The Wisdom of Thai Indigenous Healers for the Spiritual Healing of Fractures
Authors: Juntaramano Siriratana , Swangareeruk Janerawee , Khunboonchan Tanida
Published: April 2018

Aims: The aim of this study was to explore the wisdom of Thai indigenous healers (IHs) for physical and spiritual healing and their treatment process for fractures. Method: Twelve IHs from four regions of Thailand were selected using cluster and purposive sampling. They were interviewed on their methods for treating fractures. The Colaizzi method was used for analysis, and we returned to the IHs for validity confirmation. Findings: The wisdom of IHs is believed to be inherited from ancestors and from a “sixth sense,” their former teacher’s spirit. There are no textbooks, only one-on-one training. The annual Wai Khru ceremony, where IHs pay respect to their teachers, is believed to also impart a blessing of greater wisdom to the student healer. Their physical treatment of fractures is like that by an orthopedic physician, but their methods and materials are different because physical treatment is combined with spiritual care. Conclusion: Certain aspects of IH practice may have application for professional nursing. It is suggested that incorporating traditional spiritual care into nursing may improve patients’ quality of life, both physically and spiritually.
Relationship between knowledge and skills in the Nigerian undergraduate chemistry curriculum and graduate employability in chemical-based industries
Authors: Okunuga Rachael O. , Ajeyalemi Duro
Published: April 2018

The knowledge and skills required of chemists in chemical-based industries were compared to those in the undergraduate chemistry curriculum in Nigeria to establish whether there were gaps between the two. In a questionnaire survey, 120 chemists in 20 chemical-based industries gave their views of the extent to which the chemistry curriculum reflected industry needs for knowledge and skills. The data generated were analysed using means and paired sample t-tests. The results indicate that the Nigerian university chemistry curriculum is broad-based and sufficiently relevant to meet the theoretical knowledge requirements of chemical-based industries, but that it fails to meet their minimal skills requirements. While chemistry graduates have greater knowledge than is required for work in chemical-based industries, their skills level is below the industry requirement. The curriculum therefore needs to be restructured so that its skills acquisition component is improved.
Orbital transfer strategy using only-accelerating maneuvers
Authors: Luo Tong , Xu Ming
Published: April 2018

Two types of new orbital transfer strategies that use only-accelerating maneuvers are proposed for a simple spacecraft with only one engine. Based on the requirement of only-accelerating maneuvers, the constraints on the orbital parameters in the entire transfer process are derived from Gauss variational equations. The explanation of these constraints from the geometric viewpoint makes it easy to determine an initial maneuver sequence without time-consuming computation. Only-accelerating maneuvers for an orbital transfer mission can also be implemented by two different approaches: impulsive maneuvers and finite-thrust propulsive maneuvers. The algorithm to determine both maneuvers are summarized in three steps. Impulsive maneuvers can accomplish a transfer mission in an orbital period, whereas finite-thrust propulsive maneuvers require several orbital periods, but a smaller thrust. Finally, numerical simulations are conducted for their application to specific transfer missions.
Characterization of cavitation and seal damage during pump operation by vibration and motor current signal spectra
Authors: Sun Hui , Yuan Shouqi , Luo Yin
Published: April 2018

Cyclic spectral analysis is conducted to extract the frequency characteristic components from nonstationary current signals under cavitation and seal damage conditions as indicators of fault characterization. Specifically, vibration and current signals are both acquired and pre-processed by envelope extraction and singular value decomposition methods, respectively. Since there are more noise waves in vibration power spectral density spectra in comparison with current signals, the cyclic spectral analysis is conducted for the current signal analysis. Cyclic autocorrelation functions of signals are firstly calculated then corresponding slices are extracted from the cyclic autocorrelation functions and processed by fast Fourier transform method. Consequently from the spectra, indicators for characterization are extracted to demonstrate the occurrence and severity of faults. Results show that the rotating frequency component shows obvious tendency as the flow rate deviates from the designed point without any faults. The indicators for seal damage characterization are 250 Hz and 350 Hz frequency components related with rotating frequency and blade passing frequency in the current signals. Meanwhile, the occurrence and development status of cavitation are indicated by the frequency component of 100 Hz in the slice spectra of cyclic autocorrelation functions. Additionally, the effect of instability caused by off-design, seal damage, as well as cavitation operation conditions is distinguished by cyclic spectral analysis. Characteristic components are innovatively extracted at specific frequencies to avoid the effect from modulated and noise components in the current signals. And the results about the recognition of different types of faults could provide important evidences for fault detection during pump operation.
Marxism, psychoanalysis, and the critique of psychological dualism: From dualist repression to the return of the repressed in hysteria and class consciousness
Authors: Pavón-Cuéllar David
Published: April 2018

