Authors: Al Barraj Mohammad M. , Fawaz Mirna , Badr Lina Kurdahi 
Published: June 2019

Background and objective: Having a family member admitted to Intensive Care Unit (ICU) is stressful and confusing for family members. The aim of this study was to assess the perception of family members and nurses of their needs and whether those needs are met in four ICUs in Lebanon.Methods: A descriptive cross-sectional design using the Arabic version of Critical Care Family Need Inventory (CCFNI) and the Needs Met Inventory (NMI) were utilized to investigate the needs of 50 family members of patients and 50 nurses.Results: Seventeen of 30 need items on the CCFNI were significantly different between family members and nurses mostly related to ‘Information’ and ‘Assurance’. Family members also varied significantly on 5 out of 30 items on the NMI mostly related to ‘Support’. There were significant differences in needs between family members in terms of gender, age, and education, and significant differences in perceived needs based on the gender, years of experience, and age of nurses.Conclusions: The findings provide insight for nurses to consider the different needs of families, the effect of socio-demographic variations when providing care, and to be attuned to the needs of family members for understandable information and assurance of the wellbeing of patients in ICUs.

Published: June 2019

Introduction: Concurrent peritoneal dialysis (PD) catheter removal during renal transplantation is controversial, with limited evidence supporting this practice. Our objective was to determine the rate of delayed graft function (DGF) in patients on preoperative PD. Additionally, we sought to identify which patients can safely have their PD catheter removed during transplantation due to a low risk of DGF.
Methods: We conducted a retrospective observational study between June 2011 and December 2015. The primary outcome was the diagnosis of DGF, defined as the need for dialysis within the first week of transplantation. Clinical and transplant factors, including graft type and donor criteria, were assessed for association with the primary outcome. Catheter-related complication rates were also compared between post-transplant PD and hemodialysis (HD).
Results: Of our cohort of 567 patients, 145 patients (25.6%) developed DGF. Obesity (odds ratio [OR] 1.06; 95% confidence interval [CI] 1.00–1.11; p=0.04) and increased perioperative blood loss (OR 1.002; 95% CI 1.000–1.003; p=0.03) were predictors of DGF. Protective factors included living donor (LD) grafts (OR 0.15; 95% CI 0.05–0.49; p=0.002) and intraoperative graft urine production (OR 0.39; 95% CI 0.23–0.65; p<0.001). In our PD cohort, only LD grafts demonstrated lower DGF rates (0 LD vs. 20.8% deceased donor; p=0.003). In terms of post-transplant renal replacement therapy, patients on PD and HD had similar duration of temporary dialysis (one day PD vs. two days HD; p=0.48) and catheter-related complication rates (4.5% PD vs. 2.6% HD; p=0.30).
Conclusions: Carefully selected patients, such as those receiving LD grafts, may benefit from concurrent PD catheter removal.
Prevalence and predictors of cannabis use among men receiving androgen-deprivation therapy for advanced prostate cancer
Authors: Mousa Ahmad , Petrovic Michele , Fleshner Neil E. 
Published: June 2019

Introduction: Prostate cancer patients receiving androgen-deprivation therapy (ADT) often experience a combination of disease symptoms and treatment side effects. The therapeutic use of cannabis to alleviate these side effects has not been studied, despite increasing patient interest. With the increasing availability of cannabis, it is important for clinicians to understand the prevalence, predictors, and perceived benefits of cannabis use among patients with prostate cancer.
Methods: A total of 222 men undergoing ADT were assessed in this two-part study. In part one, the cannabis-use questionnaire was administered to 56 men, probing demographics, usage habits, perspectives, and degrees of symptom relief related to cannabis use. In part two, 191 cryopreserved urine samples were retrieved and analyzed for the presence of tetrahydrocannabidiol (THC) metabolite 11-nor-Δ9-THC-COOH. The respondents were then stratified into two groups, users vs. non-users, and statistical analyses were conducted.
Results: Questionnaire data revealed that 23.2% of surveyed men had recently used cannabis. In contrast, 5.8% of men had detectable levels of THC metabolite in their urine. Combined questionnaire and urine data revealed that cannabis users were significantly younger (p=0.003) and had lower testosterone levels (p=0.003) than non-users. The majority of men experiencing common ADT side effects reported some degree of relief following cannabis use.
Conclusions: Cannabis use among men with advanced prostate cancer receiving ADT is more prevalent than in the general population and the majority of other oncological cohorts. Lower testosterone levels and reported therapeutic benefit among cannabis users warrants confirmation in appropriate clinical trials.
Um Areópago histórico: o IHGMG em seus primeiros anos (1907-1913)
Authors: Costa Antonio Carlos Figueiredo 
Published: June 2019

