Authors: Hildebrand Alexandra H , Zhang Betty , Horner Nolan S , King Graham , Khan Moin , Alolabi Bashar 
Published: July 2019

Background Radial head excision has historically been a common surgical procedure for the operative management of radial head fractures and post-traumatic conditions. With recent advances in other surgical techniques, controversy exists regarding its indications. This review evaluates the indications and outcomes of radial head excision in traumatic and non-traumatic elbow pathology. Methods Multiple databases were searched for studies involving radial head excision. Screening and data abstraction were conducted in duplicate. Only studies reporting outcomes for radial head excision were included. Results Twenty-seven studies with 774 radial head excision patients were included. The most common indications involved acute excision of comminuted radial head fractures (n = 347) and rheumatoid arthritis (n = 201). Post-operative functional scores after acute excision were reported to be good to excellent. In the chronic setting of rheumatoid disease, radial head excision resulted in improved range of motion, although pain was not effectively relieved. Discussion Outcomes of radial head excision for acute fracture are good to excellent; however, it should not be performed when concurrent or ligamentous injuries are present. Although some studies compared excision to open reduction and internal fixation or replacement, more data are needed to make proper conclusions. The strength of these conclusions is limited by the quality of included literature.

Aims The aim of this study was to evaluate the associations of blood pressure categorization based on the 2017 American College of Cardiology and American Heart Association guideline with the risk of peripheral artery disease (PAD). Methods Among 13,113 middle-aged participants, we investigated the associations of 2017 blood pressure categories (systolic <120 and diastolic <80 mmHg (normal if no anti-hypertensive medications; reference), 120–129 and <80 (elevated), 130–139 and/or 80–89 (stage 1 hypertension), and ≥140 and/or ≥90 (stage 2 hypertension)) with incident PAD (hospitalizations with a diagnosis or leg revascularization) using Cox regression models. Analyses were separately conducted in individuals with and without anti-hypertensive medications. Results During a median follow-up of 25.4 years, 466 incident PAD occurred (271 cases in 9858 participants without anti-hypertensive medications). In participants without anti-hypertensive medications, we observed significant hazard ratios of PAD in elevated blood pressure (1.80 (1.28–2.51)) and stage 2 hypertension (2.40 (1.72–3.34)), but not in stage 1 hypertension. Analyzing systolic and diastolic blood pressure separately, higher systolic blood pressure categories showed significant associations with incident PAD in a graded fashion whereas, for diastolic blood pressure, only ≥90 mmHg did. Generally similar patterns were seen among participants on anti-hypertensive medication, while they had higher risk of PAD than those without at each blood pressure category. Conclusions Systolic blood pressure, including the category of 130–139 mmHg, showed stronger associations with incident PAD than did diastolic blood pressure. Consequently, elevated blood pressure conferred similar or even greater risk of PAD than stage 1 hypertension, with implications on how to interpret new blood pressure categories in terms of leg vascular health.
The Principle of Protecting the Best Interests of the Child in Shia Jurisprudence and Iran’s Legal System with Emphasis on Custody (New Understanding of a Traditional Legal Concept)

Published: July 2019

In this article, children’s rights will be studied in the Iranian legal system with remarks on its references in the Shia Jurisprudence. One of the main issues regarding children, is their guardianship, custody or tutorship. The Iranian legal system, same as the Shia Jurisprudence, has always kept the best Interest of the child as an essential ground for law making. Referring to court decisions; it is evident that control of the guardianship on the child is limited by the best interests of the child, because this interests is what we are sure to understand from the reason of custody of the child and that this system is designed only to secure child’s best interests since he/she might be incapable to secure his/her interests alone. The Iranian legal system, especially in the family law section is based on the Islamic rules. The main documents in the Shia Jurisprudence in Islam are Quran, Hadith, Consensus and reasoning which will be defined herein. In addition, a more recent review will be made in this study regarding the ratified laws regarding children’s rights and international treaties and conventions while focusing on the Convention on the Rights of the Child even though, Iran joined this convention by having several reservations.