This article discusses how the psychic reality is separated from everything else in modern psychology and argues that this separation may be related to capitalism. It also explores how Marx and Freud, as well as later Marxists and Marxist Freudians, have critically examined the psyche/world and psyche/soma dichotomies. Their critique uncovered a kind of groundless dualism, which was denounced as a way of exerting power over the body and world, as a consequence of the manual/intellectual division of labour, and as the dematerialization of subjectivity by repressing and sublimating-idealizing processes. These denunciations make it possible to appreciate how Marxism and psychoanalysis—by arousing class consciousness among the labourers and by making the unconscious conscious in hysteria—allowed symptomatic disclosures of the truth of monism in the faults of a psychological dualistic knowledge.
Intentional, dual purpose of ancient wine presses as cisterns for runoff water harvesting in drylands
Authors: Stavi Ilan , Chocron Matan , Filin Sagi , Arav Reuma , Ackermann Oren , Zissu Boaz
Published: April 2018

Rock-quarried wine presses were prevalent across the Mediterranean Basin throughout ancient times and particularly during the Late Roman and Byzantine ages. Archeological surveys have uncovered many presses across Israel. Overall, a ratio of ~5 m−1 has been recorded between treading floor area (in m2) and volume of collecting vat (in m3). A recent survey of two presses located at the transition zone between the semi-arid northern Negev, Judean Lowlands, and Southern Hebron Hills of Israel revealed a considerably smaller ratio between the treading floor and collecting vat. In addition, extensive rock exposures were located around the treading floors of the two presses. A 3D laser scanning revealed that the surrounding rock exposure formed a drainage network which flows to the treading floor. Moreover, indications for light modifications of the surrounding rock exposure were recorded for the two presses. In one of the presses, this modification was indicated by remnants of ancient plaster, which were found filling several gaps in the surrounding rock exposure. It is suggested that the purpose of the plaster was for allowing hydrological connectivity between the upslope and downslope edges of these gaps. In the second press, this modification included the chiseling of adjacent bedrock, for the purpose of, it is suggested, channeling runoff water to the treading floor. The findings suggest the intentional collection of raindrops falling on the surrounding rock exposure, together with those falling on the treading floor, which were drained as runoff into the collecting vat. The collected runoff could be used for domestic consumption in this dryland region, augmenting the provision of water for the local populations during the agricultural off-season.
The Impact of Work–Family Issues on Turnover Intentions among Nurses? A Study from North-eastern India
Authors: Rajkonwar Bubbly , Rastogi Mansi
Published: April 2018

The aim of this article is to identify the effects of work–family interface on turnover intentions (TIs) for nurses in public and private hospitals in the Assam region of India. Thus, this study intends to examine the impact of work–family enrichment (WFE) and conflict on TIs among nursing staff. One structured questionnaire was administered to nurses of public and private hospitals located in Guwahati, Barpeta, Dhemaji, Lakhimpur, Tezpur, Jorhat, Dibrugarh, Tinsukia, Duliajan and Silchar regions of Assam, India Republic. The data were analysed using Statistical Package for Social Sciences version 23. Results indicated significant positive relationship between work–family conflict (WFC) and TIs of nurses. On the other hand, findings revealed that WFE also influences TIs but negatively. Thus, both proposed hypotheses were accepted. Implications, contributions and limitations are discussed. Recommendations are made for future work directions.

Published: April 2018

Trauma-informed care (TIC) is a widely adopted organizational approach to health and human services. The current study occurred within a residential addiction treatment agency and has two aims: To operationalize the processes, an agency can take to become trauma informed and assesses the impact of a multiyear TIC implementation project on organizational climate, procedures, staff and resident satisfaction, and client retention in treatment. Pearson χ2 tests were computed to assess variation in client satisfaction and discharge status, while climate, procedures, and staff satisfaction were assessed by effect size differences. Following TIC implementation, there were positive changes in each of the five outcomes assessed. Workplace satisfaction, climate, and procedures improved by moderate to large effect sizes, while client satisfaction and the number of planned discharges improved significantly. The current study provides support for implementing TIC. Future research may continue to examine the influence of TIC implementation.
Parental Experiences of Child Participation in a Phase I Pediatric Oncology Clinical Trial: “We Don’t Have Time to Waste”
Authors: Crane Stacey , Haase Joan E. , Hickman Susan E.
Published: April 2018

Children with cancer are only eligible for phase I clinical trials (P1Ts) when no known curative therapy remains. However, the primary aims of P1Ts are not focused on directly benefiting participants. This raises ethical concerns that can be best evaluated by exploring the experiences of participants. An empirical phenomenology study, using an adapted Colaizzi method, was conducted of 11 parents’ lived experiences of their child’s participation in a pediatric oncology P1T. Study findings were that parents’ experiences reflected what it meant to have a child fighting to survive high-risk cancer. Although elements specific to P1T participation were identified, more pervasive was parents’ sense of running out of time to find an effective treatment and needing to use time they had with their child well. Even though some problems were identified, overall parents did not regret their child’s P1T participation and would recommend P1Ts to other parents of children with cancer.
The Pink Underside: The Commercialization of Medical Risk Assessment and Decision-Making Tools for Hereditary Breast Cancer Risk
Authors: Hesse-Biber Sharlene , Flynn Bailey , Farrelly Keeva
Published: April 2018

