“…Love Me”: A Found Poem Exploring Black Women’s Romantic Relationships
Authors: Cutts Qiana M.
Published: November 2018

A found poem from a phenomenological exploration of Black women’s romantic relationship narratives and the author’s reflexive notes is presented. Drawing from Monica Prendergast’s vox autobiographia/autoethnographia and vox participare, the author considers the poem an autobiographia vox participare as it was sculpted from merging participants’ voices and the author’s personal reflections. In sculpting the poem, the author was attentive to craft and aesthetics but prioritized emotion and mending by selecting words and phrases to highlight the intensity of the experiences and sectioning the poem to represent BREATH-ing (i.e., balancing, reflection, energy, association, transparency, healing, and empowerment) as a healing process.

Authors: Reyes Maria M. , Schneekloth Terry D. , Hitschfeld Mario J. , Karpyak Victor M.
Published: November 2018

Objective: To assess for intrasex and intersex differences in psychiatric comorbidity according to ADHD status in treatment-seeking adults with alcohol use disorders (AUDs). Method: This study was a secondary analysis of data utilizing descriptive statistics from 472 treatment-seeking alcoholics who completed the Psychiatric Research Interview for Substance and Mental Disorders (PRISM). Results: The prevalence of ADHD in males and females was 6.0% and 6.4%, respectively. Males with ADHD and AUDs had higher rates of current and lifetime drug use disorders, current depressive disorders, and current and lifetime anxiety disorders than male alcoholics without ADHD. No intrasex differences in psychiatric comorbidities were identified in female alcoholics with respect to ADHD status. Males with ADHD and AUDs were more likely to have had opioid dependence than ADHD-positive females. No other intersex differences were found. Conclusion: Positive ADHD status was associated with increased psychiatric comorbidity among treatment-seeking alcoholic men.
Procrastination of Travel: The Effect of Crowdedness
Authors: Wang Yuan , Li Xiang (Robert)
Published: November 2018

The tendency to postpone an action, otherwise known as procrastination, is related to the discounting of future costs. In a tourism context, despite having the best intentions to travel, people may procrastinate their trips. Considering crowding as a type of travel cost, this study examined the effects of crowdedness on travelers’ intentions to visit a theme park and their intended timing of the visit. The results of binomial logistic regression models reveal that crowdedness is negatively related to tourists’ theme park visit intention. More important, crowding is associated with people’s procrastination on their specific timing of visiting the theme park. By focusing on the effect of travel cost (i.e., crowding) on procrastination, this paper calls for more attention to procrastination in the travel and tourism industry and proposes procrastination as a different angle to look at the nontravel phenomenon.
Residents’ lamp purchasing behaviour, indoor lighting characteristics and choices in Swedish homes
Authors: Gerhardsson Kiran M. , Laike Thorbjörn , Johansson Maria
Published: November 2018

Indoor lighting is known to affect people’s wellbeing, mood and behaviour. The rapid development of new energy-efficient lamp technologies has enabled new lighting applications in home environments. To investigate the prospects of introducing a personalised light emitting diode (LED)-based home lighting technology, a mixed-methods research study was carried out, applying the goal-framing theory. The results, based on a questionnaire survey ( N = 536), show that purchasing costs of energy-efficient lamps have little effect on consumers’ lamp choices, and that the degree of consumer acceptance of LED lamps has increased in recent years without resulting in increased lighting use. The results confirm that Swedish homes are characterised by many lamps, an average of 39 per home, but there is a significant variation across tenure type. Based on a qualitative analysis of interviews with 12 participants, the conclusion can be drawn that residents seem to know what kind of lighting they want, but they do not necessarily have what they want for a variety of reasons. Besides individual characteristics, situational factors influence residents’ home lighting and visual comfort, such as the indoor built home environment and the availability of lighting products. Consequently, responsibility for residents’ actual home lighting also lies with housing developers, lighting producers and providers.

Authors: Chang Yue , Hou Kang , Li Xuxiang , Zhang Yue
Published: November 2018

This study analysed the dynamic changes and driving forces in the urbanization from 1997 to 2016 of Xixian, a national new development area in Xi’an City, by using geographical information systems and remote sensing. The results showed that farmland was the main land use type from 1997 to 2004. However, the construction land occupied the largest area from 2011 to 2016. There was a significant expansion in the construction land area (33.24%), unused land (91.10%) and woodland (37.59%) from 1997 to 2016. In addition, in the period from 1997 to 2016, the water body, grassland and farmland were reduced by 52.52%, 31.73% and 23.84%, respectively. The increasing area of construction land was the inevitable result of urbanization. The terrain, policy and geographical location factors are the main driving forces for changes in the land use and urbanization. The planning of Xixian National New Area’s building environment should be linked and connected with the Xi’an main districts. The findings confirmed the applicability and effectiveness of the combined method of geographical information systems and remote sensing for revealing the notable spatio-temporal features in the dynamic changes in the land use and land cover throughout different time periods of Xixian.
An adaptive sliding mode controller for the lateral control of articulated long vehicles
Authors: Esmaeili Naser , Kazemi Reza , Tabatabaei Oreh S Hamed
Published: November 2018

