Authors: Litrenta Jody M. , Mu Brian H. , Chen Austin W. , Perets Itay , Ortiz-Declet Victor , Domb Benjamin G. 
Published: February 2019

Background: The success of hip arthroscopy has led to increased application in younger populations. However, hip arthroscopy remains a challenging procedure, and its safety and efficacy in the adolescent population have been controversial. Most existing literature on outcomes in such patients contains only short-term follow-up, and a paucity of evidence is available regarding long-term outcomes in adolescents. Purpose: To report on clinical outcomes at a minimum 5-year follow-up in patients younger than 18 years who underwent arthroscopic treatment of labral tears. Study Design: Case series; Level of evidence, 4. Methods: Data were prospectively collected and retrospectively reviewed on all patients younger than 18 years who underwent hip arthroscopy in a tertiary hip preservation setting at a single institution. Patients were excluded if they had previous ipsilateral hip conditions or surgery. All patients underwent either labral repair or debridement for treatment of a labral tear. Patient-reported outcome measures were recorded at 3 months and at 1, 2, or a minimum of 5 years. These included the modified Harris Hip Score (mHHS), Nonarthritic Hip Score, Hip Outcome Score–Sports Specific Subscale (HOS-SSS), visual analog scale, and patient satisfaction. Additionally, the abbreviated International Hip Outcome Tool and Short Form Health Survey were collected at latest follow-up. Results: The study included 44 hips in 32 patients that underwent arthroscopic labral repair (86.4%) or labral debridement (13.6%) between April 2008 and April 2011, with latest follow-up at a mean of 69.2 months (range, 60.0-89.9 months) postoperatively. The average age at surgery was 16.3 years (range, 14.2-17.9 years), and 39 hips from female patients. Statistically significant improvements were seen in all patient-reported outcome measures from preoperative to minimum 5-year follow-up. Improvements were noted at 1-year follow-up and maintained at minimum 5-year follow-up. At the latest follow-up, the Patient Acceptable Symptomatic State was achieved in 95.5% of patients for the mHHS and 72.7% for the HOS-SSS. Two patients subsequently underwent secondary arthroscopy on the ipsilateral hip; however, the survivorship of all hips was 100%. Conclusion: Hip arthroscopy for the treatment of labral tears in adolescents remains a technically challenging procedure that should be approached with appropriate caution. The results of the present study on a population treated in a specialized hip preservation center demonstrate that hip arthroscopy is a safe procedure with stable improvement in patient-reported outcome measures at 5 years.
(Re)making labour markets and economic crises: The case of Ireland
Authors: Murphy Enda , Mercille Julien 
Published: February 2019

The 2008 economic crisis has had significant impacts on labour markets around the world. In Europe, in particular, the need for internal devaluation within European Union nations in financial difficulty precipitated a wave of labour market reforms alongside the reform of welfare systems struggling to cope with high levels of unemployment. Various analyses have explored the nature of these changes separately for the labour market and welfare systems. Using a conceptual framework rooted in a political economy understanding the social nature of labour, this article takes an inclusive approach to understanding regulatory changes for both employed and unemployed labour. We do this using the case of Ireland, a country that went through a severe economic crisis, was subject to a European Union/European Central Bank/International Monetary Fund bailout in 2010 and witnessed one of the most significant labour market crises in Europe. The Irish case is instructive because it highlights both the range and depth of regulatory interventions utilised by the state during periods of crisis to deal with the social nature of labour and its role under advanced capitalism.