O artigo tem como proposta a trajetória do Instituto Histórico e Geográfico de Minas Gerais durante os seus primeiros anos de existência, toma como ponto de partida a sua fundação, e assume como objetivos evidenciar, com base em pesquisa documental e bibliográfica, a intrínseca relação mantida à época entre a política e a constituição do saber histórico, bem como contribuir para o resgate de algumas da principais temáticas que estiveram presentes em um contexto de historiografia fundante e de compleição ainda fundamentalmente oitocentista. No desenvolvimento do trabalho foram empregadas algumas das usuais metodologias da história social, o que contempla o mais amplo panorama da escrita da História, com incorporação analítica de conceitos antropológicos e sociológicos que visam a permitir na análise histórica da sociedade objeto do estudo, a verificação do agenciamento de setores, bem como de suas expressões e identidades culturais e políticas. A fundação do Instituto Histórico e Geográfico de Minas Gerais teria permitido que uma intelligentsia regional descortinasse, pela via da pesquisa histórica, a representação do passado mineiro mais afeito aos interesses políticos da oligarquia do Estado, contribuindo com isso para a justificação da hegemonia mineira no jogo político da Primeira República.

Published: June 2019

Background: The WRKY transcription factor family plays critical roles in many aspects of physiological processes and adaption to environment. Although the WRKY genes have been widely studied in various plants, the structure and function of the WRKY family in sugar beet (Beta vulgaris L.) remains unknown.
Methods: In the present study, the WRKY genes were identified from the sugar beet genome by bioinformatics. Phylogenetic tree was constructed by MEGA7.0 software. Distribution map of these genes was displayed by MapInspect 1.0. Furthermore, the exon-intron structure and the conserved motifs were predicted by GSDS 2.0 and MEME 5.0.5, respectively. Additionally, the expression levels of these genes under alkaline stress were assayed by qRT-PCR.
Results: A total of 58 putative BvWRKY genes are identified in the sugar beet genome. The coding sequence of these genes ranged from 558 to 2,307 bp and molecular weight varied from 21.3 to 84. Based on the conserved WRKY domain and zinc-finger motif, the BvWRKY genes are clustered into three major groups I, II and III, with 11, 40 and 7 genes, respectively. The number of intron in the BvWRKY genes ranged from 1 to 5, with majority of BvWRKY (27/58) containing three exons. All the BvWRKY genes have one or two WRKY motifs at the N-terminus. Moreover, the expression levels of BvWRKY genes are increased remarkedly by alkaline stress. Our findings extend understandings of the BvWRKY genes family and provide useful information for subsequent research on their functions in sugar beet under alkaline stress.
Modeling of Returns Volatility using GARCH(1,1) Model under Tukey Transformations

Published: June 2019

This study proposed two new classes of GARCH(1,1) model by applying the Tukeytransformations to the returns and to the lagged variance. The behavior of return volatility was investigated on the basis of models with normal and Student-t distributions for return error. The competing models were estimated by using the Excel Solver and Matlab tools. The empirical analysis is based on simulated data, daily exchange rates of the IDR/USD, and daily stock indices of FTSE100 and TOPIX. This study recommends the use of Excel Solver for finance academics and practitioners working on volatility using GARCH(1,1) models. Our empirical findings conclude that GARCH(1,1) models under Tukey transformations should be considered in risk management decisions since the models are more appropriate than standard for describing returns and volatility of financial time series and its stylized facts including fat tails and mean reverting. The Tukey transformed returns imply a shorter volatility half-life, and thus this study suggests that investors should invest the observed assets in a shorter time period to obtain higher returns.