Today, use of articulated long vehicles is surging. The advantages of using large articulated vehicles are that fewer drivers are used and fuel consumption decreases significantly. The major problem of these vehicles is inappropriate lateral performance at high speed. The articulated long vehicle discussed in this article consists of tractor and two semi-trailer units that widely used to carry goods. The main purpose of this article is to design an adaptive sliding mode controller that is resistant to changing the load of trailers and measuring the noise of the sensors. Control variables are considered as yaw rate and lateral velocity of tractor and also first and second articulation angles. These four variables are regulated by steering the axles of the articulated vehicle. In this article after developing and verifying the dynamic model, a new adaptive sliding mode controller is designed on the basis of a nonlinear model. This new adaptive sliding mode controller steers the axles of the tractor and trailers through estimation of mass and moment of inertia of the trailers to maintain the stability of the vehicle. An articulated vehicle has been exposed to a lane change maneuver based on the trailer load in three different modes (low, medium and high load) and on a dry and wet road. Simulation results demonstrate the efficiency of this controller to maintain the stability of this articulated vehicle in a low-speed steep steer and high-speed lane change maneuvers. Finally, the robustness of this controller has been shown in the presence of measurement noise of the sensors. In fact, the main innovation of this article is in the designing of an adaptive sliding mode controller, which by changing the load of the trailers, in high-speed and low-speed maneuvers and in dry and wet roads, has the best performance compared to conventional sliding mode and linear controllers.
Development of a coupled numerical model for the interaction between transient fluid slosh and tank wagon vibration
Authors: Rahmati-Alaei Ahmad , Sharavi Majid , Samadian Zakaria Masoud
Published: November 2018

In this paper, a coupled model is developed to evaluate the effect of transient fluid slosh on the railway tank wagon dynamic vice versa. This model has computational complexity in solving the Navier–Stokes equations and nonlinear differential equations of tank wagon vibration with nonlinear wheel–rail contact. The coupled model can be used as an effective and robust tool compared to simplified models for assessing the stability of tank wagon. The transient fluid slosh model is analysed using the computational fluid dynamic method combined with the volume of fluid technique. The tank wagon dynamic model is solved using the fourth-order Runge–Kutta method based on the 19 degrees of freedom model with longitudinal, vertical, roll and pitch vibrations. The wheel–rail contact is considered according to nonlinear Hertzian and Kalker linear rolling contact theories. The fluid slosh model is validated using experimental data. The dynamic response characteristics of the partially filled railway tank wagon are investigated under straight-line braking manoeuvre using the coupled model. The results obtained from a parametric study, including the cross sectional shape and the filled volume show that the modified-oval cross section improves the dynamic response characteristics, which are attributed to its lower fluid's centre of gravity coordinate in the longitudinal direction and low lateral moment transfer of the fluid.
Fatigue-induced dual stiffness behavior of filled styrene–butadiene rubber
Authors: Liu Ruofan , Sancaktar Erol
Published: November 2018

Payne and Mullins effects are widely observed in reinforced rubber materials. The mechanisms by which these two effects work are not fully understood. Several models have been proposed, including molecular slippage model, bond rupture model, and filler rupture model. In this study, two different compounds of styrene–butadiene rubber were prepared using carbon black and silica as reinforcement fillers, respectively, and subjected to cyclic fatigue process. Tensile, creep, and relaxation tests were performed on fatigued samples to assess the residual stress–strain behavior by comparing with the results from similar tests using pristine (no fatigue) samples. When the tensile stiffness behavior of fatigued specimens was evaluated, we noted that the stiffness versus strain behavior which exhibited a monotonic decreasing–increasing behavior with the pristine specimens changed to what we call “dual-stiffness” condition, where the specimens went through a first (low) turning point as with the pristine samples, but then dropped off of a peak to go through a second softening stage, similar to the first softening stage of the pristine material. We believe that such spiking (dual) stiffness behavior characterized by a “Peak” point represents a combination of both Payne and the Mullins effects active during fatigue loading. We conclude that molecular slippage and bond rupture are the main factors affecting the physical properties of carbon black-filled compounds, while breakage and recombination of the filler are the key mechanisms affecting the silica-filled compounds during the fatigue process.
Where’s the roadmap? The transition from student to professional for new Master of Social Work graduates
Authors: Lynn Glassburn Susan
Published: November 2018