Published: February 2019

Background Multiple factors have been reported to affect adherence to medication, including beliefs about medicines, while specifically tailored pharmaceutical care services for patients may improve adherence. The aim was to assess the impact of counselling by an oncology pharmacist on patients' medication adherence and beliefs. Methods An interventional prospective study was performed in the oncology department at a tertiary hospital in Northern Cyprus from November 2017 to April 2018. The Beliefs about Medicines Questionnaire was used to evaluate the balance between beliefs about necessity and concerns and medication beliefs before and after an educational intervention. The Morisky Green Levine Test 2018 was used to evaluate adherence. Results In total, 81 patients (65.4% females; mean age: 59.1 ± 11.34 years; 34.6% hypertensive; 19.8% with diabetes) were analysed before and after receiving counselling from an oncology pharmacist. Pharmacist education significantly enhanced the mean patient necessity-concern balance scores by two-fold (MT0(baseline) = −3.1 ± 8.6; MT1(posteducation) =3.0 ± 7.3; p < 0.0001), with patients who received counselling for the first time experiencing the greatest benefit. Multivariate analysis showed that patients who had a negative balance between their beliefs about the necessity of the medication and their concerns were less likely to adhere to the medication (0.138 (0.025–0.772)). Conclusion Counselling by an oncology pharmacist was effective in decreasing patient concerns and increasing their understanding of the necessity of the medication, thus enhancing their adherence and consequently improving the care they received.
The effects of N-acetylcysteine on radiotherapy-induced small intestinal damage in rats

Published: February 2019

Six million cancer patients worldwide receive radiotherapy, either alone or in combination with other cancer treatments annually. The purpose of this study was to investigate, at the structural and molecular levels, the protective effect of N-acetylcysteine (NAC), a powerful antioxidant, against radiotherapy-induced damage on the intestinal system. Three study groups were constituted: control (group 1: no radiotherapy), radiotherapy (RT; group 2), and RT + NAC (group 3). The NAC group received 300 mg/kg NAC orally for five days before irradiation. At the end of the 5th day, 6 Gy was irradiated once, and 300 mg/kg NAC was administered orally for two days following irradiation. NAC drug administration was maintained for a total of seven days. At the end of the study, the rats were euthanized by the administration of anesthetic agents and sacrificed. The malondialdehyde (MDA) levels and caspase-3 expression increased and glutathione (GSH) levels decreased in RT rats compared to the control group ( p < 0.05). NAC reduced MDA levels, and caspase-3 expression, and increased GSH levels in the small intestine caused by RT ( p < 0.05). Therefore, NAC may be useful in the prevention of gastrointestinal syndrome in patients undergoing radiotherapy in the treatment of malignancy. Impact statement Some six million cancer patients currently receive radiotherapy. Radiotherapy eliminates cancer cells by accelerating their death. However, radiotherapy is not selective, and it therefore harms healthy tissues around cancerous tissue. The latest studies have shown that the irradiation of biological materials causes a rapid increase in reactive oxygen species (ROS) in the tissue as a result of exposure of the target molecule to direct and indirect ionization. N-acetylcysteine (NAC) is an antioxidant that permits the elimination of free oxygen radicals and that contributes to glutathione synthesis. Our study, therefore, examined the effects of radiation resulting from radiotherapy on the small intestine at the molecular level, and prospectively considered the potential protective characteristics of NAC against gastrointestinal syndrome resulting from radiotherapy.
Corrective osteotomy for a malunited proximal radius fracture causing radio-capitellar dislocation in a paediatric patient: A case report
Authors: Haines Samuel , Amirfeyz Rouin 
Published: February 2019

Background Malunited proximal radius fractures causing dislocation of the radio-capitellar joint are rare. We present a case of a two-year-old female patient with such an injury who was treated with a proximal radius osteotomy with good long-term outcomes. Method/results Case study of a single patient with a malunited proximal radius fracture which was identified as causing radio-capitellar dislocation who underwent corrective osteotomy with a good result. Conclusion Our opinion is that a corrective osteotomy for a malunited proximal radius fracture causing radio-capitellar dislocation is a sound treatment option and that no supplementary soft tissue reconstruction such as annular ligament exploration/reconstruction is necessary.
Experimental testing of semirigid corrugated baffles for the suppression of tube waves in vertical seismic profile data
Authors: Greenwood Andrew , Christian Dupuis J. , Kepic Anton , Urosevic Milovan 
Published: February 2019

