Socially Nudged: A Quasi-Experimental Study of Friends’ Social Influence in Online Product Ratings
Authors: Wang Chong (Alex) , Zhang Xiaoquan (Michael) , Hann Il-Horn
Published: May 2018

Social-networking functions are increasingly embedded in online rating systems. These functions alter the rating context in which consumer ratings are generated. In this paper, we empirically investigate online friends’ social influence in online book ratings. Our quasi-experimental research design exploits the temporal sequence of social-networking events and ratings and offers a new method for identifying social influence while accounting for the homophily effect. We find that rating similarity between friends is significantly higher after the formation of the friend relationship, indicating that with social-networking functions, online rating contributors are socially nudged when giving their ratings. Exploration of contingent factors suggests that social influence is stronger for older books and for users who have smaller networks, and that relatively more recent and extremely negative ratings cast more salient influence.

Recursos no verbales en comunicación persuasiva: gestos
Authors: Cestero Mancera Ana M.
Published: May 2018

La comunicación humana es un proceso complejo que supone mucho más que conocer y utilizar un sistema lingüístico: la eficacia comunicativa de cualquier acto depende, en mayor o menor medida, de la utilización de signos no verbales en combinación o coestructuración con los verbales. Este hecho constatado es de gran importancia en fenómenos pragmático-discursivos como la persuasión, que puede relacionarse de manera directa con el empleo estratégico de recursos no verbales. En este trabajo se trata lo que acontece con respecto al uso de recursos no verbales quinésicos en el discurso persuasivo español del ámbito de la empresa y los negocios.

Gardenia aqualla a plant of the Rubiaceae family is being used extensively in Africa, particularly in Cameroon as an herbal medicine. Therefore it is necessary to have knowledge of the constituents of the plant of our native species. Thus, the aim of the present study was to investigate chemical constituents of this herbal medicine. Nine compounds, including one alkane, n-Nonacosane (1), two aliphatic alcohols n-heptatriacontanol (2) and n-Docosanol(3), one fatty ester, Heptadecyl heptacosanoate (4), two sugars, D-mannitol (5) and D-mannitol acetate (6), and a mixture of three phytosterols, β-sitosterol (7), stigmasterol (8) and fucosterol (9), have been isolated and purified from the stem barks of Gardenia aqualla Stapf & Hutch. Their structures were elucidated using spectroscopic analyses, including 1D and 2D NMR and ESI-MS. The fatty acid ester, heptadecyl heptacosanoate (4) is reported here for the first time. All the isolated compounds were tested for their antimicrobial activities against four Gram negative bacteria (Salmonella Typhimurium ATCC6539, Pseudomonas aeruginosa ATCC9721, Escherichia coli, and S. Typhi) and four yeasts (Candida albicans ATCC9002, Candida parapsilosis ATCC22019, Candida krusei and C. albicans).
Serum containing drugs of Gua Lou Xie Bai decoction (GLXB-D) can inhibit TGF-β1-Induced Epithelial to Mesenchymal Transition (EMT) in A549 Cells

Published: May 2018

The present study explores the mechanism of resistance to pulmonary fibrosis by observing the possible effects of serum containing drugs prepared from Gua Lou Xie Bai decoction (GLXB-D) on transforming growth factor beta 1 (TGF-β1) induced Epithelial-mesenchymal transition (EMT) of A549 human alveolar epithelial cells. The inhibition rate was observed with the help of thiazolyl blue tetrazolium bromide (MTT) in 24 h and 48 h treated cells. Inverted microscope and transmission electron microscope (TEM) were used to study the changes in the morphology and ultrastructure of the cells. The expressions of E-cadherin and Vimentin were comparatively analyzed by Western blotting, while the expressions of Collagen I and III were analyzed by ELISA. The data obtained indicated that the expression of epithelial marker E-cadherin was decreased, while the expressions of EMT markers such as Vimentin and Collagen I and III were increased in 24 h after TGF-β1 induction. However, the serum containing drugs of GLXB-D were found to inhibit the TGF-β1 induced proliferation of cells, increase the expression of E-cadherin and decrease the expression of Vimentin, collagen I and III. In conclusion, the serum containing drugs of GLXB-D effectively reduced pulmonary fibrosis, mainly via the reversal of EMT induction by TGF-β1. Thus, it can be considered as a potential candidate for the development of better treatment methods for pulmonary fibrosis.
Utility of essential oils for development of host-based lures for Xyleborus glabratus (Coleoptera: Curculionidae: Scolytinae), vector of laurel wilt
Authors: Kendra Paul E. , Montgomery Wayne S. , Niogret Jerome , Tabanca Nurhayat , Owens David , Epsky Nancy D.
Published: May 2018