In 2015, more than 25,000 Master of Social Work (MSW) students in the U.S. graduated and embarked on their career, and while some studies have discussed this transition for undergraduates, few studies have focused solely on the school to work transition for MSWs. This grounded theory study focused on the professional journey of 27 new MSWs employed for less than 18 months. A conceptual five-stage model called Riding the Waves is proposed, which captures the transition experience. Implications for social work students, educators, and employers are discussed, including better preparing students for the transition, improving orientation and supervision, and providing the support that these new professionals require and deserve.
Influence of 3D warp interlock fabrics parameters made with flax rovings on their final mechanical behaviour
Authors: Corbin Anne-Clémence , Boussu François , Ferreira Manuela , Soulat Damien
Published: November 2018

The three-dimensional weaving process enables to produce near-net shaped complex preforms used as reinforcement of composite materials. However, the lack of knowledge on the mechanical behaviour of these three-dimensional woven structures may restrict their use for composite material. To fill this gap, we have tempted to highlight their specific mechanical properties according to their endogenous parameters. Based on these different architectures produced on the same weaving loom, several non-impregnated coupons have been mechanically characterized in all the directions of the three-dimensional warp interlock fabrics with quasi-static tensile tests in warp and weft directions as well as in-plane shear tests. According to our analyses, it has been revealed that the combination of several parameters as the woven pattern, the end and pick densities and the presence or not of stuffer warp yarns inside the three-dimensional fabrics may significantly influence the mechanical behaviour of the three-dimensional warp interlock architectures.
Thermal comfort properties of plasma-treated warp-knitted spacer fabric for the shoe insole
Authors: Rajan T Palani , Sundaresan S
Published: November 2018

Thermo-physiological comfort properties are crucial aspects of interlining material comfort for shoe insole which can be examined for permeability and conductivity. Air and water vapour permeability, conductivity and resistance of thermal are the main criteria for thermo-physiological comfort properties. Clothing comfort can be enhanced through special finishes including plasma which is one among the well known for surface modification. Oxygen and argon atmospheric plasma were used to analyse the comfort properties of polyester warp-knitted spacer fabric based on the fabric thickness and gas processing time. The outcomes exposed a notable influence in the comfort properties of polyester spacer fabrics after the atmospheric plasma processing time. The results too pointed out that the water vapour permeability and thermal resistance increased, although the air permeability and thermal conductivity decreased with the atmospheric plasma processing. When considering all the values of plasma-treated spacer fabrics, the 3 mm thickness of polyester spacer fabric proved to have better response and comfort properties than the 2 and 4 mm spacer fabrics. The findings show that final comfort properties of polyester warp-knitted spacer fabrics can be improved by using plasma treatments, and argon plasma treatment is the best method when compared to the oxygen plasma treatment.
An experimental study on the interdependence of mercerization, moisture absorption and mechanical properties of sustainable Phoenix sp. fibre-reinforced epoxy composites
Authors: Rajeshkumar G
Published: November 2018

This paper represents the first effort aimed to study the interdependence of mercerization, moisture absorption and mechanical properties of sustainable Phoenix sp. fibre-reinforced epoxy composites fabricated by compression moulding technique. The investigation was carried out by varying the fibre length (10, 20 and 30 mm), fibre volume fraction (10%, 20%, 30%, 40% and 50%), concentration of sodium hydroxide for fibre treatment (5%, 10% and 15%) and immersion temperature (10℃, 30℃ and 60℃). The fibre–matrix interface and failure mechanism was studied by using scanning electron microscopy. The results revealed that the moisture absorption rate increased with the increase in fibre length, fibre volume fraction and immersion temperature result in loss of tensile and flexural properties. The moisture absorbed samples shows 15% and 7% drop in tensile and flexural strength, respectively. However, this loss was less in mercerized fibre-reinforced composites.

Published: November 2018

The present work examined the thermo-mechanical characteristics of bio-fillers, namely Azadirachta indica seed powder, spent Camellia sinensis powder, their combinations filled jute fabrics–epoxy composites analytically and experimentally and compared it with the unfilled one. The test results showed that Azadirachta indica seed powder filled composites showed better mechanical properties with lesser voids, while spent Camellia sinensis powder and its composites showed better thermal stability. ANSYS analysis was used to show the stress distribution during the tensile and flexural testing. Scanning electron microscopy was used to study various characteristics of the fractured composites. A telephone stand was also fabricated to prove the application capability of best mechanical performer and analysed for deformation behaviour.
The Changing Landscape of Women’s Leadership in India and Korea From Cultural and Generational Perspectives
Authors: Chaudhuri Sanghamitra , Park Sunyoung , Kim Sehoon
Published: November 2018