The growth of the Internet since the millennium has opened up a myriad of opportunities for education, particularly in medicine. Although those looking for health care information used to have to turn to a face-to-face doctor’s visit, an immense library of medical advice is now available at their fingertips. The BRCA genetic predispositions (mutations of the BRCA1 and BRCA2 breast cancer genes) which expose men and women to greater risk of breast, ovarian, and other cancers can be researched extensively online. Several nonprofit organizations now offer online risk assessment and decision-making tools meant to supplement conversation with medical professionals, which in actuality are quickly replacing it. We argue here through a critical qualitative template analysis of several such tools that the discursive frameworks utilized are prone to fearmongering, commercialization, and questionable validity. Left unchecked, these assessment tools could do more harm than good in driving young women especially to take unnecessary extreme surgical action.
Autogenous Bone Graft Versus Bovine Bone Graft in Association With Platelet-Rich Plasma for the Reconstruction of Alveolar Clefts: A Pilot Study
Authors: Bezerra Bruno Torres , Pinho John Nadson Andrade , Figueiredo Fabrício Eneas Diniz , Brandão José Renato Moraes Carvalho Barreto , Ayres Lucas Celestino Guerzet , da Silva Luiz Carlos Ferreira
Published: April 2018

Objective:

To compare the outcomes of 2 different bone graft materials: autogenous bone grafts from mandibular symphysis and bovine bone grafts associated with platelet-rich plasma (PRP).

Methods:

Twenty individuals met the inclusion criteria and accepted to participate in the study. Group A patients underwent alveolar bone grafting using autologous bone and group B patients using a bovine bone graft associated with PRP. Cone beam computed tomography scans were taken and reconstructed 3-dimensionally for all patients preoperatively and 1 year postoperatively.

Results:

A significant reduction was detected for area and volume within group A and group B. Between groups, no significant difference was found for area or volume.

Conclusions:

Bovine grafts associated with PRP are a good option for the reconstruction of alveolar clefts and provide good results such as autologous bone grafts.
Subsegmental Osteotomy Technique With Distraction Osteogenesis for Natural Frontal Contouring in Metopic Synostosis
Authors: Han Kihwan , Jeong Woonhyeok , Kim Jinhan , Oh Sangho
Published: April 2018

Vectoring issues occur due to the dynamics of unidirectional procedure that is selected. To circumvent such difficulties, we have devised subsegmental osteotomy with distraction. In our technique, frontal bone flap was divided into 4 segments that were linked to each other by suturing wires in an 8-year-old patient with trigonocephaly. Subsegmental osteotomy and wiring of bone flap enabled us to slide bone in a more curvilinear manner and achieve natural contour. Distraction was initiated on postoperative day 7 at the rate of 1 mm/d for 20-mm gain. At the 9-year follow-up, the patient showed improved head shape and intellectual status.
Psychotropic Pharmacotherapy Associated With QT Prolongation Among Veterans With Posttraumatic Stress Disorder
Authors: Stock Eileen M. , Zeber John E. , McNeal Catherine J. , Banchs Javier E. , Copeland Laurel A.
Published: April 2018

Background: In 2012, the Food and Drug Administration issued Drug Safety Communications on several drugs associated with QT prolongation and fatal ventricular arrhythmias. Among these was citalopram, a selective serotonin reuptake inhibitor (SSRI) approved for depression and commonly used for posttraumatic stress disorder (PTSD). Evaluation of the risk for QT prolongation among other psychotropic drugs for individuals with PTSD remains limited. Objective: Explore psychotropic drugs associated with QT prolongation among veterans with PTSD. Methods: Patients in the Veterans Health Administration in 2006-2009 with PTSD and QT prolongation (176 cases) were matched 1:4 on age, gender, visit date and setting, and physical comorbidity. Classification trees assessed QT prolongation risk among prescribed medications (n=880). Results: Receipt of any drug with known risk of QT prolongation varied by group (23% QT cases vs 15% control, p<0.01). Psychotropic medications conferring significant risks included ziprasidone (3% vs 1%, p=0.02) and buspirone (6% vs 2%, p=0.01). Increased risk was not observed for the SSRIs, citalopram and fluoxetine. Classification trees found that sotalol and amitriptyline carried greater risk among cardiac patients and methadone, especially if prescribed with quetiapine, among noncardiac patients. Per adjusted survival model, patients with QT prolongation were at increased risk for death (hazard ratio=1.60; 95% CI=1.04-2.44). Conclusions: Decision models are particularly advantageous when exploring nonlinear relationships or nonadditive interactions. These findings may potentially affect clinical decision-making concerning treatment for PTSD. For patients at higher risk of QT prolongation, antidepressants other than amitriptyline should be considered. Medications for comorbid conditions should also be closely monitored for heightened QT prolongation risk.
Impact of Pharmacist-Physician Collaboration on Osteoporosis Treatment Rates
Authors: Bowers Brandi L. , Drew Amy M. , Verry Christian
Published: April 2018