Redbay ambrosia beetle, Xyleborus glabratus, is native to Southeast Asia, but subsequent to introduction in Georgia in 2002, it has become a serious invasive pest in the USA, now established in nine southeastern states. Females vector Raffaelea lauricola, the fungus that causes laurel wilt, a lethal vascular disease of trees in the family Lauraceae. Laurel wilt has caused extensive mortality in native Persea species, including redbay (P. borbonia), swampbay (P. palustris), and silkbay (P. humilis). Avocado (P. americana) is now impacted in Florida, and with continued spread, laurel wilt has potential to affect avocado and native Lauraceae in California, Mexico, and throughout the American tropics. Effective lures for detection and control of X. glabratus are critical to slow the spread of laurel wilt. No pheromones are known for this species; primary attractants are volatile terpenoids emitted from host Lauraceae. This report provides a concise summary of the chemical ecology of X. glabratus, highlighting research to identify kairomones used by females for host location. It summarizes development of essential oil lures for pest detection, including discussions of the initial use of phoebe and manuka oil lures, the current cubeb oil lure, and a newly-developed distilled oil lure enriched in (-)-α-copaene.

The article assesses whether the compensation in Sweden and the UK is fair in relation to compensation for other necessary social infrastructures such as water and electricity, consideration for equivalent voluntary rights in land, general principles of expropriation law and the right to peaceful enjoyment of property according to Article 1 in the first Protocol of the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR).
Secured credit and partial priority: Corporate finance as a creation or an externalisation practice?
Authors: de Weijs R.J.
Published: May 2018

Four developments warrant revisiting the debate on full priority and taking steps to implement a partial priority system. The first development is that secured credit increasingly results in a complete lack of funds to cover the expenses of the insolvency procedure. The second development is that secured credit is often not doing what the proponents of full priority argue that it is doing, namely facilitating growth. Instead, it is increasingly used to simply facilitate the leverage of the company without any intent to invest in the company. Thirdly, the plight of unsecured creditor is deteriorating in new ways. Trade creditors in particular are increasingly forced into the position of being suppliers of credit, turning non-adjusting creditors into what can be referred to as adjustable creditors. The fourth development is that these trade creditors find insolvency laws increasingly working against them instead of for them.

Published: May 2018

Objective

To investigate the relationship between uric acid and metabolic syndrome (MetS) in elderly women.

Methods

A total of 468 women aged ≥60 years participating in a health examination were enrolled. The association between uric acid and MetS and its individual variables was evaluated by univariate and multivariate logistic regression models.

Results

A dose-response relationship was observed for the prevalence of MetS and uric acid quartiles. Subjects in the second, third and fourth quartile of uric acid had a 2.23-fold, 2.25-fold and 4.41-fold increased risk, respectively, of MetS than those in the first uric acid quartile (p for trend <0.001). Furthermore, each 1 mg/dl increment of serum uric acid level had a 1.38-fold increased risk of MetS (OR 1.38; 95% CI, 1.14-1.69; p=0.001).

Conclusions

Our present study demonstrated that elevated uric acid was positively associated with the prevalence of MetS in elderly women. Further random control trials are needed to elucidate the effectiveness of treatment of hyperuricaemia in reducing the incidence of MetS in elderly women.

Christie CJ, Sheppard B, Goble D, Pote L, and Noakes TD. Strength and sprint time changes in response to repeated shuttles between the wickets during batting in cricket. J Strength Cond Res 33(11): 3056–3064, 2019—No studies have investigated the impact of repeated sprints between the wickets on lower-limb strength and sprint performance. Therefore, the purpose of this study was to assess changes in knee extensor (EXT) and flexor (FLEX) strength after repeated sprints between the wickets and to relate these to changes in sprint times. Twenty batters completed 2 conditions: one was high-volume running (HVR-twelve sprints per over) and the other, moderate-volume running (MVR-6 sprints per over) between the wickets (42 deliveries in both). Peak isokinetic torque was measured before and after each condition and sprint times were recorded. Eccentric and concentric peak torque decreased significantly (p < 0.05) at 1.05 rad·s−1 for knee EXT in both conditions. There was an 18% (HVR) and 10% (MVR) decline in concentric and eccentric knee EXT peak torque. Peak FLEX torques were significantly (p < 0.05) reduced after HVR (16.7%) but not after the MVR condition (8%). There were similar declines in eccentric FLEX peak torque. Sprint times increased significantly (p < 0.05) during the HVR condition but not in the MVR condition; sprint times in the HVR condition were compromised as early as the third over. We conclude that a high volume of runs significantly reduces muscle function in the lower limbs, partly explaining the impairment in sprint performance. However, because batters slowed as early as the third over in the HVR condition, there may be some form of strategy used in anticipation of a higher overall workload. More middle wicket practices, focusing on repeat shuttle sprints while batting, should be included in the coaching program.