This article attempts to (a) identify leadership challenges and opportunities among Korean and Indian women, and (b) explore how women’s leadership differs by generation in India and Korea. We provide suggestions for Indian and Korean women’s leadership research based on cultural and generational differences. Compared with Korean women leaders, Indian women leaders are more likely to take advantage of informal support and seek professional development opportunities. Although both Indian and Korean women leaders may have equal access to work–life balance programs and policies, they are not being fully utilized due to deep-rooted patriarchal traditions that still relegate women to the task of child rearing and stereotypical domestic roles. However, the probability of younger women leaders seeking informal support, professional development opportunities, and a work–life balance may be higher compared with their older generation coworkers in India and Korea. The findings and implications are discussed.

Published: November 2018

The technique of direct intratumoral injection of permanent liquid agents has evolved significantly over the past few decades. The percutaneous direct puncture technique is being utilised more and more for embolisation of head and neck hypervascular lesions. We describe a case treated via the direct percutaneous transnasal (TN) puncture technique for embolisation of a sinonasal hypervascular tumour, performed in a 21-year-old male patient. Due to extensive vascularisation of the tumour, preoperative embolisation was requested by our otolaryngologist team in order to minimise intraoperative bleeding and reduce surgical morbidity. A primary attempt at trans-arterial embolisation through selective ophthalmic artery catheterisation was unsuccessful due to unfavourable anatomy. An extensive devascularisation of the nasal fossa lesion was obtained using a single injection of low-density polymeric embolic agent (SQUID®). Post-operative eradication was uneventful. Final histopathology exam revealed vascular tumour consistent with a rare sinonasal glomangiopericytoma. To our knowledge, this is the first reported case of a rare sinonasal glomangiopericytoma treated by direct TN injection, utilising the liquid polymer agent SQUID®.

Published: November 2018

The transfemoral approach is a common technique for carotid artery stenting. However, it has the risk of distal embolism when stenting for a stenosis of the proximal common carotid artery because of poor stability of the guiding catheter resulting in difficulty in setting the embolic protection device prior to stenting. We present a novel therapeutic approach and technique for the treatment of tandem carotid stenoses including the proximal common carotid artery. A 63-year-old man presented with double stenoses at the common carotid artery and internal carotid artery. We used a transbrachial sheath guide that had a 6 Fr (2.24 mm, 0.088 inch) internal diameter and was 90 cm long, and was specifically designed for direct cannulation to the common carotid artery, like a modified Simmons catheter. Because the sheath guide positioned in the aortic arch made it possible to introduce safely the embolic protection device distal to the internal carotid artery stenosis without touching the plaque at the stenosis with no use of any coaxial catheters or guidewires, carotid artery stenting for tandem stenoses could be successfully carried out. The postoperative course was uneventful. In carotid artery stenting, especially for stenosis of the proximal common carotid artery, the sheath guide designed for transbrachial carotid cannulation was useful in stenting the tandem carotid stenoses.
Delayed intracranial aneurysm formation after cardiac myxoma resection: Report of two cases and review of the literature
Authors: Santillan Alejandro , Knopman Jared , Patsalides Athos , Pierre Gobin Y
Published: November 2018

Myxomas are slowly growing benign neoplasms and represent the most common tumor of the heart. Embolism from cardiac myxoma occurs in 30–45% of patients and in at least half of the cases cerebral arteries are affected leading mainly to embolic ischemic strokes and rarely to delayed intracranial aneurysm formation. We present two cases with delayed intracranial aneurysmal formation 14 years and 18 years after cardiac myxoma resection. To the best of our knowledge these two cases represent the longest time interval between aneurysm detection after complete cardiac myxoma resection with no recurrence confirmed by transesophageal echocardiogram. Our study also provides the longest clinical and radiological follow-up on this type of lesion.
Intravenous versus intra-arterial digital subtraction angiography: Occlusion rate and complication assessment of experimental aneurysms after flow diverter treatment in rabbits
Authors: Simgen Andreas , Tomori Toshiki , Bomberg Hagen , Yilmaz Umut , Roth Christian , Reith Wolfgang , Mühl-Bennighaus Ruben
Published: November 2018

Purpose

Conventional intra-arterial digital subtraction angiography, which requires surgical exposure and ligation of the femoral or carotid artery, is a limited method of evaluating elastase-induced aneurysms in New Zealand white rabbits. The purpose of this study was to assess aneurysm morphology, occlusion rates and complications after flow diverter treatment comparing intravenous and intra-arterial digital subtraction angiography.

Methods

We previously published a preclinical study in which we evaluated the occlusion rates of elastase-induced aneurysms after treatment with a prototype flow diverter, by using intra-arterial digital subtraction angiography at three months ( n = 9) and six months ( n = 9). In addition to that intravenous digital subtraction angiography before treatment, after one month (early follow-up group) and after three months (late follow-up group) was performed. Occlusion rates were compared within the two groups by means of residual contrast filling.