Background: The vast majority of women at high risk for osteoporotic fractures are not treated, despite known significant clinical and economic consequences of this prevalent condition. To date, this is the first study of this size and duration to examine the role of pharmacists in management of osteoporosis in a family medicine clinic. Objective: To compare the initiation or continuation of prescription antifracture therapy in high-risk patients with collaborative pharmacist-physician to physician-only management; secondarily, to evaluate recommendation rates for antifracture therapy and calcium and vitamin D. Methods: This retrospective cohort analysis included women older than 65 years with a dual-energy X-ray absorptiometry (DXA) scan ordered by a family medicine physician. High risk was defined as T-scores ≤−2.5 at the lumbar spine, femoral neck, or 33% radius, or a FRAX 10-year fracture risk score ≥20% for major osteoporosis-related or ≥3% for hip fractures. Results: There were 466 (311 high-risk) pharmacist-physician and 549 (237 high-risk) physician-managed DXAs included. For high-risk DXAs, collaborative management resulted in increased rates of receiving antifracture therapy prescriptions over physician-only management (66% vs 34%, P < 0.001), advisement for antifracture therapy (87% vs 32%, P < 0.001), and calcium and vitamin D (97% vs 45%, P < 0.001). Collaborative management also improved calcium and vitamin D advisement among all DXAs (96% vs 46%, P < 0.01). There was no difference in adverse events documented in the pharmacist-physician compared with physician-only management (7.2% vs 3.7%, P = 0.32). Conclusion and Relevance: Pharmacist-physician collaboration is associated with higher treatment rates of osteoporosis. This study supports the pharmacist-physician partnership as one method of improving osteoporosis management.
Comparing Climate Policy Processes in India, Brazil, and South Africa: Domestic Engagements With International Climate Policy Frameworks
Authors: Upadhyaya Prabhat , Fridahl Mathias , Linnér Björn-Ola , Román Mikael
Published: April 2018

Using policy cycle model as a heuristic, this article studies Indian, Brazilian, and South African engagement with Nationally Appropriate Mitigation Actions (NAMAs) by (a) comparing NAMA policy process and (b) identifying factors driving or limiting the framework’s domestic application. India largely remained uninterested in NAMAs, Brazil aligned its domestic climate policy and NAMAs, while South Africa had a more nuanced engagement when formulating NAMAs. Four factors influenced these countries’ NAMA engagements: the level and necessity of international support, the availability of domestic policy provisions to tackle climate change, the domestic institutional capacity to coordinate interministerial functioning, and the role of individuals in the institutional apparatus. As an international climate policy framework, studying NAMA engagement provides learnings for nationally determined contributions under the Paris Agreement for designing the instrument, ensuring clarity on support provisions for ratcheting up ambitions, and enhancing institutional capacity, to expedite transition from policy formulation to implementation and beyond.
Patient-Reported Allergies Do Not Predict Poorer PROMIS Function, Pain, and Depression Scores Following Foot and Ankle Surgery
Authors: Nixon Devon C. , Cusworth Brian M. , McCormick Jeremy J. , Johnson Jeffrey E. , Klein Sandra E.
Published: April 2018

Background:

Identifying preoperative risk factors that may portend poorer operative outcomes remains a topic of current interest. In hip and knee arthroplasty patients, the presence of patient-reported allergies (PRAs) has been associated with worse pain and function after joint replacement. However, these results have not been replicated across studies, including in shoulder arthroplasty cases. The impact of PRAs on foot and ankle outcomes has yet to be studied. The purpose of our study was to evaluate whether PRAs influence patient-reported outcome in foot and ankle surgery.

Methods:

To determine if PRAs are linked to poorer operative outcomes, we retrospectively identified 159 patients who underwent elective foot and ankle surgery. PRA data were obtained via chart review, and patient-reported outcomes were assessed preoperatively and postoperatively via multiple domains, including Patient Reported Outcome Measurement Information System (PROMIS) physical function, pain interference, and depression measures. Consistent with prior methodology, we compared outcome measures (preoperative, postoperative, and the change in outcome scores) between patients without self-reported allergies to patients with at least 1 PRA.