Paillard, T, Kadri, MA, Nouar, MB, and Noé, F. Warm-up optimizes postural control but requires some minutes of recovery. J Strength Cond Res 32(10): 2725–2729, 2018—The aim was to compare monopedal postural control between the dominant leg (D-Leg) and the nondominant leg (ND-Leg) in pre– and post–warm-up conditions. Thirty healthy male sports science students were evaluated before and after a warm-up exercise (12 minutes of pedaling with an incremental effort on a cycle ergometer with a controlled workload). Monopodal postural control was assessed for the D- and ND-Legs before and immediately, 2, 5, 10, and 15 minutes after the warm-up exercise, using a force platform and calculating the displacement velocity of the center of foot pressure on the mediolateral (COPML velocity) and anteroposterior (COPAP velocity) axes. No significant difference was observed between the D-Leg and ND-Leg for both COPML and COPAP velocity in all the periods. In comparison with pre–warm-up, COPML decreased after 15-minute and 10-minute recovery periods for the D-Leg and the ND-Leg, respectively (p < 0.05), whereas COPAP decreased after 10-minute and 15-minute recovery periods (p < 0.001; p < 0.01, respectively) for the D-Leg, and after a 10-minute recovery period for the ND-Leg (p < 0.001). The warm-up optimized monopedal postural control but did not make it possible to distinguish a difference between the D-Leg and the ND-Leg. Some minutes of recovery are required between the end of the whole-body warm-up exercise and the beginning of the postural test to optimize postural control. The optimal duration of recovery turns out to be about 10–15 minutes.

Schaun, GZ, Pinto, SS, Silva, MR, Dolinski, DB, and Alberton, CL. Sixteen weeks of whole-body high-intensity interval training induce similar cardiorespiratory responses compared with traditional high-intensity interval training and moderate-intensity continuous training in healthy men. J Strength Cond Res 32(10): 2730–2742, 2018—Low-volume high-intensity interval training (HIIT) protocols that use the body weight as resistance could be an interesting and inexpensive alternative to traditional ergometer-based high-intensity interval training (HIIT-T) and moderate-intensity continuous training (MICT). Therefore, our aim was to compare the effects of 16 weeks of whole-body HIIT (HIIT-WB), HIIT-T, and MICT on maximal oxygen uptake (V̇o
2max), second ventilatory threshold (VT2), and running economy (RE) outcomes. Fifty-five healthy men (23.7 ± 0.7 years, 1.79 ± 0.01 m, 78.5 ± 1.7 kg) were randomized into 3 training groups (HIIT-T = 17; HIIT-WB = 19; MICT = 19) for 16 weeks (3× per week). The HIIT-T group performed eight 20-second bouts at 130% of the velocity associated to V̇o
2max (vV̇o
2max) interspersed by 10-second passive recovery on a treadmill, whereas HIIT-WB group performed the same protocol but used calisthenics exercises at an all-out intensity instead of treadmill running. Finally, MICT group exercised for 30 minutes at 90–95% of the heart rate (HR) associated to VT2. After the intervention, all groups improved V̇o
2max, vV̇o
2max, time to exhaustion (Tmax), VT2, velocity associated with VT2 (vVT2), and time to reach VT2 (tVT2) significantly (p < 0.05). Moreover, Tmax, vVT2, and tVT2 were greater after HIIT-T compared with HIIT-WB (p < 0.05), whereas oxygen uptake increased and HR decreased during the RE test in all groups (p < 0.05). Our results demonstrate that HIIT-WB can be as effective as traditional HIIT while also being time-efficient compared with MICT to improve health-related outcomes after 16 weeks of training. However, HIIT-T and MICT seem preferable to enhance performance-related outcomes compared with HIIT-WB.