Results

Baseline aneurysm characteristics revealed no significant differences between intra-arterial digital subtraction angiography and intravenous digital subtraction angiography. Aneurysm occlusion rates in both follow-up groups using intravenous digital subtraction angiography were significantly higher compared to intra-arterial digital subtraction angiography (early follow-up group: intravenous digital subtraction angiography (one month) versus intra-arterial digital subtraction angiography (three months); p = 0.03 and late follow-up group: intravenous digital subtraction angiography (three months) versus intra-arterial digital subtraction angiography (six months); p = 0.04). Intravenous digital subtraction angiography is feasible to detect and reproduce device occlusions, in-stent stenosis and post-stent stenosis.

Conclusion

Intravenous digital subtraction angiography can not give a sufficient statement on the aneurysm occlusion process compared to intra-arterial digital subtraction angiography and is therefore not recommended for imaging follow-up after flow diverter treatment in rabbits. Regarding untreated aneurysms and complications like device occlusions, in-stent stenosis and post-stent stenosis intravenous digital subtraction angiography proofed to be a good alternative to intra-arterial digital subtraction angiography in our study.
Acute administration of tirofiban versus aspirin in emergent carotid artery stenting
Authors: Gruber Philipp , Hlavica Martin , Berberat Jatta , Victor Ineichen Benjamin , Diepers Michael , Nedeltchev Krassen , Kahles Timo , Remonda Luca
Published: November 2018

Background

Carotid artery stenting requires antiplatelet therapy for prevention of in-stent thrombosis. Patients suffering from acute ischemic stroke undergoing intravenous thrombolysis and emergent carotid artery stenting (eCAS) are at high risk for intracranial bleeding. We assessed efficacy and safety of acute administration of intravenous tirofiban versus aspirin in these patients.

Methods

A retrospective, single center, cohort study was carried out of 32 patients who underwent eCAS (18 received tirofiban, 14 received aspirin) at our comprehensive stroke center (2008–2016).

Results

Of our 32 consecutive eCAS patients, favorable clinical outcomes (modified Rankin scale ≤ 2) were achieved in eight (47%) tirofiban patients and six (46%) aspirin patients ( p = 0.96). Overall rates were similar for symptomatic intracranial bleeding (tirofiban 22%, aspirin 29%, p = 0.68) and mortality (tirofiban 18%, aspirin 23%, p = 0.71).

Conclusions

Tirofiban and aspirin demonstrated similar efficacy and safety in thrombolyzed stroke patients who underwent eCAS in our cohort. Intravenous tirofiban with its short half-life might represent an alternative to aspirin in select patients.
Persistent hypoglossal artery aneurysm: Case report and qualitative systematic review
Authors: Tse George H , Martin Andrew , Dyde Richard A , Coley Stuart C
Published: November 2018

A persistent hypoglossal artery was first described in 1889 and is one of the more common anatomical variations arising from aberration in normal development. Endovascular coiling has been recognised as a robust treatment for acutely ruptured intracranial arterial aneurysms, although specific data regarding an aneurysm arising from a persistent hypoglossal artery is lacking due to the low incidence. Here we report both the oldest patient reported to be treated with a persistent hypoglossal artery-associated aneurysm and also explicitly report endovascular treatment of a persistent hypoglossal artery aneurysm arising at the posterior inferior cerebellar artery origin. Qualitative systematic review of the available medical literature demonstrates limited evidence regarding treatment of persistent hypoglossal artery-associated aneurysms with the majority being carried out via open surgery. Ruptured posterior inferior cerebellar artery aneurysm arising from a persistent hypoglossal artery can be successfully and safely treated by endovascular therapy via the persistent hypoglossal artery. Randomised study of this situation is unlikely to be feasible; however, qualitative review of the literature reveals six such aneurysms that have been treated surgically, and this case appears to be the first via an endovascular means.

Authors: Bohara Manoj , Teranishi Kosuke , Yatomi Kenji , Fujii Takashi , Kitamura Takayuki , Yamamoto Munetaka , Oishi Hidenori
Published: November 2018

Background

Flow diversion with the Pipeline embolization device (PED) is a widely accepted treatment modality for aneurysm occlusion. Previous reports have shown no recanalization of aneurysms on long-term follow-up once total occlusion has been achieved.

Case description

We report on a 63-year-old male who had a large internal carotid artery cavernous segment aneurysm. Treatment with PED resulted in complete occlusion of the aneurysm. However, follow-up angiography at four years revealed recurrence of the aneurysm due to disconnection of the two PEDs placed in telescoping fashion.