Multichannel borehole hydrophone strings are a low-cost, low-risk, alternative to borehole clamping geophones. Vertical seismic profile (VSP) data collected with hydrophones, however, suffer from high-amplitude coherent tube-wave noise. This reduces the usable data to the first arrivals and traveltimes for check-shot surveys. To significantly reduce tube-wave noise from VSP data acquired with hydrophones, we have designed and tested a novel tube-wave attenuation baffle. The effectiveness of the baffle was first verified in a laboratory-scale experiment and then in a borehole drilled into a hardrock environment. The laboratory experiments tested the performance of four different baffle topologies, whereby the best performing topology was the semirigid corrugated pipe baffle. This design reduced the amplitude of the tube wave with more than 40 dB and was logistically easy to deploy. The field experiment investigated the effectiveness of three different semirigid corrugated pipe baffle topologies in a PQ (123 mm) diamond drillhole in Western Australia. Here, we found that the semirigid corrugated pipe baffle was effective in disrupting tube-wave propagation. The 100 mm diameter baffle achieved an impressive 60 dB of tube-wave attenuation, whereas the 50 mm baffle had a modest attenuation of 10–15 dB. This suggests that the performance of this new type of baffle is best when the diameter of the baffle is closely matched to the diameter of the borehole. The results of these experiments have signiﬁcant implications because hydrophone arrays with a large number of receivers are comparatively inexpensive and simpler to deploy than borehole geophone counterparts. The development of hydrophone arrays that are free of interfering borehole modes could allow VSPs to be acquired in situations in which seismic-polarity information is not required and could help VSP gain traction in cases in which the cost of acquisition has precluded its use until now.
Can Health Insurance Regulations Generate Citizen Constituencies?
Authors: Chattopadhyay Jacqueline 
Published: February 2019

Abstract
Context: A political science literature has emerged on the policy feedback effects of alternative health care coverage expansions, focusing on whether programs like Medicare, Medicaid, and the Affordable Care Act can generate robust public constituencies. Yet, scholars have mainly examined direct governmental benefits and rarely studied the feedback effects from the underlying regulatory frameworks that allow health care markets to function, such as regulations that determine eligibility for nongroup and continuation coverage.
Methods: Drawing on literature from multiple disciplines, this article analyzes political and policy factors that promote and undermine such regulations' capacity to stimulate positive feedback and the emergence of citizen constituencies.
Findings: While some factors may help these regulations to cultivate constituencies, there are barriers to this positive feedback generation. The most notable is the failure of these regulatory policies to confer politically useful resources on citizens unless other, mutually supportive policies are also in place, such as policies to control premiums.
Conclusions: Steps in the policy feedback model that are typically left unexplored in the literature deserve greater scrutiny when scholars examine the weak self-reinforcing effects of health insurance regulations. A take-away lesson, relevant to the Affordable Care Act, is that even when policies broaden nongroup coverage and ostensibly assist many people, a robust citizen constituency is unlikely to emerge, leaving key protections of access to health insurance vulnerable to erosion or reversal over time.
Political Participation in the Least Healthy Place in America: Examining the Political Determinants of Health in the Mississippi Delta
Authors: Jones David K. 
Published: February 2019

AbstractContext: Scholars have called on public health to more commonly and more effectively learn from political science to understand the political determinants of health. They argue that policy decisions affecting health cannot be understood without appreciating the political dynamics shaping key institutions. As the least healthy place in the United States, the Mississippi Delta provides valuable insights on the connections between power, political participation, and health.Methods: This case study relies on historical analysis, a review of the literature, and descriptive analysis of a unique data set examining every law introduced in the Mississippi legislature during the 2017 legislative session.Findings: Legislators from the Delta have comparatively little influence in state-level policy making in Mississippi. This lack of power has deep historical roots but persists today.Conclusions: This examination of power in the Mississippi Delta raises questions about the ability of the political process to achieve health equity. Systemic barriers to power, including structural racism, suggest that policies that would advance health equity cannot happen without the support of white residents, particularly those living in other parts of the state. In other words, health equity is not likely to be achieved without buy-in from leaders outside the area with the greatest need.

ABSTRACT

Purpose
We hypothesized that respiratory muscle endurance training (RMET) in hypoxia induces greater improvements in respiratory muscle endurance with attenuated respiratory muscle metaboreflex and consequent whole-body performance. We evaluated respiratory muscle endurance and cardiovascular response during hyperpnoea and whole-body running performance before and after RMET in normoxia and hypoxia.