Published: July 2019

Background: Glenohumeral instability is common in athletes. There are an estimated 0.12 episodes of instability per 1000 sporting exposures. Instability can lead to time away from sport and an increased risk of shoulder arthritis. Purpose: To determine the prevalence, demographic data, anatomic features, and likelihood of surgery for the different types of instability as defined by the FEDS (frequency, etiology, direction, and severity) classification system for different sports. Study Design: Cohort study; Level of evidence, 3. Methods: Databases at 3 institutions (University of Iowa, Vanderbilt University, and University of Pennsylvania) were searched for International Classification of Diseases--Ninth Revision codes related to shoulder instability in 2010. Demographic data, symptoms, causes, imaging findings, and operative reports were obtained. Data were entered into a custom-designed REDCap online survey. Patients with subjective instability related to sporting activities were included for analysis. Results: A total of 184 athletes had glenohumeral instability; 20.1% were female. The mean age at the time of the first instability episode was 19.0 years for both male and female patients. The most common sports were football (29.3%), basketball (19.0%), and wrestling (9.8%). The most common type of instability based on the FEDS system was occasional, traumatic, anterior dislocation. Surgery was performed on 69.6% of athletes, and 14.1% had a recurrence of instability after surgery overall. Football had the highest rate of recurrence postoperatively at 23.8%. There was no difference in surgery rates between athletes with subluxations versus dislocations ( P = .8458). Surgery was significantly more likely in those with frequent dislocations ( P < .0001) and posterior instability ( P = .027). There was a 10.7% recurrence rate overall with conservative treatment. Conclusion: Glenohumeral instability most commonly occurs in contact sports, affects male more than female patients, and is most frequently in the anterior direction. Recurrent instability is most common in football players. Attention should be turned to the specific characteristics of each type of instability to determine the best treatment for each athlete.
Residential Counselors and Self Care: A Retrospective Qualitative Study of Archival Interview Data
Authors: Lemmons Rebekah , Zanskas Steve 
Published: July 2019

Objectives: The purpose of this qualitative inquiry was to understand the barriers related to effective self-care for master’s level residential counselors. Methods: Archival interview transcripts of 77 residential counselors were analyzed utilizing a social constructivist lens to identify perceived barriers to effective self-care. Themes related to levels of self-care influences including individual, supervisory, and organizational barriers to effective self-care emerged. Results: Results reflected those themes specifically by indicating that counselors can take steps to actively engage in wellness pursuits to promote self-care. Similarly, supervisors and organizations can enhance or impede a counselor’s ability to engage in self-care. Conclusions: Counselors should select work settings that have both supervisory and organizational supports for self-care. This includes encouraging a culture of wellness through support, development, coverage for time off, and other related areas. Implications show that practices and policies are needed to promote effective self-care across individual, supervisory, and agency domains.

Published: July 2019

AbstractPortuguese gypsum deposits utilized by the cement industry were characterized mineralogically, chemically and technologically for possible application in dermocosmetics. The deposits studied (Loulé, Óbidos and Soure) correspond to small outcrops in diapiric anticline areas. In principle, they represent gypsites which are white, and generally of higher quality for traditional applications (e.g.white cement), or greyish, and generally not adequate for cements and mortars. The analytical methods used to characterize the materials were wet sieving and X-ray sedimentation, X-ray diffraction, X-ray fluorescence spectrometry and assessment of abrasiveness, plasticity, texturometrics (adhesivity and firmness), oil absorption and cooling rate. The Óbidos gypsum displayed greater mineralogical and chemical quality (almost pure calcium sulfate) and had a finer grain size (<63 μm), whereas Loulé and Soure gypsums contain mineralogical impurities (mainly quartz). The Óbidos gypsum shows good characteristics in general for application in dermocosmetics because of its absorption, plasticity, adhesivity, firmness and low abrasiveness.
Surface chemistry, rheology and microstructure of as-received SHCa-1 hectorite gels

Published: July 2019

AbstractThe zeta potential and yield-stress behaviour of gels prepared from as-received SHCa-1 hectorite (Ht) containing 50 wt.% impurities, mainly of calcite, dolomite and quartz, were characterized. The zeta potential is negative in the pH range 4–12. At pH <5, reaction of CaCO3 producing CO2 and Ca2+ increased the solution conductivity significantly and reduced the zeta potential. The buffering effect due to this chemical reaction was also observed in the yield stress–pH characterization below pH 8. Low yield stress was observed below pH 6 and above pH 12. The yield stress peaked at pH ~8, where Ht displayed a zeta potential of –20 mV. The relationship between maximum yield stress and Ht content (wt.%) was linear and was not affected by impurities. The ageing behaviour was characterized by an initial phase of rapid yield-stress increase and then by a phase of gradual increase. The Leong model performed better than the two-parameter glassy polymer ageing model in describing this ageing behaviour. However, the empirical power law model was more accurate. The timescale of the ageing process is long, lasting several days. An open cellular microstructure was observed to form in the gels. Impurities appeared not to interact with or bind to the Ht platelets.