Conclusion

Herein, we present the clinico-radiological features and discuss the possible mechanisms resulting in the recanalization of aneurysms treated with flow diversion.
Surgical options in experimental porcine model for endovascular training in complex vascular lesions

Published: November 2018

We describe a new, elegant, two-phase, microsurgical method that minimizes the surgical preparation time for different complex vascular lesions in a swine model. In the first phase, the model is prepared microsurgically in the experimental laboratory using arterial or/and venous grafts. In the second phase, the model is implanted in the experimental animal. This two-fold method allows for increasing the complexity and accuracy of the model while reducing preparation time on the day of the training session.
‘Now it's indie’: The creative turn of the cultural policy in the Korean indie music scene
Authors: Kim Soochul
Published: November 2018

As creative industry policy discourse has travelled quickly across the South Korean cultural industry, including the Korean Wave and beyond, the indie music artists in South Korea have found opportunities to perform and promote their music overseas. The recent cultural policy along with the direct support programs are unexpected, because of the conservative nature of the government and the nature of the South Korean indie music as independent from political and economic powers. With the example of the overseas advance of South Korean indie artists, with government support, this article presents an examination of the complex relationship between the government's creative cultural policy and the resulting effects of the policies on the South Korean indie music scene. It is argued that it is yet to be determined whether the cultural policy is having a negative or positive effect on the cultural industry. This article suggests that the cultural policy, whatever the goals of the policy-makers, is interacting with other elements—such as the political economy of the technologies of distribution and consumption, subculture, and the methods through which the cultural policy discourse is articulated among the policy community—beyond the objectives of the policy itself.
Comparing legacy media responses to the changing business of news: Cross-national similarities and differences across media types
Authors: Cornia Alessio , Sehl Annika , Kleis Nielsen Rasmus
Published: November 2018

In this article, we analyse how legacy media organizations in six countries are adapting to the changing business of news. We focus on how similarities and differences in their responses to digital developments are shaped by the interplay between organizational legacy and national context. The study draws on media sociology and comparative media systems research and is based on 54 interviews with senior editors and managers at 25 newspapers and commercial broadcasters in Finland, France, Germany, Italy, Poland, and the UK. We find that organizations within the same medium respond to change in similar ways (newspapers versus broadcasters), and that these responses are surprisingly similar across different countries. We argue that factors related to the medium-specific legacy shape media adaptation more than do structural differences between national media systems because news organizations faced with a changing and uncertain environment imitate the strategies adopted by peer organizations elsewhere.

Published: November 2018

Sleep disturbance is a frequent symptom of carpal tunnel syndrome. The aim of this study was to investigate the effect of median nerve decompression on sleep quality of patients with this condition. The study sample consisted of 41 patients with severe carpal tunnel syndrome who were admitted to our clinic and treated with open median nerve decompression. Sensation and functional recovery of the patients were followed using the Boston Function Questionnaire, the Semmes–Weinstein monofilament test and the two-point discrimination test. Symptomatic recovery of the patients was followed by the Boston Symptom Questionnaire. The tests were used before surgery and at three and six months afterwards. Sensory, functional and symptomatic recovery from the third month to the sixth month following surgery also affected sleep parameters and improved the sleep quality of patients with carpal tunnel syndrome.

High aldosterone, hypertension and adrenal adenoma in a 36-year-old pregnant patient: Is this primary aldosteronism?
Authors: Berberich Amanda J , Penava Deborah , Sun Dongmei , MacDougall Arlene , Lum Andrea , Van Uum Stan
Published: November 2018

A 36-year-old woman presented at 16 weeks’ gestation with severe hypertension. In comparison to the non-pregnant reference normal ranges, potassium was 3.1-3.9 mmol/L, aldosterone 2570-3000 pmol/L (N 250-2885) renin was unsuppressed (24-76.4 ng/L (N1.7–23.9)), with aldosterone to renin ratios in the reference range. An adrenal MRI scan demonstrated a 1.8 × 1.4 cm left adrenal adenoma. Primary aldosteronism was strongly suspected and surgery considered. However, she was managed conservatively with labetalol and modified-release nifedipine with no obstetric complications. Post-partum blood pressures remained elevated with normal aldosterone (539 pmol/L), unsuppressed renin (5.2 ng/L) and normal aldosterone-to-renin ratio (104 (N < 144)). Suspected primary hyperaldosteronism is challenging to investigate and manage in pregnancy. The accepted screening and confirmatory tests are either contraindicated or not validated in pregnancy. Pregnancy has significant effects on the renin-angiotensin-aldosterone pathway leading to physiologic elevations in both aldosterone and renin. While primary hyperaldosteronism has been associated with poor pregnancy outcomes, optimal management in pregnancy is not clearly established.
The biochemical diagnosis of intrahepatic cholestasis of pregnancy
Authors: Morton Adam , Laurie Josephine
Published: November 2018

Background

Bile acid levels and liver function tests may be normal at presentation in women with intrahepatic cholestasis of pregnancy. The biochemical results of patients presenting with pruritus typical for intrahepatic cholestasis of pregnancy were reviewed.

