Building Arc Crust: Plutonic to Volcanic Connections in an Extensional Oceanic Arc, the Southern Alisitos Arc, Baja California
Authors: Morris Rebecca A , DeBari Susan M , Busby Cathy , Medynski Sarah , Jicha Brian R 
Published: May 2019

AbstractThe ∼50 km long Rosario segment of the Cretaceous Alisitos oceanic arc terrane provides undeformed three-dimensional exposures of the upper 7 km of an oceanic extensional arc, where crustal generation processes are recorded in both the volcanic and underlying plutonic rocks. These exceptional exposures allow for the study of the physical and chemical links between the rock units and help constrain the differentiation processes active during the growth and evolution of arc crust. This study focuses on the southern third of the Rosario segment, previously referred to as the southern volcano-bounded basin, and its plutonic underpinnings. Upper crustal rocks in the Rosario segment consist of a 3–5 km thick volcanic–volcaniclastic section with hypabyssal intrusions. Plutons intrude these units at various levels along-strike, but at each intrusive contact the transition is complete over a distance of <150 m, where stoped volcanic blocks are present. There is striking compositional overlap in whole-rock and mineral chemistry between the plutonic and volcanic units, suggesting a comagmatic source. Whole-rock geochemistry shows coherent trends in major and trace elements in mafic to intermediate compositions, but less coherent trends above 63 wt % SiO2. Units are predominantly low-K with flat rare earth element patterns, and show large ion lithophile element enrichment and high field strength element depletion. Initial Nd and Pb isotope ratios overlap for all units and imply no cratonic continental involvement. This agrees with low Sr/Y ratios of all rock types, indicative of thin, immature oceanic arc crust. Modeling results show that closed-system fractional crystallization drove crustal differentiation from mafic to intermediate compositions, but open-system processes likely occurred to produce some of the felsic compositions. Differentiation occurred in a two-step fractionation process. Step 1, from basaltic andesite to andesite, fractionated an anhydrous gabbroic cumulate (∼40% crystallization). Step 2, from andesite to rhyolite, fractionated a hydrous amphibole cumulate (∼65% crystallization, total), which is similar to what fluid dynamical models suggest for production of rhyolite (between 50–70% crystallization). Our results can be used as a reference model for differentiation processes relating to the growth of the middle and upper crust within active extensional arc systems. The Rosario segment plutonic rocks may be analogous to the low-velocity zone (Vp = 6·0–6·5 km s–1) imaged within the extensional Izu–Bonin arc. The chemistry of the plutonic and volcanic rocks is most similar to those of volcanic rocks in the Izu–Bonin active rift.
Irregular parameter dependence of numerical results in tensor renormalization group analysis
Authors: Kadoh Daisuke , Kuramashi Yoshinobu , Ueno Ryoichiro 
Published: May 2019

Abstract
We study the parameter dependence of numerical results obtained by the tensor renormalization group. We often observe irregular behavior as the parameters are varied with the method. Using the two-dimensional Ising model we explicitly show that the sharp cutoff used in the truncated singular value decomposition causes this unwanted behavior when the level crossing happens between singular values below and above the truncation order as the parameters are varied. We also test a smooth cutoff, instead of the sharp one, as a truncation scheme and discuss its effects.
Dash for Cash: Monthly Market Impact of Institutional Liquidity Needs
Authors: Etula Erkko , Rinne Kalle , Suominen Matti , Vaittinen Lauri 
Published: May 2019

Abstract
We present broad-based evidence that the monthly payment cycle induces systematic patterns in liquid markets around the globe. First, we document temporary increases in the costs of debt and equity capital that coincide with key dates associated with month-end cash needs. Second, we present direct and indirect evidence on the role of institutions in the genesis of these patterns and derive estimates of the associated costs borne by market participants. Third, and finally, we investigate the limits to arbitrage that prevent markets from functioning efficiently. Our results indicate that many investors and their agents, including mutual funds, suffer from liquidity-related trading.