Results:

There were 159 patients studied; 79 patients had no allergies listed, and 80 patients had at least 1 PRA. Of the 80 patients with at least 1 PRA, there were a total of 170 possible allergies. There were no differences in preoperative, postoperative, or the change in outcome scores for all PROMIS measures (physical function, pain interference, and depression; P > .05) between patients with at least 1 PRA and those patients without any listed PRAs.

Conclusions:

We were unable to prove our hypothesis that PRAs were linked to poorer patient-reported outcomes following foot and ankle surgery. Closer review of the published reports linking PRAs to worse total joint arthroplasty outcomes revealed data that, while statistically significant, are likely not clinically relevant. Our negative findings, then, may in fact parallel prior studies on hip, knee, and shoulder arthroplasty patients. The presence of PRAs does not appear to be a risk factor for suboptimal outcomes in foot and ankle surgery.

Beyond Mapping: Seizing Affective Geographies in Toronto
Authors: Buiani Roberta
Published: April 2018

In this article, I use a recent research creation project and its mobile component (the TiP lab) to emphasize the importance of regarding the city as an entanglement of sometimes evident, sometimes hidden naturecultural geographies and more-than-human encounters. While official narratives are not interested in narrating such vibrant multidimensionality, traditional cartographic practices do not seem to be able to seize them. In exploring ways to illuminate such complexity, I interrogate the ability of contemporary mapping devices to capture, and valorize, the vectors through which the human and the nonhuman, people and infrastructures shape the urban landscapes in which they live and through which they pass.
New versus old: Implications of evolving diagnostic criteria for relapsing–remitting multiple sclerosis
Authors: McNicholas Nuala , Lockhart Andrew , Yap Siew M , O’Connell Karen , Tubridy Niall , Hutchinson Michael , McGuigan Christopher
Published: April 2018

The International Panel on Diagnosis of Multiple Sclerosis (MS) recently revised the 2010 McDonald criteria and made recommendations for revision, allowing for the earliest possible, accurate diagnosis of MS. For relapsing–remitting MS, positive, unmatched cerebrospinal fluid oligoclonal bands may substitute for dissemination in time. Symptomatic lesions, including brainstem and spinal cord, may demonstrate dissemination in space or in time if enhancing (with the exception of the optic nerve). Cortical and juxtacortical lesions are equivalent. In this retrospective analysis, we applied revised criteria to 250 patients previously diagnosed with relapsing–remitting MS according to 2010 criteria and assessed for change in diagnostic times. There was a significant improvement in time to diagnosis between 2010 and 2017 groups ( p < 0.01). Median time to diagnosis according to McDonald 2010 was 7.4 months, compared with 2.3 months for McDonald 2017. Use of cerebrospinal fluid results most frequently resulted in a reduction in time to diagnosis. Symptomatic gadolinium-enhancing lesions led to earliest diagnostic times.
Longitudinal prospective associations between psychological symptoms and heavy episodic drinking from adolescence to midlife

Published: April 2018

Aim: This study examined whether development of psychological symptoms (PS) differed between persons with different longitudinal profiles of heavy episodic drinking (HED) from adolescence to midlife. In addition, the reciprocal associations between PS and HED were studied. Methods: Participants of a Finnish cohort study in 1983 at age 16 ( N = 2194) were followed up at ages 22 ( N = 1656), 32 ( N = 1471), and 42 ( N = 1334). HED was assessed with frequency of intoxication (16–22 years) and having six or more drinks in a session (32–42 years). Using latent class analysis, the participants were allocated to steady high, increased, moderate, and steady low groups according to their longitudinal profiles of HED. The PS scale (16–42 years) covered five mental complaints. The latent growth curve of PS was estimated in the HED groups for comparisons. In addition, the prospective associations between symptoms and HED were examined using cross-lagged autoregressive models. Results: PS grew from 16 to 32 years, but declined after that, with women having higher level of PS than men. PS trajectory followed a path at highest and lowest level in the steady high and steady low HED groups, respectively. Symptoms predicted later HED, but the association in the opposite direction was not found. Conclusions: The more the HED trajectory indicated frequent HED, the higher was the level of PS throughout the follow-up. Results support the self-medication hypothesis, suggesting that alcohol is used to ease the burden of PS. More attention should be paid to alcohol use of people with mental symptoms in health services.
‘Manly tears exploded from my eyes, lets feel together brahs’: Emotion and masculinity within an online body building community
Authors: Underwood Mair , Olson Rebecca
Published: April 2018

Discussions of crying and love are not what one might expect to find when examining interactions between recreational bodybuilders online. Gendered emotion ideologies, especially related to muscular masculinities, usually forbid men from exhibiting emotional vulnerability in front of other men, as emotional detachment is one of the ways gender hierarchies are maintained. Building on Connell’s concept of ‘hegemonic masculinity’ and Hochschild’s concept of ‘emotion management’, this article analyses emotional exchanges within an international community of male recreational bodybuilders: fans of Aziz Shavershian, known as ‘Zyzz’. We examine the meaning of emotions within the Zyzz fandom’s local hierarchy of masculinities, the expressive freedoms afforded by the context of their emotional interactions, and the strategies employed by Zyzz and fans to traverse masculine emotion ideologies that usually prevent men from expressing love and affection.
#Votebecause: Youth mobilisation for the referendum on British membership of the European Union
Authors: Sloam James
Published: April 2018

