health behaviours. These positive influences on health behaviour in early adulthood may have implications for lifelong health and well-being.
Cerebellar involvement in migraine
Authors: Kros Lieke , Angueyra Aristizábal Chantal A , Khodakhah Kamran 
Published: January 2018

Background Although there is a great wealth of knowledge about the neurobiological processes underlying migraine and its accompanying symptoms, the mechanisms by which an attack starts remain elusive, and the disease remains undertreated. Although the vast majority of literature focuses on the involvement of the trigeminovascular systems and higher systems it innervates, such as thalamic and hypothalamic nuclei, several lines of evidence implicate the cerebellum in the pathophysiology of migraine. Aim In this review, we aim to summarize potential cerebellar involvement seen from different perspectives including the results from imaging studies, cerebellar connectivity to migraine-related brain structures, comorbidity with disorders implying cerebellar dysfunction, similarities in triggers precipitating both such disorders, and migraine and cerebellar expression of migraine-related genes and neuropeptides. We aim to inspire an increase in interest for future research on the subject. Conclusion It is hoped that future studies can provide an answer as to how the cerebellum may be involved and whether treatment options specifically targeting the cerebellum could provide alleviation of this disorder.

Objectives: Self-harm is common in New Zealand (NZ) young people and can have short-term and long-term consequences, including suicide. This study was undertaken to examine the extent to which evidence-based approaches for addressing self-harm are offered by Infant, Child and Adolescent Mental Health Services (ICAMHS). Methods: A national survey of ICAMHS practitioners working with young people who self-harm was undertaken between May and July 2016. Results: Responses from 23 out of 30 ICAMHS confirmed self-harm was a familiar presentation and most commonly associated with diagnoses of depression, anxiety and borderline personality disorder. Cognitive behavioural therapy (47.1%, n = 8), dialectical behaviour therapy (47.1%, n = 8) and acceptance and commitment therapy (5.9%, n = 1) were the treatments of choice, but variably delivered. There were significant training gaps for all types of therapy. Conclusions: Although it is reassuring that many ICAMHS are using evidence-based approaches to address self-harm in young people, there is concerning variability in the way these therapies are delivered. Improvement in training in key modalities, further research into therapist performance and continuous evaluation of workforce development are needed to maximise the effectiveness of proven interventions and provide NZ young people with the state-of-the-art service they deserve.

Purpose: As many as 50% of patients with cancer develop acute skin reactions to some degree with radiotherapy. Proactive skin care is often recommended to minimise these skin reactions and maintain the integrity of the epidermal barrier; nevertheless, no consensual guidelines are systematically used. This multicentre, observational, prospective study evaluated the tolerability and benefit of supportive and barrier protective skin care products in preventing radiotherapy-induced skin reactions in 253 women initiating radiotherapy (exclusive or adjuvant) for breast cancer. Methods: Patients received a kit of 5 commercially available skin care products before the first radiotherapy treatment. The following variables were assessed: cutaneous adverse events, investigator-assessed skin reactions (oedema, erythema, dryness, desquamation) before and after radiotherapy course, investigator, and patient opinion on products benefit. Results were analysed by frequency of product use (heavy versus low). Results: Average age was 60 years (range: 34-85). Over 92% of patients reported good to excellent tolerance on irradiated skin for each product. During the 6-week radiotherapy period, we observed that heavy product users had less skin reactions than the low users, particularly within 10 days of radiotherapy initiation (8% versus 18%; p = .031). Positive physician’s opinion on product use was more frequent for high (66.6%) versus low (32%) users. Patient-assessed patient benefit index was generally >1, indicating relevant treatment benefit, with a tendency for better benefit in high versus low users. Conclusions: These results support recommendations to use skin care products to minimise the impact of secondary cutaneous reactions with radiotherapy cancer treatment.

Objective: To analyze the level of understanding of the brain death concept among medical students in universities in Spain. Methods: This cross-sectional sociological, interdisciplinary, and multicenter study was performed on 9598 medical students in Spain. The sample was stratified by geographical area and academic year. A previously validated self-reported measure of brain death knowledge (questionnaire Proyecto Colaborativo Internacional Donante sobre la Donación y Transplante de Organos) was completed anonymously by students. Results: Respondents completed 9275 surveys for a completion rate of 95.7%. Of those, 67% (n = 6190) of the respondents understood the brain death concept. Of the rest, 28% (n = 2652) did not know what it meant, and the remaining 5% (n = 433) believed that it did not mean that the patient was dead. The variables related to a correct understanding of the concept were: (1) being older ( P < .001), (2) studying at a public university ( P < .001), (3) year of medical school ( P < .001), (4) studying at one of the universities in the south of Spain ( P = .003), (5) having discussed donation and transplantation with the family ( P < .001), (6) having spoken to friends about the matter ( P < .001), (7) a partner’s favorable attitude toward donation and transplantation ( P < .001), and (8) religious beliefs ( P < .001). Conclusions: Sixty-seven percent of medical students know the concept of brain death, and knowledge improved as they advanced in their degree.
How Courts Structure State-Level Representation
Authors: Kastellec Jonathan P. 
Published: January 2018