Published: June 2019

AbstractThis research examines the role of adult and lifelong learning in facilitating successful aging among Chinese older adults. A life history research is adopted to conduct the study. By analyzing narratives of research participants’ learning stories, the study explores the provision of lifelong learning programs, Chinese perspectives on successful aging, and contributions of lifelong learning to successful aging and active citizenship among Chinese retired older adults. The findings show that the Chinese perspective on successful aging is closely connected to Chinese culture and traditions. Learning contributes to successful aging by bringing out older adults who are healthier and more independent, open‐minded, and socially active. The rich descriptions of historical and political events, Chinese traditions, moralities, and social values contribute to the understanding of Chinese older adults’ pursuit of lifelong learning and perspectives on successful aging. The detailed discussion of the motives and activities of older adults volunteering advances our extant knowledge about Chinese older adults’ volunteerism.China faces an aging population and adult and lifelong learning contributes to successful aging by bringing out older adults who are healthier and more socially active.

AbstractA variety of spirofluorenyl‐β‐lactams have been prepared in moderate yields over three steps from N‐aryl fluorenone nitrones and methylenecyclopropanes through a [3+2] cycloaddition, reduction and subsequent acid‐catalyzed ring contraction cascade strategy under mild reaction conditions. Experimental studies showed that the stereochemistry remained intact after the ring contraction step. Furthermore, the obtained spirofluorenyl‐β‐lactam was easily converted to two novel spiroazetidine and spiroquinolinone scaffolds in good yields.magnified image
Domino C−S/C−N Bond Formation Using Well‐Defined Copper‐Phosphine Complex Catalyst: Divergent Approach to 3‐Sulfenylated Indoles
Authors: Tamargo Ramuel John Inductivo , Kim Sung Hong , Lee Yong Rok 
Published: June 2019

AbstractA protocol was developed for the synthesis of 3‐thioindoles in good‐to‐excellent yields involving sulfenylation between 2‐nitrocinnamaldehydes and various thiols using a well‐defined copper(I)‐phosphine complex catalyst. This unconventional divergent approach involves in situ generation of indoles via domino C−S/C−N bond formation initiated by sulfa‐Michael addition followed by intramolecular N‐heteroannulation. This protocol shows good chemoselectivity and broad substrate scope. To briefly demonstrate the value of this approach, 2‐benzoyl‐3‐sulfenylated indoles were prepared from commercially available 2‐nitrochalcones and thiols.magnified image

Published: June 2019

AbstractPotassium‐ion batteries (KIBs) are one of the most appealing alternatives to lithium‐ion batteries, particularly attractive in large‐scale energy storage devices considering the more sufficient and lower cost supply of potassium resources in comparison with lithium. To achieve more competitive KIBs, it is necessary to search for anode materials with a high performance. Herein, the bimetallic oxide Sb2MoO6, with the presence of reduced graphene oxide, is reported as a high‐performance anode material for KIBs in this study, achieving discharge capacities as high as 402 mAh g−1 at 100 mA g−1 and 381 mAh g−1 at 200 mA g−1, and reserving a capacity of 247 mAh g−1 after 100 cycles at a current density of 500 mA g−1. Meanwhile, the potassiation/depotassiation mechanism of this material is probed in‐depth through the electrochemical characterization, operando X‐ray diffraction, transmission electron microscope, and density functional theory calculation, successfully unraveling the nature of the high‐performance anode and the functions of Sb and Mo in Sb2MoO6. More importantly, the phase development and bond breaking sequence of Sb2MoO6 are successfully identified, which is meaningful for the fundamental study of metal‐oxide based electrode materials for KIBs.
Medical data mining: The search for knowledge in workers' compensation claims
Authors: Wrona Ronald M. 
Published: June 2019