Sanders, GJ, Roll, B, Peacock, CA, and Kollock, RO. Maximum movement workloads and high-intensity workload demands by position in NCAA Division I collegiate football. J Strength Cond Res 34(7): 1974–1981, 2020—The purpose of the study was to quantify the average and maximum (i.e., peak) movement workloads, and the percent of those workloads performed at high intensity by NCAA Division I football athletes during competitive games. Using global positioning system devices (Catapult Sports), low, moderate, and high and total multidirectional movement workloads were quantified by each position. Strategically achieving maximal workloads may improve both conditioning and rehabilitation protocols for athletes as they prepare for competition or return to play after an injury. A total of 40 football athletes were included in the analysis. For the data to be included, athletes were required to participate in ≥75% of the offensive or defensive snaps for any given game. There was a total of 286 data downloads from 13 different games for 8 different football positions. Data were calculated and compared by offensive and defensive position to establish the mean, SD, and maximum workloads during competitive games. The percent high-intensity workload profile was established to assess the total number and percent of high-intensity movement workloads by position. The profile was calculated by dividing a position's maximal high-intensity movement workload by the total (e.g., sum of maximal low, moderate, and high-intensity movements) movement workload. One-way analysis of variances revealed that there was a main effect of football position for total movement workloads and the percent of workloads performed at high intensities (p ≤ 0.025 for all). Maximal high-intensity workloads were 1.6–4.3 times greater than average high-intensity workloads, and the percent of total workloads performed at high intensities varied greatly by position. Strategically training for and using maximal movement workloads can help ensure that athletes are achieving workloads that are similar to the greatest demands of a competitive game.
Pituitary dysfunction and association with fatigue in stroke and other acute brain injury
Authors: Booij H A , Gaykema W D C , Kuijpers K A J , Pouwels M J M , den Hertog H M
Published: May 2018

Background

Poststroke fatigue (PSF) is a highly prevalent and debilitating condition. However, the etiology remains incompletely understood. Literature suggests the co-prevalence of pituitary dysfunction (PD) with stroke, and the question raises whether this could be a contributing factor to the development of PSF. This study reviews the prevalence of PD after stroke and other acquired brain injuries and its association with fatigue.

We performed a bibliographic literature search of MEDLINE and EMBASE databases for English language studies on PD in adult patients with stroke, traumatic brain injury (TBI) or aneurysmatic subarachnoid hemorrhage (aSAH). Forty-two articles were selected for review. Up to 82% of patients were found to have any degree of PD after stroke. Growth hormone deficiency was most commonly found. In aSAH and TBI, prevalences up to 49.3% were reported. However, data differed widely between studies, mostly due to methodological differences including the diagnostic methods used to define PD and the focus on the acute or chronic phase. Data on PD and outcome after stroke, aSAH and TBI are conflicting. No studies were found investigating the association between PD and PSF. Data on the association between PD and fatigue after aSAH and TBI were scarce and conflicting, and fatigue is rarely been investigated as a primary end point.

Key messages

Data according to the prevalence of PD after stroke and other acquired brain injury suggest a high prevalence of PD after these conditions. However, the clinical relevance and especially the association with fatigue need to be established.
Recurrent vertebral fractures in a young adult: a closer look at bone health in type 1 diabetes mellitus
Authors: Thong Eleanor P , Catford Sarah , Fletcher Julie , Wong Phillip , Fuller Peter J , Teede Helena , Milat Frances
Published: May 2018

The association between type 1 diabetes mellitus (T1DM) and bone health has garnered interest over the years. Fracture risk is known to be increased in individuals with T1DM, although bone health assessment is not often performed in the clinical setting. We describe the case of a 21-year-old male with longstanding T1DM with multilevel vertebral fractures on imaging, after presenting with acute back pain without apparent trauma. Dual-energy X-ray absorptiometry (DXA) revealed significantly reduced bone mineral density at the lumbar spine and femoral neck. Extensive investigations for other secondary or genetic causes of osteoporosis were unremarkable, apart from moderate vitamin D deficiency. High-resolution peripheral quantitative computed tomography and bone biospy revealed significant alterations of trabecular bone microarchitecture. It later transpired that the patient had sustained vertebral fractures secondary to unrecognised nocturnal hypoglycaemic seizures. Intravenous zoledronic acid was administered for secondary fracture prevention. Despite anti-resorptive therapy, the patient sustained a new vertebral fracture after experiencing another hypoglycaemic seizure in his sleep. Bone health in T1DM is complex and not well understood. There are significant challenges in the assessment and management of osteoporosis in T1DM, particularly in young adults, where fracture prediction tools have not been validated. Clinicians should be aware of hypoglycaemia as a significant risk factor for fracture in patients with T1DM.

Learning points:

Type 1 diabetes mellitus (T1DM) is a secondary cause of osteoporosis, characterised by reduced bone mass and disturbed bone microarchitecture.

Hypoglycaemic seizures generate sufficient compression forces along the thoracic column and can cause fractures in individuals with compromised bone quality.

Unrecognised hypoglycaemic seizures should be considered in patients with T1DM presenting with fractures without a history of trauma.

Patients with T1DM have increased fracture risk and risk factors should be addressed. Evaluation of bone microarchitecture may provide further insights into mechanisms of fracture in T1DM.