AbstractI examine how courts condition the relationship between state-level public opinion and policy. The system of federalism in the United States allows federal and state courts to establish the types of policies that states are constitutionally allowed to implement. In particular, federal courts can set “federal floors” for policy, below which no states can go. State courts, in turn, can raise the level of this floor. Thus, both federal and state courts shape whether state policy can match the preferences of the median voter in a given state. Analyzing data on public opinion, judicial decisions, and state-level policy on the issue of abortion, from 1973 to 2012, I show that changes in the set of allowable abortion restrictions, according to the combined decisions of state and federal courts, significantly affect whether states implement majority-preferred policies. I also show that ignoring the influence of courts on the policymaking environment significantly affects the estimated level of policy congruence and thus conclusions about the scope of representation. These results demonstrate the importance of placing courts in the larger study of state-level representation.

Published: January 2018

Background/Rationale: Compensation strategies may contribute to greater resilience among older adults, even in the face of cognitive decline. This study sought to better understand how compensation strategy use among older adults with varying degrees of cognitive impairment impacts everyday functioning. Methods: In all, 125 older adults (normal cognition, mild cognitive impairment, dementia) underwent neuropsychological testing, and their informants completed questionnaires regarding everyday compensation and cognitive and functional abilities. Results: Cognitively normal and mild cognitive impairment older adults had greater levels of compensation use than those with dementia. Higher levels of neuropsychological functioning were associated with more frequent compensation use. Most importantly, greater frequency of compensation strategy use was associated with higher levels of independence in everyday function, even after accounting for cognition. Conclusion: Use of compensation strategies is associated with higher levels of functioning in daily life among older adults. Findings provide strong rational for development of interventions that directly target such strategies.

Authors: Caruana Ethan , Wigderowitz Carlos , Harrold Fraser 
Published: January 2018

Background The objective of the present study was to determine the size and position of the rotator cuff moment arms constructed from the cuff footprints, incident on the line of force acting through the humeral head. Methods Five humeri were dissected, leaving the footprints of the rotator cuff intact. Each of the rotator cuff footprints and the cartilage/calcar interface were digitized and the articular surface was scanned using a high precision surface laser scanner. All of the data were merged into the same coordinate system. The centroid of each cuff footprint, centroid of the articular surface of the humerus (G) and the centroid of the articular surface of the glenoid (P) were calculated. Moment arms were measured as the intersection of a perpendicular line of force from each footprint centroid onto the resultant line of force to the centroid of the Glenoid (P). Results The mean moment arms of the supraspinatus, infraspinatus and subscapularis muscles were incident close to the centroid (G), whereas teres minor was lateral to the centroid, consistently. Conclusions The teres minor moment arm aligned distal to the centroid of the sphere, consistently. The results may provide an understanding of the function of each muscle as a mobilizer or stabilizer of the glenohumeral joint. Further investigation is necessary.
Implementation of universal rapid human immunodeficiency virus screening on labor and delivery

Published: January 2018

Background: A case of mother to child transmission (MTCT) of HIV at a medical center in Washington, DC, resulted in the implementation of universal opt-out rapid testing of patients admitted for delivery. This article evaluates the policy’s efficacy and implementation. Methods: We evaluated the implementation using the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. Results: We could not evaluate decrease in MTCT rate secondary to low sample size ( n = 3324) and no true-positive results. Patients not tested ( n = 458) were predominately secondary to physician omission (93.7%) and were more likely to be White ( p < 0.01) and older ( p < 0.01). There was a negative relationship with physician omission over time. Conclusion: The policy was successfully implemented with decreasing proportions of patients not tested. Earlier inclusion of testing into standard admission orders and nurse-based approach may have expedited adoption. Given the low incidence of new HIV diagnosis in labor, we were unable to assess decrease in MTCT.