Latent Trade Diversification and Its Relevance for Macroeconomic Stability
Authors: Lederman Daniel , Pienknagura Samuel , Rojas Diego 
Published: May 2019

Abstract
This paper examines the economic implications of a novel concept of trade diversification—latent diversification. In contrast to traditional measures, latent diversification accounts for potential movements of factors of production into activities where the country has previous exporting experience, hence presenting an additional margin through which countries can respond to shocks. The paper shows that the gap between traditional measures of diversification and latent diversification is sizeable and that latent diversification is in its own right an important determinant of macroeconomic stability. More diversified latent export baskets are associated with lower terms-of-trade volatility and, in turn, lower GDP per capita volatility, even after controlling for the degree of contemporaneous export diversification and other country characteristics.
Mitochondrial genome reorganization provides insights into the relationship between oribatid mites and astigmatid mites (Acari: Sarcoptiformes: Oribatida)
Authors: Li Wei-Ning , Xue Xiao-Feng 
Published: May 2019

AbstractOribatida s.l. represents one of the most species-rich mite lineages, including two recognized groups: oribatid mites (Oribatida s.s., non-astigmatan oribatids) and astigmatid mites (Astigmata). However, the relationship between these two groups has been debated. Here, we sequenced the complete mitochondrial (mt) genome of one oribatid mite and one astigmatid mite, retrieved complete mt genomes of three oribatid mites, and compared them with two other oribatid mites and 12 astigmatid mites sequenced previously. We find that gene orders in the mt genomes of both oribatid mites and astigmatid mites are rearranged relative to the hypothetical ancestral arrangement of the arthropods. Based on the shared derived gene clusters in each mt genome group, rearranged mt genomes are roughly divided into two groups corresponding to each mite group (oribatid mites or astigmatid mites). Phylogenetic results show that Astigmata nested in Oribatida. The monophyly of Astigmata is recovered, while paraphyly of Oribatida s.s. is observed. Our results show that rearranged gene orders in the mt genomes characterize various lineages of oribatid mites and astigmatid mites, and have potential phylogenetic information for resolving the high-level (cohort or supercohort) phylogeny of Oribatida.

Published: May 2019

OBJECTIVE:
To determine the effect of tubal ligation on age at natural menopause, as a marker of long-term ovarian function.

METHODS:
Three preexisting population-based cohorts were included in this cross-sectional study. Data from each cohort was analyzed separately. The cohorts were restricted to women who never smoked and had reached natural menopause, without prior hysterectomy or oophorectomy. The following variables were collected: race, age at menarche, age at menopause, history of hysterectomy or oophorectomy, gravidity and parity, tobacco use, and ever use of hormonal contraception. The type of tubal ligation and age at tubal ligation were manually abstracted in cohort 1. For cohorts 2 and 3, history of tubal ligation was obtained from an institutional form, completed by patient report. The primary outcome, age at natural menopause, was compared between the two groups (those with and without a history of tubal ligation).

RESULTS:
Inclusion criteria was met by 555 women from cohort 1, 1,816 women from cohort 2, and 1,534 women from cohort 3. Baseline characteristics did not differ between cohorts. The percentage with tubal ligation was the same in all cohorts: 26.0%, 25.5%, and 25.0%, respectively. Women with a tubal ligation were more likely to have had at least one pregnancy and to have used hormonal contraception compared with women without a tubal ligation. There was no significant difference in age at natural menopause in women who underwent tubal ligation (50.1, 49.9, 50.0 years, respectively) compared with those who did not (50.7, 49.6, 50.0 years, respectively). The type of tubal ligation (cohort 1 only) had no effect on age at menopause.

CONCLUSIONS:
Tubal ligation did not affect age at natural menopause in the three large cohorts included in this study.