AbstractWorkers’ compensation claims data are an underutilized source of research data. Data mining is a step in the process of knowledge discovery. This report is an inquiry into the question of whether data mining can be used to expand the research potential of workplace injury claims. A descriptive data‐mining method is used to avoid the hazards of predictive data mining. A key decision in descriptive data mining is the selection of the descriptive variables to be included. A major purpose of claims processing is documentation of benefit decisions. This documentation is used in selecting the case records embedded in a claim history. This novel process is called beneficiation not only because of the obvious reference to benefit but also because it is a mining term that describes a process that further refines metallic ores.Claim beneficiation identified four data forms that contain descriptive information about workplace injury claim data. They are the first report of injury, the activity prescription form, a functional capacity evaluation, and a physical capability estimate. When the data variables from these forms are combined they become a workplace injury case registry history which is a new frontier for research in injury epidemiology.

Published: June 2019

AbstractThe first examples of rare‐earth polyiodates, namely, REI5O14 (RE=Y and Gd), have been prepared by hydrothermal reactions of RE2O3 and H5IO6 in H3PO4 (≥85 wt % in H2O), with extremely high yields (>95 %). They crystalize in the polar space group Cm and feature a brand‐new semicircle‐shaped [I5O14]3− pentameric polyiodate anion composed of two IO3 and three IO4 polyhedra. Remarkably, both compounds exhibit very large second‐harmonic generation (SHG) signals (14× and 15×KH2PO4 (KDP) upon 1064 nm laser radiation for Y and Gd compounds, respectively). Our work shows that the hydrothermal reaction in a phosphoric acid medium facilitates the formation of rare‐earth polyiodates.

AbstractThe modulation of electron density is an effective option for efficient alternative electrocatalysts. Here, p‐n junctions are constructed in 3D free‐standing FeNi‐LDH/CoP/carbon cloth (CC) electrode (LDH=layered double hydroxide). The positively charged FeNi‐LDH in the space‐charge region can significantly boost oxygen evolution reaction. Therefore, the j at 1.485 V (vs. RHE) of FeNi‐LDH/CoP/CC achieves ca. 10‐fold and ca. 100‐fold increases compared to those of FeNi‐LDH/CC and CoP/CC, respectively. Density functional theory calculation reveals OH− has a stronger trend to adsorb on the surface of FeNi‐LDH side in the p‐n junction compared to individual FeNi‐LDH further verifying the synergistic effect in the p‐n junction. Additionally, it represents excellent activity toward water splitting. The utilization of heterojunctions would open up an entirely new possibility to purposefully regulate the electronic structure of active sites and promote their catalytic activities.

Published: June 2019

AbstractThe stabilization of peptide secondary structure via stapling is a ubiquitous goal for creating new probes, imaging agents, and drugs. Inspired by indole‐derived crosslinks found in natural peptide toxins, we employed ortho‐phthalaldehydes to create isoindole staples, thus transforming inactive linear and monocyclic precursors into bioactive monocyclic and bicyclic products. Mild, metal‐free conditions give an array of macrocyclic α‐melanocyte‐stimulating hormone (α‐MSH) derivatives, of which several isoindole‐stapled α‐MSH analogues (Ki≈1 nm) are found to be as potent as α‐MSH. Analogously, late‐stage intra‐annular isoindole stapling furnished a bicyclic peptide mimic of α‐amanitin that is cytotoxic to CHO cells (IC50=70 μm). Given its user‐friendliness, we have termed this approach FlICk (fluorescent isoindole crosslink) chemistry.