Published: January 2018

Background: It remains unclear whether the tibiofemoral relationship in the sagittal plane is restored after anatomic anterior cruciate ligament (ACL) reconstruction, particularly in cases of chronic ACL deficiency (ACLD). Hypothesis: Patients with long-term ACLD will exhibit an anteriorly subluxed tibia both preoperatively and immediately postoperatively, even after anatomic reconstruction. Study Design: Cohort study; Level of evidence, 2. Methods: In total, 358 patients who had undergone anatomic ACL reconstruction with autologous semitendinosus grafts were divided into 5 groups based on chronicity of ACLD: (1) 0 to 6 months, (2) 6 months to 1 year, (3) 1 to 2 years, (4) 2 to 5 years, and (5) longer than 5 years. Preoperatively and immediately postoperatively, all patients underwent lateral radiography in extension to evaluate the tibiofemoral relationship, specifically with regard to anterior tibial subluxation (ATS), space for the ACL (sACL), and extension angle. Demographic and radiographic factors were compared among the 5 groups. Results: Preoperative ATS values in groups 4 (mean ± SD, 2.9 ± 2.1 mm) and 5 (2.6 ± 1.9 mm) were significantly greater than in group 1 (1.6 ± 1.9 mm). Postoperatively, the tibia was posteriorly overconstrained in all groups, and there was no difference in immediately postoperative ATS among the 5 groups. Further evaluation of the tibiofemoral relationship in the sagittal plane revealed that the mean preoperative side-to-side difference in sACL (sACL-SSD) was greater in groups 4 (2.5 ± 1.6 mm) and 5 (2.2 ± 1.7 mm) than in group 1 (1.2 ± 1.5 mm). Immediately after ACL reconstruction, however, there were no group-dependent differences in sACL-SSD. No significant group-dependent differences were found for extension deficit. Conclusion: Chronicity of ACLD had an effect on the preoperative tibiofemoral relationship in the sagittal plane, including ATS and sACL-SSD, especially in patients with ACLD longer than 2 years. However, preoperative extension deficit was not influenced by chronicity. Immediately postoperatively, chronicity did not affect the ability of anatomic ACL reconstruction to reduce subluxation.
Professional perceptions of the effectiveness of visual communication systems and their applications for functional communication interventions for individuals with Autism Spectrum Disorder
Authors: Alexander Elizabeth , Dille Lisa 
Published: January 2018

Background & aims This study investigated the perceptions of educational professionals in regard to the effectiveness of visual communication systems and their applications as a functional communication intervention for individuals with Autism Spectrum Disorder (ASD). Methods One hundred and one individuals from diverse educational backgrounds, school districts, educational services, and various states were surveyed for this study. All participants in this study served individuals with Autism Spectrum Disorder in a clinical and/or school setting. Results The study found that aided augmentative and alternative communication (AAC) systems were widely utilized, and participants perceived these systems as the most effective for individuals with Autism Spectrum Disorder. It also found that the use of low level tech aided augmentative communication systems such as Picture Exchange System and high level tech systems such as voice output systems that were strictly computer based, were dependent on the individual's abilities and needs. Finally, the study found that the use of photography and photo journaling techniques had positive outcomes for individuals diagnosed with Autism Spectrum Disorder and other students in the learning environment. Conclusions The results revealed that the overall consensus of educational professionals that serve individuals with ASD agreed that aided AAC systems were more effective methods to foster and enhance functional communication. In terms of effectiveness of the level of technology utilized within the system, it depends on the needs and abilities of the individual with ASD. Participants, however, did agree that photography and photo journaling techniques may provide positive attributes to all students and not only those diagnosed with ASD. Implications The ability to modify or alter the ways in which AAC systems are created and implemented may address the need to individualize the systems in terms of the needs and abilities of the individual with ASD. The results inform educational practices as they highlight that a majority of the professionals that participated in this study need further professional development with the understanding and application of these systems in order to better understand their benefits and what they have to offer individuals with ASD. The results also provided a lens through the professionals' experiences into the classrooms by providing information from professionals that utilize and implement these systems daily including their successes in aiding communication effectively.

Purpose Stock outs of cancer drugs are potentially fatal but have not been systematically studied in low- and middle-income countries. The aim of this study was to determine the availability and alignment of the Botswana National Essential Medicines List (NEML) for cancer drugs with the WHO’s Essential Medicines List (EML). Methods The availability and cost of cancer drugs were analyzed using data from a weekly stock catalog sent by Botswana’s Central Medical Store to all pharmacy departments in government hospitals. Comparative data were extracted from the WHO EML and the “International Drug Price Indicator Guide-2014” from the Management Sciences for Health. Interviews with key informants were used to collect data on the Botswana NEML and the drug supply chain in the public sector. Results The 2015 Botswana NEML for cancer had 80.5% alignment with the WHO EML. At least 40% of essential drugs were out of stock for a median duration of 30 days in 2015. Stock outs affected chemotherapy drugs included in first-line regimens for treating potentially curable diseases such as cervical, breast, and colorectal cancer and were not associated with buyer price of therapy. Analyses showed that the median price ratio for procured drugs was greater than 1 for 61% of the NEML drugs, which suggests inefficiency in procurement in the public sector. Conclusions Botswana has one of the highest alignments of NEML to the WHO EML in the sub-Saharan African region, which is consistent with investment in the health care system evident in other clinical spheres. Better quantification of chemotherapy requirements using data from the National Cancer Registry and resource-sensitive treatment guidelines can help reduce stock outs and facilitate more effective and efficient procurement processes.