Published: May 2019

OBJECTIVE:
Drug-induced deaths, defined as intentional or unintentional consumption of illicit substances or diverted medications leading to death, are the leading cause of death for reproductive-age women in the United States. Our objective was to describe pregnancy-associated deaths attributed to drug-induced causes to identify opportunities for intervention.

METHODS:
Using the Utah Perinatal Morality Review Committee database, we performed a retrospective cohort study of all pregnancy-associated deaths—death of a woman during pregnancy or within 1 year from the end of pregnancy—from 2005 to 2014. We performed a detailed descriptive analysis of women with drug-induced deaths. We compared characteristics of women with drug-induced and other pregnancy-associated deaths.

RESULTS:
From 2005 to 2014, 136 pregnancy-associated deaths were identified. Drug-induced death was the leading cause of pregnancy-associated death (n=35, 26%) and 89% occurred in the postpartum period. More specifically, those with a drug-induced death were more likely to die in the late postpartum period, defined as death occurring within 43 days to 1 year of the end of the pregnancy, (n=28/35, 80%) compared with women whose deaths were from other pregnancy-associated causes (n=34/101, 34%) (P<.001). The majority of drug-induced deaths were attributed to opioids (n=27/35, 77%), prescription opioids (n=21/35, 60%), and polysubstance use (n=29/35, 83%). From 2005 to 2014, the pregnancy-associated mortality ratio increased 76%, from 23.3 in 2005 to 41.0 in 2014. During this same time period, the drug-induced pregnancy-associated mortality ratio increased 200%, from 3.9 in 2005 to 11.7 in 2014.

CONCLUSION:
Drug-induced death is the leading cause of pregnancy-associated death in Utah and occurs primarily in the late postpartum period. Interventional studies focused on identifying and treating women at risk of drug-induced death are urgently needed.
Understanding Articular Cartilage Injury and Potential Treatments

Published: May 2019

Summary:
The goals of all orthopaedic surgeons treating articular cartilage injuries have been anatomic reduction and stable fixation of the articular cartilage surface with restoration of limb alignment and/or reestablishment of the joint stability, all while minimizing the risk of surgical complications. Recent developments in the study of articular cartilage injury have shown that there is a robust cellular response to joint injury. This response has been shown to involve the synoviocytes, chondrocytes, and osteocytes in and around the injured joint and if these responses are left unchecked, they can lead to the development of posttraumatic osteoarthritis (PTOA). Therefore, to predictably and successfully treat articular cartilage injuries, it is not sufficient to just restore articular congruity, limb alignment, and joint stability, but we must also recognize and attempt to mitigate this associated cellular response. Understanding not only the mechanical aspects of these joint injuries but also the biological aspects is paramount to giving our patients the best opportunity to heal their injuries, recover full function, and avoid the potential devastating development of PTOA. Gone is the simplistic view that if one can achieve articular congruity after intraarticular fracture, as well as joint stability after ligamentous injury, that our patients will do just fine. This review sheds new light on the molecular response to cartilage injury, how residual joint incongruity and instability affect the joint's ability to recover from injury, and how chondrocyte apoptosis in response to injury can influence joint. This article then briefly reviews how cellular and growth factors may be beneficial to the treatment of articular cartilage injury and how ultimately cartilage regeneration may be used in the future to salvage the joints ravaged by PTOA in response to injury.
A New and More Sensitive View for the Detection of Syndesmotic Instability
Authors: Gosselin-Papadopoulos Nayla , Hébert-Davies Jonah , Laflamme Georges-Yves , Ménard Jérémie , Leduc Stéphane , Nault Marie-Lyne 
Published: May 2019

Objectives:
We hypothesize that a single syndesmotic view, capturing both sagittal and coronal tibiofibular displacement, will be more sensitive than a mortise view to detect syndesmotic instability.