BackgroundLow-intensity psychosocial interventions have been effective in targeting perinatal depression, but relevant mechanisms of change remain unknown.AimsTo examine three theoretically informed mediators of the Thinking Healthy Programme Peer-delivered (THPP), an evidence-based psychosocial intervention for perinatal depression, on symptom severity in two parallel, randomised controlled trials in Goa, India and Rawalpindi, Pakistan.MethodParticipants included pregnant women aged ≥18 years with moderate to severe depression, as defined by a Patient Health Questionnaire 9 (PHQ-9) score ≥10, and were randomised to either THPP or enhanced usual care. We examine whether three prespecified variables (patient activation, social support and mother–child attachment) at 3 months post-childbirth mediated the effects of THPP interventions of perinatal depressive symptom severity (PHQ-9) at the primary end-point of 6 months post-childbirth. We first examined individual mediation within each trial (n = 280 in India and n = 570 in Pakistan), followed by a pooled analysis across both trials (N = 850).ResultsIn both site-specific and pooled analyses, patient activation and support at 3 months independently mediated the intervention effects on depressive symptom severity at 6 months, accounting for 23.6 and 18.2% of the total effect of THPP, respectively. The intervention had no effect on mother–child attachment scores, thus there was no evidence that this factor mediated the intervention effect.ConclusionsThe effects of the psychosocial intervention on depression outcomes in mothers were mediated by the same two factors in both contexts, suggesting that such interventions seeking to alleviate perinatal depression should target both social support and patient activation levels.Declaration of interestNone.

PURPOSE Despite epidemiologic and molecular differences between esophageal and stomach cancers, most published studies have included patients with either disease in a metastatic scenario. We evaluated the safety and effectiveness of chemotherapy in patients with metastatic esophageal cancer in the community setting. PATIENTS AND METHODS We performed a retrospective cohort study of patients with synchronous metastatic esophageal cancer treated at a public hospital between 2008 and 2016. Patients were grouped according to a prescribed chemotherapy protocol: platinum and taxane (group A); platinum and irinotecan (group B); platinum and fluoropyrimidine (group C); and without platinum (group D). RESULTS Of the 1,789 patients with esophageal cancer treated, we included 397 with metastatic disease at presentation. Squamous cell carcinoma was the most frequent histology (78.8%). Median overall survival (OS) was 7 months (95% CI, 6.15 to 7.85 months). Chemotherapy was administered to 285 patients, who reached a median OS of 9.0 months (95% CI, 8.0 to 9.9 months); for 112 patients who did not receive treatment, median OS was 3 months (95% CI, 2.3 to 3.7 months; P < .001). The most used combination was platinum plus irinotecan (A; 55.5%). Disease control with in groups A, B, C, and D was 39.2%, 30.1%, 53% and 14.3%, respectively. Patients in group C reached a median OS of 17 months (95% CI, 13.1 to 20.8 months; P = .034). No differences were observed in median OS obtained with other protocols (9 months). The toxicity profile was different according to chemotherapy, with more severe events (hematologic, diarrhea, and number of days hospitalized) occurring in group B. CONCLUSION Platinum plus paclitaxel or platinum plus irinotecan provided similar OS in community patients, although patients receiving irinotecan experienced more severe events. In the adenocarcinoma population, a fluoropyrimidine plus platinum–based regimen, although less frequently used, had a more favorable toxicity profile, with superior median OS and disease control.
The University as Utopia
Authors: Menon Nivedita 
Published: July 2019

AbstractThis article addresses three interrelated themes: the institutional transformations of Indian universities since India's independence, debates in India over the assumed universality of Western modes of knowledge production and transmission, and the overarching philosophical question of knowledge as such. It argues that the question of power and prejudice acquires a different dimension when we consider the university of the Global South. If our struggle is to recover knowledges buried by history, to subvert existing knowledge formations, and to generate new knowledges out of local histories and practices, then we cannot be training ourselves merely to enter existing fields of settled knowledges that have emerged from the history and location of the Global North. The article concludes with a look at some attempts that have been made to decolonize knowledge in the Indian academy, which draw on resources from the Global South, while opening up both “Western” and “Indian” knowledges to interrogation.