For several decades, academics and political commentators have lamented the decline in electoral participation among younger citizens. In the United Kingdom, the proportion of 18- to 24-year-olds voting in general elections fell from over 60% in 1992 to an average of 40% between 2001 and 2015. Nevertheless, the high youth turnout in 2017 showed that young people will vote if they are interested in an issue or cause. Despite the scholarly interest in youth turnout, few studies have investigated the individual motivations for electoral participation among young people. This article aims to fill this gap. It presents a qualitative analysis of ‘#Votebecause’, an offline–online initiative to encourage students to vote in the 2016 referendum on British membership of the European Union. The findings identify the importance of social networks, appropriate spaces for communication, deliberation, prior group membership and internal efficacy for engaging young people in the campaign.
Visuality, text and talk, and the systematic organization of interaction in Periscope live video streams
Authors: Licoppe Christian , Morel Julien
Published: April 2018

In this study, we use a conversation analysis framework to understand the systematic organization of interactions in Periscope live video streams, and its crucial features: (a) the talking heads orientation for the video stream, in common with video-mediated communication; (b) the expectation that the streamer should attend to all messages as much as possible; (c) the ‘loose’ organization of viewers’ responses to streamers’ turn-at-talk, as in multi-party chats. We also identify a distinctive design for streamers’ responses to messages, the ‘read-aloud and respond’ practice. These distinctive features are oriented to the highly asymmetrical communicative affordances of Periscope streams. Without precluding other forms of Periscope-based activities, this systematic organization of talk and messages, coupled with the affordances of the application, favors a basic mode of topic initiation resting on a typical and minimal adjacent pair: viewer’s noticing/streamers’ reading and responding. We argue that the particular salience of this organization of topic initiation may account for the emergence of the dominant kind of use for Periscope streams, that is, the online public exposure of youth to strangers in order to elicit some conversation.
School Subject Community in Times of Death of the Subject
Authors: Lopes Alice Casimiro , Costa Hugo Heleno Camilo
Published: April 2018

In this article, we aim to theorize about the understanding of a school subject community in a discursive framework, particularly concerned with the theoretical and strategic possibilities of this notion in the research of curriculum policy. In these times, in which the death of the centered, conscious and cohesive Subject is assumed, what precisely do we mean by subjectivity (collective or not) when we are talking about a school subject community? Goodson’s theory, in relation to structural concerns, organized socio-historical conditions to explain these phenomena. Therefore, we consider it relevant to reconceptualize Goodson´s school subject community category, or even enact its deconstruction, to the extent that we propose to include other subjectivity senses through post-structural theory. We point out that our distance from Goodson´s reading of ‘community’ takes place, also, due our distance from the assumption of the existence of common, positive data, capable of generating cohesion and/or unity among individuals. Hence, with our perspective directed towards subjectivity in the context of post-structural and political-curricular thinking, based on Laclau’s theory of discourse, we discuss the possibility of thinking about the subjectivity of a community, in this case the school subject community, or its subjectivations. In conclusion, the school subject community is the result – albeit precarious, temporary and contingent – of discursive articulation. The school subject community, through the argument we have built, is the set of subjectivities formed in provisional operations in the discursive field named school subject.
Adapting a Sexually Transmitted Infection Prevention Intervention Among Female Adolescents in Hawai‘i
Authors: Takishima-Lacasa Julie Y. , Kameoka Velma A.
Published: April 2018

Epidemiological data suggest that Native Hawaiian, Pacific Islander, and Asian American (NHPIA) adolescent females in Hawai‘i are at elevated risk for sexually transmitted infections (STIs). These data also indicate that teen girls in Hawai‘i are more likely to engage in high-risk sexual behaviors than boys. Despite this compelling evidence, there is a paucity of published research on effective STI prevention protocols that target NHPIA female adolescents. In light of this need, the purpose of this study was to adapt an evidence-based, group-level STI behavioral prevention intervention targeting local NHPIA adolescent girls in Hawai‘i for implementation by community-based organizations (CBOs). This article describes the adaptation of an evidence-based STI prevention intervention in partnership with a CBO, using a locally modified ADAPT-ITT model as a basis for the adaptation process. This research consisted of two phases: (1) development of an initial test version of an adapted intervention and (2) the development of the final version of the adapted intervention, Girl Power Hawai‘i. The results provide the empirical and foundational research necessary for a tailored intervention that can be readily implemented by CBOs for local teen girls in Hawai‘i.