Methods

A retrospective audit of women coded as having intrahepatic cholestasis of pregnancy over a three-year period.

Results

One hundred and ninety-three women (1.1% of the obstetric population) presented with pruritus typical of intrahepatic cholestasis of pregnancy. Forty (21%) of these women had normal biochemistry at presentation, half subsequently developing abnormal results. Women with a history of allergic reactions were more likely to develop intrahepatic cholestasis of pregnancy.

Conclusions

Normal biochemistry should not preclude a trial of ursodeoxycholic acid in women with distressing pruritus typical for intrahepatic cholestasis of pregnancy. Biochemical tests which are more sensitive and specific in the diagnosis of intrahepatic cholestasis of pregnancy would be valuable. Investigation of other populations with intrahepatic cholestasis of pregnancy regarding a possible association with atopy/allergy would be interesting.

Published: November 2018

Background

Although optimal bowel preparation is essential for high‐quality screening colonoscopy, documentation of preparation quality, patient satisfaction and adherence is scarce.

Aim

The aim of this article is to compare low‐volume (LV, 300 ml sodium picosulfate), intermediate‐volume (IV, 2 l polyethylene glycol, PEG + ascorbic acid and sodium ascorbate), and high‐volume (HV, 4 l PEG) purgatives.

Results

A total of 5000 individuals (50.5% women) were enrolled between March 2015 and July 2017 (LV:IV:HV = 3.61:1.54:1). Overall sex‐ and age‐adjusted adenoma detection rate was 25.4% (LV 23.8%, IV 25.4%, HV 29.8%), median age was 59.6 years, and cleansing was successful in 96.8%. Success rates of bowel cleansing were highest with HV (97.6%), followed by LV (97.2%) and IV (95.3%) with OR 2.04 (CI 95% 1.20–3.45, p = 0.008) and OR 1.79 (CI 95% 1.27–2.50, p = 0.001), respectively, compared to IV. A total of 93.5% of the LV group would use the same purgative in the future, 73.2% of IV and 69.4% of HV. A total of 84.4% would prefer overnight preparation, 12.1% same‐day preparation.

Conclusion

All purgatives investigated showed good bowel cleansing quality results, patient satisfaction and compliance. Improvement in patient information might lead to even higher participation rates in screening colonoscopy since one in five patients stated that bowel preparation worried him or her most prior to colonoscopy.

The European Society of Gastrointestinal Endoscopy (ESGE) and United European Gastroenterology present a list of key performance measures for endoscopy services. We recommend that these performance measures be adopted by all endoscopy services across Europe. The measures include those related to the leadership, organization, and delivery of the service, as well as those associated with the patient journey. Each measure includes a recommendation for a minimum and target standard for endoscopy services to achieve. We recommend that all stakeholders in endoscopy take note of these ESGE endoscopy services performance measures to accelerate their adoption and implementation. Stakeholders include patients and their advocacy groups; service leaders; staff, including endoscopists; professional societies; payers; and regulators.

Authors: Richardson A , Haridass SA , Ward E , Ayres J , Baskind NE
Published: November 2018

Objectives

To assess compliance with the European Society for Human Reproduction and Embryology (ESHRE) guidelines on the investigation and management of women with premature ovarian insufficiency at the Leeds Teaching Hospitals NHS Trust (LTHT) and to determine whether this varies depending on the clinical setting in which the women present.

Study design

A retrospective review of all females diagnosed with premature ovarian insufficiency between 1 July 2016 and 30 June 2017, presenting to one of the following clinics: reproductive medicine, specialist menopause, general gynaecology, oncology long-term follow-up, general endocrinology or paediatric endocrinology.

Main outcome measures

Proportion of patients who had the necessary investigations performed and relevant treatment options discussed.

Results

103 women were included in the study. Overall, 40.6% had a karyotype. Screening for the Fragile-X pre-mutation, thyroid peroxidase and 21-hydroxylase antibodies occurred in 7.4%, 11.1% and 13.6% of women, respectively. Only 35.9% had their bone mineral density measured. There was significant variation in the performance of a karyotype (p < 0.001) and thyroid peroxidase antibodies (p < 0.01) between the different clinical settings. Overall, lifestyle advice was offered to 30.1%. Estrogen replacement, contraception, fertility options and bone protection were discussed with 76.0%, 38.4%, 59.0% and 75.0%, respectively. Psychological support was offered to 25.2%. There was significant variation for all apart from contraception.