Methods:
Ten fresh frozen human lower limbs were used to test the new syndesmotic view with simulated syndesmosis injury. The anteroinferior tibiofibular ligament, interosseous membrane, and posteroinferior tibiofibular ligament were sectioned sequentially. At each stage, the syndesmosis was tested using the external rotation stress (ERS) test and lateral stress test (LST). For each stress condition, a true mortise view and the new syndesmotic view were performed. Medial clear space and tibiofibular clear space (TFCS) were measured on a mortise view, and TFCS was measured on a syndesmotic view (TFCS-s). Wilcoxon signed-rank tests were used to compare measurements.

Results:
Syndesmotic view enabled instability detection with a 2-ligament dissection at a mean increase in TFCS-s of 2.37 mm (P = 0.021) and 1.98 mm (P = 0.011), using the ERS and LST, respectively. TFCS on the mortise view was significantly different only with a complete injury. Medial clear space did not vary significantly with injury increments. Sensitivity was 66% and 61% using ERS and LST, respectively, for the TFCS-s, compared with 27% and 33%, respectively, for the TFCS. Specificity was similar for TFCS and TFCS-s.

Conclusions:
This study was able to demonstrate that the syndesmotic view is more sensitive than the mortise view in detecting syndesmotic instability in a cadaveric model. It is particularly helpful to uncover instability secondary to an incomplete syndesmosis injury requiring fixation.
Encountering Patient Suicide During Psychiatric Training: An Integrative, Systematic Review
Authors: Leaune Edouard , Ravella Noémie , Vieux Maxime , Poulet Emmanuel , Chauliac Nicolas , Terra Jean-Louis 
Published: May 2019

Background/aim
Patient suicide is an adversity that can be considered an “occupational hazard.” It has been identified as one of the most stressful adverse events during psychiatric training. The aim of this study was to systematically review the literature assessing the impact of patient suicide on trainees.

Methods
We conducted a systematic review on the MEDLINE, Science Direct, Scopus, and Web of Science databases. Studies that reported prevalence of patient suicide, quantitative or qualitative assessment of psychological and professional impacts, coping strategies, and support or educational and postvention programs were deemed eligible for inclusion.

Results
Of the 1994 articles identified, 22 were included. The literature on the topic was scarce, and the quality of the studies was moderate. No article dealt with nonpsychiatric residents. During their training, 46.4% of psychiatric trainees encountered at least one patient suicide. The traumatic impact was significantly more intense in trainees compared to senior physicians. A negative impact on their professional practice was reported by 17% to 39% of trainees. Formal institutional support for the affected trainees was described as having major shortcomings, and informal support from peers and families was reported as the most helpful response. However, 52% of impacted trainees considered encountering patient suicide a useful and beneficial experience.

Conclusion
The frequent posttraumatic symptoms and the negative professional consequences following patient suicide are worrying phenomena that highlight the need to improve suicide prevention and postvention programs during psychiatric training. Identifying trainees with personal vulnerability factors should be a major concern during the postvention process.

Published: May 2019

Abstract

Rationale:
Post-stroke cognitive impairment occurs frequently in patients with stroke, with a 20% to 80% prevalence. Anxiety is common after stroke, and is associated with a poorer quality of life. The use of standard relaxation techniques in treating anxiety in patients undergoing post-stroke rehabilitation have shown some positive effects, whereas virtual reality seems to have a role in the treatment of anxiety disorders, especially when associated to neurological damage.

Patients concerns:
A 50-year-old woman, smokers, affected by hypertension and right ischemic stroke in the chronic phase (i.e., after 12 months by cerebrovascular event), came to our observation for a severe anxiety state and a mild cognitive deficit, mainly involving attention and visuo-executive processes, besides a mild left hemiparesis.

Diagnosis:
Anxiety in a patient with ischemic stroke.

Interventions:
Standard relaxation techniques alone in a common clinical setting or the same psychological approach in an immersive virtual environment (i.e., Computer Assisted Rehabilitation Environment – CAREN).

Outcomes:
The patient's cognitive and psychological profile, with regard to attention processes, mood, anxiety, and coping strategies, were evaluated before and after the 2 different trainings. A significant improvement in the functional and behavioral outcomes were observed only at the end of the combined approach.