Published: April 2018

Cervical cancer is the leading cause of death with gynecological malignancies. We aimed to explore the molecular mechanism of carcinogenesis and biomarkers for cervical cancer by integrated bioinformatic analysis. We employed RNA-sequencing details of 254 cervical squamous cell carcinomas and 3 normal samples from The Cancer Genome Atlas. To explore the distinct pathways, messenger RNA expression was submitted to a Gene Set Enrichment Analysis. Kyoto Encyclopedia of Genes and Genomes and protein–protein interaction network analysis of differentially expressed genes were performed. Then, we conducted pathway enrichment analysis for modules acquired in protein–protein interaction analysis and obtained a list of pathways in every module. After intersecting the results from the 3 approaches, we evaluated the survival rates of both mutual pathways and genes in the pathway, and 5 survival-related genes were obtained. Finally, Cox hazards ratio analysis of these 5 genes was performed. DNA replication pathway ( P < .001; 12 genes included) was suggested to have the strongest association with the prognosis of cervical squamous cancer. In total, 5 of the 12 genes, namely, minichromosome maintenance 2, minichromosome maintenance 4, minichromosome maintenance 5, proliferating cell nuclear antigen, and ribonuclease H2 subunit A were significantly correlated with survival. Minichromosome maintenance 5 was shown as an independent prognostic biomarker for patients with cervical cancer. This study identified a distinct pathway (DNA replication). Five genes which may be prognostic biomarkers and minichromosome maintenance 5 were identified as independent prognostic biomarkers for patients with cervical cancer.

Published: April 2018

This study aimed to evaluate both the short- and long-term efficacies of chemoradiotherapy in relation to the treatment of esophageal cancer . This was achieved through the use of dynamic contrast-enhanced magnetic resonance imaging–derived volume transfer constant and diffusion weighted imaging–derived apparent diffusion coefficient . Patients with esophageal cancer were assigned into the sensitive and resistant groups based on respective efficacies in chemoradiotherapy. Dynamic contrast-enhanced magnetic resonance imaging and diffusion weighted imaging were used to measure volume transfer constant and apparent diffusion coefficient, while computed tomography was used to calculate tumor size reduction rate. Pearson correlation analyses were conducted to analyze correlation between volume transfer constant, apparent diffusion coefficient, and the tumor size reduction rate. Receiver operating characteristic curve was constructed to analyze the short-term efficacy of volume transfer constant and apparent diffusion coefficient, while Kaplan-Meier curve was employed for survival rate analysis. Cox proportional hazard model was used for the risk factors for prognosis of patients with esophageal cancer. Our results indicated reduced levels of volume transfer constant, while increased levels were observed in ADCmin, ADCmean, and ADCmax following chemoradiotherapy. A negative correlation was determined between ADCmin, ADCmean, and ADCmax, as well as in the tumor size reduction rate prior to chemoradiotherapy, whereas a positive correlation was uncovered postchemoradiotherapy. Volume transfer constant was positively correlated with tumor size reduction rate both before and after chemoradiotherapy. The 5-year survival rate of patients with esophageal cancer having high ADCmin, ADCmean, and ADCmax and volume transfer constant before chemoradiotherapy was greater than those with respectively lower values. According to the Cox proportional hazard model, ADCmean, clinical stage, degree of differentiation, and tumor stage were all confirmed as being independent risk factors in regard to the prognosis of patients with EC. The findings of this study provide evidence suggesting that volume transfer constant and apparent diffusion coefficient as being tools allowing for the evaluation of both the short- and long-term efficacies of chemoradiotherapy esophageal cancer treatment.

This study examined the use of potentially inappropriate medicines that may affect cognition (PIMcog) in people with dementia and its associated factors. Medical records of all outpatients with dementia attending a tertiary hospital in Vietnam between January 1, 2015, and December 31, 2016, were examined. Medicine use was assessed against a list of PIMcog. Variables associated with having a PIMcog were assessed using a multiple logistic regression. Of the 128 patients, 41% used a PIMcog, 39.1% used cholinesterase inhibitors (CEIs) concomitantly with anticholinergics, and 18% used antipsychotics. The number of hospital visits (adjusted odds ratio [OR]: 1.08; 95% confidence interval [CI]: 1.02-1.16) and number of treating specialists (adjusted OR: 0.61; 95% CI: 0.45-0.83) were associated with PIMcog use. This study highlights a high-level use of medicines that can further impair cognition or reduce the effectiveness of CEIs in people with dementia. Efforts to improve quality use of medicines for this population are warranted.
Transcranial Doppler for Eagle Syndrome: Rare Presentation of Unilateral Internal Carotid Artery Compression by the Stylohyoid Ligament With Provocative Maneuvers

Published: April 2018

Eagle syndrome is a rare condition caused by compression of the internal carotid artery (ICA) or cranial nerves by an elongated styloid process or calcified stylohyoid ligament. This patient is a 56 year-old woman who presented with episodes of positional syncope for 8 years. Transcranial Doppler (TCD) demonstrated abnormally decreased flow in the left middle cerebral artery (MCA) during the syncopal episodes. The patient was evaluated by TCD, transcranial imaging (TCI), and carotid duplex (CD). First, a baseline CD and TCI were performed with the patient in a neutral position. TCD was then used during symptomatic provocative maneuvers to monitor the bilateral MCAs. Intraoperative TCD monitoring was also done during bilateral stylohyoid ligament resection, and postoperatively during the same provocative maneuvers.