Conclusion

The investigation and treatment of women with premature ovarian insufficiency at the LTHT is not consistent with the ESHRE guidelines and requires improvement. Furthermore, there is significant variation in management depending on the department to which the patient initially presents.

Acute myeloid leukemia (AML) is an age-related disease that is highly dependent on the bone marrow (BM) microenvironment. With increasing age, tissues accumulate senescent cells, characterized by an irreversible arrest of cell proliferation and the secretion of a set of proinflammatory cytokines, chemokines, and growth factors, collectively known as the senescence-associated secretory phenotype (SASP). Here, we report that AML blasts induce a senescent phenotype in the stromal cells within the BM microenvironment and that the BM stromal cell senescence is driven by p16INK4a expression. The p16INK4a-expressing senescent stromal cells then feed back to promote AML blast survival and proliferation via the SASP. Importantly, selective elimination of p16INK4a+ senescent BM stromal cells in vivo improved the survival of mice with leukemia. Next, we find that the leukemia-driven senescent tumor microenvironment is caused by AML-induced NOX2-derived superoxide. Finally, using the p16-3MR mouse model, we show that by targeting NOX2 we reduced BM stromal cell senescence and consequently reduced AML proliferation. Together, these data identify leukemia-generated NOX2-derived superoxide as a driver of protumoral p16INK4a-dependent senescence in BM stromal cells. Our findings reveal the importance of a senescent microenvironment for the pathophysiology of leukemia. These data now open the door to investigate drugs that specifically target the “benign” senescent cells that surround and support AML.
Improving the personalisation of care in a district nursing team: a service improvement project
Authors: McKendry Mandy , Green Helen
Published: November 2018

Service users can benefit in a variety of ways from a personalised approach to care. This service improvement project aimed to improve personalisation for patients being cared for by a community nursing team in the south of England. A plan, study, do, act (PDSA) approach to the project was undertaken with a community nursing team. Both quantitative and qualitative data showed improvement once the focus on personalisation had been improved. Patient and staff satisfaction scores improved and a documentation audit showed the focus on personalisation had increased. Qualitative data suggested that personalisation had also saved staff time, although this measurement was not included in the project. A focus on personalisation can be beneficial for staff and service users

Objective:

Wound assessment is an essential part of wound management and has traditionally focused on the wound bed. The Triangle of Wound Assessment (Triangle) is a new assessment tool that includes a holistic evaluation of the patient with a wound. The aim of this pilot study was to describe the use of the Triangle in our clinical practice in Spain.

Methods:

Prospective, consecutive patients, male and female, over 18 years old, with wounds of any aetiology and duration, who attended the centres involved in the study, were recruited between May and June 2017. The TWA was used during the first presentation, to assess the wound bed, edge and periwound skin. The study's expert panel met to discuss the results collected by the assessment, as well as the advantages and disadvantages of the system.

Results:

We recruited 90 patients. Non-viable tissue (necrotic/sloughy) was recorded in 57.8% of the patients, elevated exudate (medium/high) in 52.2%. Approximately 25% of the patients had signs or symptoms of local infection. Maceration was the most prevalent issue recorded on the wound edge and periwound skin assessment, affecting 31.1% and 30.0% of the patients, respectively. The presence of hyperkeratosis was high for the study population as the main aeitologies of the wounds identified here were DFU.

Conclusions:

The implementation of Triangle Wound Assessment could help in the holistic approach to patient care by focusing on more than local wound care, identifying barriers to achieving wound healing and evaluating wound response and patient compliance.
LA PRODUCCIÓN METÁLICA DE ÉPOCA ROMANA EN MINA DE SÃO DOMINGOS (MÉRTOLA, PORTUGAL)
Authors: Pérez Macías Juan Aurelio , Rego Miguel
Published: November 2018

Com este trabalho fazemos um périplo pela história contemporânea da exploração mineira em São Domingos (Mértola, Portugal), quando foram postos a descoberto a maioria dos trabalhos mineiros romanos e dos seus equipamentos de mineração. Todos estes achados arqueológicos confirmam que esta mina terá sido um dos principais coutos mineiros do sudoeste peninsular no período romano. Embora a maior parte dos vestígios a ela associados tenham sido destruídos pela actividade recente da mina, restam, no entanto, os grandes escoriais romanos que comprovam a produção de metais nesta mina. O nosso trabalho teve como objectivo definir a que tipo de metalurgia corresponde cada um daqueles escoriais. Os resultados das nossas análises confirmam que em época romana esta mina produziu prata e cobre, tendo ocorrido o seu período de maior actividade durante a primeira metade do séc. I d.C. Palavras