Published: July 2019

Abstract
Heterogeneous catalytic reaction at low temperatures (&lt;500 K) has been proposed and investigated by our group. As described in this report, recent trends of low-temperature catalytic reaction for hydrogen production by reforming and ammonia synthesis are summarized. Furthermore, our findings obtained using surface protonics for these two reactions are introduced. Surface protonics occurs by application of an electric field to a heterogeneous catalyst. It makes low-temperature catalytic reactions possible for hydrogen production and ammonia synthesis.
Reward, Control & Decision-Making in Cannabis Use Disorder: Insights from Functional MRI
Authors: Fatima Hudaisa , Howlett Allyn C. , Whitlow Christopher T. 
Published: July 2019

The recreational consumption of cannabis has increased significantly across the world with an estimated 180 million people currently using. In the United States, 4.1 million are currently diagnosed with cannabis use disorder. Cannabis dependence and abuse was combined into a single entity as a behavioral disorder with a problematic pattern of cannabis use and termed cannabis use disorder by the Diagnostic and Statistical Manual of Mental Disorders. Chronic use of cannabis has been linked with region-specific effects across the brain mediating reward processing, cognitive control and decision-making that are central to understanding addictive behaviors. This review presents a snapshot of the current literature assessing the effects of chronic cannabis use on human brain function via functional MRI. Studies employing various paradigms and contrasting cognitive activation amongst cannabis users and non-users were incorporated. The effects of trans-del-ta-9-tetrahydrocannabinol (Δ9-THC) in marijuana and other preparations of cannabis are mediated by the endocannabinoid system, which is also briefly introduced.
Much variation exists in the current literature regarding the functional changes associated with chronic cannabis use. One possible explanation for this variation is the heterogeneity in study designs, with little implementation of standardized diagnostic criteria when selecting chronic users, distinct time points of participant assessment, differing cognitive paradigms and imaging protocols. As such, there is an urgent requirement for future investigations that further characterize functional changes associated with chronic cannabis use.

Aims The aim of the Scaphoid Magnetic Resonance Imaging in Trauma (SMaRT) trial was to evaluate the clinical and cost implications of using immediate MRI in the acute management of patients with a suspected fracture of the scaphoid with negative radiographs. Patients and Methods Patients who presented to the emergency department (ED) with a suspected fracture of the scaphoid and negative radiographs were randomized to a control group, who did not undergo further imaging in the ED, or an intervention group, who had an MRI of the wrist as an additional test during the initial ED attendance. Most participants were male (52% control, 61% intervention), with a mean age of 36.2 years (18 to 73) in the control group and 38.2 years (20 to 71) in the intervention group. The primary outcome was total cost impact at three months post-recruitment. Secondary outcomes included total costs at six months, the assessment of clinical findings, diagnostic accuracy, and the participants’ self-reported level of satisfaction. Differences in cost were estimated using generalized linear models with gamma errors. Results The mean cost up to three months post-recruitment per participant was £542.40 (sd £855.20, n = 65) for the control group and £368.40 (sd £338.60, n = 67) for the intervention group, leading to an estimated cost difference of £174 (95% confidence interval (CI) -£30 to £378; p = 0.094). The cost difference per participant increased to £266 (95% CI £3.30 to £528; p = 0.047) at six months. Overall, 6.2% of participants (4/65, control group) and 10.4% of participants (7/67, intervention group) had sustained a fracture of the scaphoid (p = 0.37). In addition, 7.7% of participants (5/65, control group) and 22.4% of participants (15/67, intervention group) had other fractures diagnosed (p = 0.019). The use of MRI was associated with higher diagnostic accuracy both in the diagnosis of a fracture of the scaphoid (100.0% vs 93.8%) and of any other fracture (98.5% vs 84.6%). Conclusion The use of immediate MRI in the management of participants with a suspected fracture of the scaphoid and negative radiographs led to cost savings while improving the pathway’s diagnostic accuracy and patient satisfaction.