Published: June 2019

Condensation of 2,5‐dihydrazinyl thiadiazole with 5‐sodium sulfonate salicylaldehyde afforded dibasic tetradentate pincer N,O,O,N‐salicyldiene thiadiazole ligand (H2Sanp). The novel dipolar ligand formed para‐magnetic pincer complexes within Co (II) and Ni (II) ions (Co‐Sanp and Ni‐Sanp) under sustainable conditions. The water‐soluble ligand and its metal‐complexes were estimated by mass, IR and UV–Visible spectroscopy, EA (elemental analyses), TGA (Thermogravimetric analyses), magnetic susceptibility, and conductivity measurements. The catalytic reactivity of Co‐Sanp and Ni‐Sanp were evaluated in the Suzuki and Buchwald‐Hartwig cross coupling reaction in aqueous‐methanol binary mixtures. Both reactions of boronic acid or aryl amines with aryl halides gave high chemoselective yield of C―C or C―N product. The inhibition characteristics of H2Sanp and its Ni‐ and Co‐complexes were performed for the C‐steel corrosion in 1.0 M HCl using electrochemical measurements and surface analysis methods. These methods indicated that the synthesized compounds have served as efficient mixed‐type corrosion inhibitors and their adsorption on the steel surface obeyed isotherm model of Langmuir. Co‐Sanp inhibitor displays the best corrosion inhibition efficiency, and the capacity is up to 97.11% at of 250 mg L−1. Surface analysis confirms formation of protective layer on the C‐steel surface.

A MnO2/CdTiO3 is prepared by a simple chemical method. The organic compound such as antibiotics is a contaminant found in large amounts in pharmaceutical industrial wastewater. Pharmaceutical compounds are toxic. The nano‐product was characterized by SEM, XRD, XPS, DLS and UV–vis DRS revealed that the MnO2 nanoparticles were supported on the CdTiO3 surface. The crystallite size was found as 72.11 nm, and 38.13 nm for CdTiO3, and MnCdTi‐1 nanocomposites, respectively. The prepared catalyst was used for photo‐degradation of cephalexin under UV light irradiation. The result implies the complete degradation of cephalexin was carried out at 80 min for MnCdTi‐2 nanocomposites (88.88%) due to this catalyst has the lowest band gap compared to the other catalyst. The MnO2/CdTiO3 was selected for fungicidal and bactericidal efficiency against Aspergillus flavus, and candida albicans and Escherichia coli, and Staphylococcus aureus. The MnO2/CdTiO3–2 has great activity is compared with the other MnO2/CdTiO3–0 and MnO2/CdTiO3–1 samples.

Published: June 2019

AbstractSound Masking, sprich das Einbringen eines definierten Geräusches in eine Bürofläche, kann die Störwirkung durch Hintergrundsprache verringern. Konventionelle Sound Masking‐Systeme bestehen meist aus in der Decke eingebauten Lautsprechern in einem Raster von 2–4 m. Personalisierte Sound Masking Systeme, bei denen Lautsprecher lokal in Arbeitsplatznähe positioniert sind, sind bislang wenig erforscht. Bei solchen Systemen beeinflusst die Positionierung der Lautsprecher die Wirksamkeit. Der Aufsatz beschreibt die Ergebnisse eines Hörversuchs, der in einem Mehrpersonenbüro in laborähnlichen Bedingungen durchgeführt wurde. Die Versuchsteilnehmer bearbeiteten eine Aufgabe zur Messung der Kurzzeitgedächtnisleistung und einen Fragebogen unter zwölf Schallbedingungen. Die kognitive Leistung der Versuchspersonen war niedriger, wenn das Maskierungssignal und die Sprache aus unterschiedlichen horizontalen Richtungen anstatt aus der gleichen Richtung wiedergegeben wurden. Ein ähnlicher Effekt wurde beobachtet, wenn das Maskierungssignal über ein konventionelles System mit Deckenlautsprechern wiedergegeben wurde. Dieser Nachteil trat nicht auf, wenn die Deckenlautsprecher auch zwischen 100 und 200 Hz Schallenergie abgaben. Da die Maskierung mit konventionellen Deckenlautsprechern weder zu niedrigeren Fehlerraten führte noch als weniger lästig bewertet wurde, kann daraus geschlossen werden, dass das personalisierte Sound Masking‐System genauso wirksam wie das konventionelle System war.