Lessons:
The immersive virtual reality environment CAREN might be useful to improve cognitive and psychological status, with regard to anxiety symptoms, in post-stroke individuals.
Utilization of the directional balloon technique to improve the effectiveness of percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fractures and reduction of bone cement leakage
Authors: Wang Pu , Li Jin , Song Zukun , Peng Zhan , Wang Guangye 
Published: May 2019

Abstract

Background:
This article evaluates the effectiveness of a new directional balloon technique in the treatment of osteoporotic vertebral compression fractures (OVCFs).

Methods:
From September 2015 to April 2017, 100 patients with single-segment OVCFs treated using percutaneous kyphoplasty were available for complete data assessment. Among these, 51 cases were treated with the traditional nondirectional balloon technique (group 1) and 49 cases were treated with the directional balloon technique (group 2). Operative time, blood loss, and X-ray exposure time were compared between the 2 groups. The visual analogue score (VAS), Oswestry disability index (ODI), and Roland Morris disability (RMD) scores, and wedge-shaped and kyphosis angles were measured at 3 days and 1, 3, 6, and 12 months, respectively, after surgery.

Results:
There were no significant differences in blood loss or the amount of bone cement injected between the 2 groups; however, operative times, X-ray exposure times, and leakage rates of bone cement, especially type C in group 2, were significantly lower in group 2 than those in group 1. VAS, ODI, and RMD scores, and wedge-shaped and kyphosis angles at each time point after surgery were significantly higher than those before surgery. However, the improvement in VAS, ODI, and RMD scores in group 2 was only significantly better than those in group 1 at 3 days after surgery.

Conclusion:
The utilization of the directional balloon technique in the treatment of OVCFs using percutaneous kyphoplasty can not only reduce the operation time, the radiation, and the bone cement leakage, but also improve the early curative effect.
The effect of vitamin D3 on blood pressure in people with vitamin D deficiency
Authors: He Silu , Hao Xiyuan 
Published: May 2019

Abstract

Objective:
To evaluate the effect of vitamin D3 on blood pressure in people with vitamin D deficiency.

Methods:
Randomized controlled trials (RCTs) were electronically searched databases including CNKI, VIP, WanFang Data, the Cochrane Library, PubMed, and EMbase which were about oral vitamin D3 among people with vitamin D deficiency from inception to December 2017. Two reviewers independently screened literature according to the inclusion and extracted data; meta-analysis was performed using RevMan5.3.

Results:
A total of 17 RCTs with 22 arms involving 1687 participants were included. The results of meta-analysis showed that, there were no significant differences between the vitamin D deficiency group and the control group on the level of change in systolic pressure (ΔSBP) [weighted mean difference (WMD) = −1.94, 95% confidence interval (CI) (−3.93,0.04) P = .06] and on the level of change in diastolic pressure (ΔDBP) [WMD = −0.50, 95% CI (−1.17, 0.17) P = .14]. The results of subgroups showed that, there were statistically significant differences in the age of >50 years subgroup on ΔSBP [WMD = −2.32, 95% CI (−4.39, −0.25) P = .03]; there were statistically significant differences in the hypertension subgroup on ΔSBP [WMD = −6.58, 95% CI (−8.72, −4.44) P <.00001]; there were statistically significant differences in the hypertension subgroup on ΔDBP [WMD = −3.07, 95% CI (−4.66, −1.48) P = .0002]; there were statistically significant differences in the body mass index (BMI) >30 subgroup on ΔSBP [WMD = −3.51, 95% CI (−5.96, −1.07) P = .005].

Conclusion:
Oral vitamin D3 has no significant effect on blood pressure in people with vitamin D deficiency. It reduces systolic blood pressure in people with vitamin D deficiency that was older than 50 years old or obese. It reduces systolic blood pressure and diastolic pressure in people with both vitamin D deficiency and hypertension.