Methods
Twenty-one collegiate endurance runners were assigned to control (n = 7), normoxic (n = 7), and hypoxic (n = 7) groups. Before and after the 6 wk of RMET, incremental respiratory endurance test and constant exercise tests were performed. The constant exercise test was performed on a treadmill at 95% of the individual’s peak oxygen uptake (V˙O2peak). The RMET was isocapnic hyperpnoea under normoxic and hypoxic conditions (30 min·d−1). The initial target of minute ventilation during RMET was set to 50% of the individual maximal voluntary ventilation, and the target increased progressively during the 6 wk. Target arterial oxygen saturation in the hypoxic group was set to 90% in the first 2 wk, and thereafter it was set to 80%.

Results
Respiratory muscle endurance was increased after RMET in the normoxic and hypoxic groups. The time to exhaustion at 95% V˙O2peak exercise also increased after RMET in the normoxic (10.2 ± 2.4 to 11.2 ± 2.6 min) and hypoxic (11.5 ± 2.6 to 12.6 ± 3.0 min) groups, but not in the control group (9.6 ± 3.2 to 9.4 ± 4.0 min). The magnitude of these changes did not differ between the normoxic and the hypoxic groups (P = 0.84).

Conclusion
These results suggest that the improvement of respiratory muscle endurance and blunted respiratory muscle metaboreflex could, in part, contribute to improved endurance performance in endurance-trained athletes. However, it is also suggested that there are no additional effects when the RMET is performed in hypoxia.
Transit Pattern Detection Using Tensor Factorization
Authors: Du Bowen , Zhou Wenjun , Liu Chuanren , Cui Yifeng , Xiong Hui 
Published: February 2019

Understanding citywide transit patterns is important for transportation management, including city planning and route optimization. The wide deployment of automated fare collection (AFC) systems in public transit vehicles has enabled us to collect massive amounts of transit records, which capture passengers’ traveling activities. Based on such transit records, origin–destination associations have been studied extensively in the literature. However, the identification of transit patterns that establish the origin–transfer–destination (OTD) associations, in spite of its importance, is underdeveloped. In this paper, we propose a framework based on transit tensor factorization (TTF) to identify citywide travel patterns. In particular, we create a transit tensor, which summarizes the citywide OTD information of all passenger trips captured in the AFC records. The TTF framework imposes spatial regularization in the formulation to group nearby stations into meaningful regions and uses multitask learning to identify traffic flows among these regions at different times of the day and days of the week. Evaluated with large-scale, real-world data, our results show that the proposed TTF framework can effectively identify meaningful citywide transit patterns.

Angola's whites: political behaviour and national identity
Authors: Pimenta Fernando Tavares 
Published: February 2019

Abstract
This is a study of the political behaviour and of the national identity of the white settler community in Angola. Analysis of the political behaviour of Angola's white settlers, the second-largest settler community in Africa in 1970, indicates that they not only developed a form of local economic nationalism, but that they actually created a kind of African identity that added a more political aspect to this nationalism. Settlers organized themselves into political movements and parties that called for Angola's political autonomy and even its independence. However, settler nationalism was repressed by the Portuguese government and rejected by the black nationalist movements. White settlers were unable to impose their political views, and as a result of Angola's violent independence process, a large proportion of them left the country in 1975.

Umbilical Cord Tissue Derived Mesenchymal Stem Cells Can Differentiate into Skin Cells

Published: February 2019

AbstractAutologous skin grafts are used to treat severe burn wounds, however, the availability of adequate donor sites makes this option less practical. Recently, stem cells have been used successfully in tissue engineering and in regenerative medicine. The current study aims to differentiate umbilical cord tissue derived mesenchymal stem cells (CT-MSCs) into skin cells (fibroblasts and keratinocytes) for use to treat severe burn wounds. After isolation, MSCs were characterized and their growth characteristics were determined. The cells were induced to differentiate into fibroblasts and keratinocytes using respective induction medium. Results indicated that CT-MSCs were spindle shaped, plastic adherent and positive for CD29, CD44, CD73, CD90 markers. CT-MSCs also showed high proliferative potential as indicated by cumulative population doubling, doubling time and plating efficiency. The MSCs were successfully differentiated into fibroblast and keratinocytes as indicated by morphological changes and expression of lineage specific genes. We propose that these differentiated skin cells which are derived from CT-MSCs can thus be used for the development of bioengineered skin; however, further studies are required to evaluate the utility of these substitutes.