The baseline CD examination revealed normal extracranial carotid anatomy; TCD and TCI showed normal mean velocities and a normal anatomic variant of fetal origin of the left posterior cerebral artery. During provocative maneuvers, TCD showed abnormally dampened to absent flow in the left MCA, consistent with compression of the left extracranial ICA. CT scan confirmed elongated stylohyoid ligaments bilaterally. The MCA mean velocities were monitored intraoperatively and postoperatively by TCD and showed no changes with head positioning immediately following resection of the stylohyoid ligaments. The patient reported no syncopal episodes at follow-up 6 days after surgery. Although rare, Eagle syndrome should be considered as a cause of positional syncope. TCD can serve as a diagnostic test, an intraoperative monitoring tool, and a method for documenting the surgical outcome.
Vasa Vasorum in Deep Vein Thrombus Recanalization
Authors: Noh Cassey Y.
Published: April 2018

Vasa vasorum is a microvessel known as “the vessel of the vessels.” It is found in tunica media in the wall of blood vessels. It is normally not visualized due to its microscopic structure, but when enough extra pressure compresses the wall of a blood vessel, by the presence of an acute thrombus for an example, this microvessel can be visualized. This case study explains how to identify vasa vasorum by analyzing Doppler waveforms. Furthermore, this case study suggests that the appearance of vasa vasorum in the 3-month follow-up may indicate that the overall recanalization of a thrombus may be more complex than how it is suggested in a published case study by Brandao and his colleagues.

Published: April 2018

The 21st century has given rise to gaming industry technologies that drive a new type of learner in the classroom. This article draws data from four case studies that were conducted as part of a sequential mixed-model study. The study explored the 21st-century skills students reported learning through their video game consumption and creation of intellectual property. The qualitative data analysis led to the development of five major findings: (1) the strategist: accomplishing the mission, (2) the creator: the art of gameplay, (3) the communicator: building relationships and communities, (4) the hero: to be the hero of a great adventure, and (5) I am an “elite”: a digital native. These findings attempt to create a profile of the 21st-century classroom gamer based on the data. They represent and support research trends that explore the gaming phenomenon, gamer traits, and 21st-century skills learned through playing video games.

Objective

This study aims to present the early results of a retrospective study of the use of novel n-butyl-2-cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins.

Methods

Patients with lower limb venous insufficiency were treated with n-butyl-2-cyanoacrylate (VenaBlock Venous Closure System) between April 2016 and July 2016. The study enrolled adults aged 21–70 years with symptomatic moderate to severe varicosities (C2–C4b) and great saphenous vein reflux lasting longer than 0.5 s with great saphenous vein diameter between 5.5 and 15 mm assessed in the standing position. No compression stockings were used after the procedure. Duplex ultrasound imaging and clinical follow-up were performed on the third day, first month, sixth month, and 12th month. Clinical, etiological, anatomical, pathophysiological classification; venous clinical severity score; and completed Aberdeen varicose vein questionnaire were recorded.

Results

Five hundred thirty-eight patients with great saphenous vein incompetency underwent n-butyl-2-cyanoacrylate ablation. The mean ablation length was 25.69 ± 4.8 cm, and the average amount of n-butyl-2-cyanoacrylate delivered was 0.87 ± 0.15 ml. The mean procedure time was 11.7 ± 4.9 min. Procedural success was 100%, and complete occlusion was observed after treatment and at the third-day follow-up. We observed ecchymosis in five patients (1.00%) at the entry site at the third-day follow-up. Phlebitis was encountered with six (1.20%) patients. No skin pigmentation, hematoma, paresthesia, deep vein thrombosis, or pulmonary embolism was observed. Kaplan–Meier analysis yielded an occlusion rate of 99.4% at the 12-month follow-up. All patients had significant improvement in venous clinical severity score and Aberdeen varicose vein questionnaire scores postoperatively ( p <0.0001). Venous clinical severity score scores decreased from 5.43 ± 0.87 to 0.6 ± 0.75. Aberdeen varicose vein questionnaire scores decreased from 18.32 ± 5.24 to 4.61 ± 1.42.

Conclusions

The procedure appears to be feasible, safe, and efficient in treating the great majority of incompetent great saphenous veins with this technique.