Further research is needed to guide the optimal screening and management of bone health in patients with T1DM.

Giving Students Respect: One of the Great Soft Skills of Teaching and Learning
Authors:   La Trobe University, Melbourne, Australia, Burns E A
Published: May 2018

The importance of soft skills is described for achieving teaching and learning outcomes by educational instructors. The introductory discussion briefly explores the variety of attributes that different scholars classify as soft skills. The emphasis here is on the intangible human qualities that create outstanding learning opportunities, rather than viewings soft skills as simply teaching process in contrast to hard skills of knowledge and performance. Two examples of teaching scholars are considered in elaborating how they achieve high quality learning outcomes: Four principles from Wlodowski and Ginsberg in delivering intensive block courses are outlined. Five principles from Bain’s research into ‘What the Best Teachers Do’ are also described. In each case these teaching exemplars show the importance of soft skills in the craft of teaching. In the last part of the discussion the soft skill of respect is put forward as a fundamentally important, but often undertheorised and underutilised, pedagogical self-discipline and resource for excellent teaching.

Research hypotheses were tested using t-test statistics at 0.05 levels of significance. One of the finding from the study indicates that there is significance difference in the acquisition of Science- Skills between students taught identification of cations using Process–Based instruction and those taught the same concept using lecture method. Based on the research findings, it was recommended among others that periodic workshops, seminars and conferences should be organised for teachers on the selection and implementation of appropriate strategy for teaching chemistry concepts.
Sexual Risk Outcomes of an Emotion Regulation Intervention for At-Risk Early Adolescents
Authors: Houck Christopher D. , Barker David H. , Hadley Wendy , Menefee Maya , Brown Larry K.
Published: May 2018

OBJECTIVE:

With this study, we examined the efficacy of a health intervention program that was focused on emotion regulation (ER) skills in reducing sexual risk behaviors among early adolescents with suspected mental health symptoms.

METHODS:

Seventh grade adolescents with suspected mental health symptoms participated in a 6-week, after-school sexual risk prevention trial in which a counterbalanced, within-school design comparing an ER focused program to a time- and attention-matched comparison group was used. Adolescents completed a computer-based survey regarding their sexual behavior at 6-month intervals for 2.5 years.

RESULTS:

Adolescents who received ER skills training exhibited a delay in the transition to vaginal sex over 30 months compared with those in the comparison condition (adjusted hazard ratio = 0.61; 95% confidence interval [0.42 to 0.89]). They also reported fewer instances of condomless sex over the follow-up period (adjusted rate ratio = 0.36; 95% confidence interval [0.14 to 0.90]). Among those who were sexually active, those in the ER condition reported fewer instances of vaginal or anal sex (adjusted rate ratio = 0.57; 95% confidence interval [0.32 to 0.99]).

CONCLUSIONS:

An intervention used to teach ER skills for the context of health decision-making resulted in lower risk among young adolescents with suspected mental health symptoms by delaying the onset of vaginal sex as well as reducing penetrative acts without a condom. Incorporating emotion education into health education may have important health implications for this age group.
Gentrificación ‘a la caraqueña’: Políticas neoliberales y sus efectos en la ciudad formal-informal
Authors: Herrera Napoleón Carola
Published: May 2018

En Venezuela, entre 1983 y 1999, se identifican cambios en el modelo de desarrollo del país, por la entrada en vigencia de una nueva etapa del modo de producción capitalista, conocida como neoliberal, manifestándose socio-espacialmente en la ciudad. Las políticas neoliberales favorecen la hiperacumulación de capital en manos de unos pocos y privando a las mayorías de sus condiciones vitales. En estas circunstancias, la gentrificación se convierte en una estrategia para extraer -en nombre de la regeneración de la ciudad- la plusvalía del suelo urbano, profundizando las desigualdades socio-espaciales. De ahí que, el objetivo de este artículo es estudiar las causas y particulares efectos de la gentrificación en Caracas a finales del siglo XX. Para ello, el trabajo se estructura en tres partes y una reflexión final: 1.- Hacia un modelo de gestión urbana neoliberal; 2.- La mercantilización del suelo urbano y la estratificación social de la ciudad formal; 3.- El reconocimiento de los barrios y la densificación de la ciudad informal. Finalmente, la gentrificación como práctica urbana acentúa la asimetría socio-espacial entre la ciudad formal e informal.
Funciones discursivas del latín: code-switching en textos de medicina españoles
Authors: Cruz Volio Gabriela
Published: May 2018

En este artículo se exponen los rasgos del code-switching del latín/español en textos de medicina españoles de la Edad Media y de la España renacentista y se exploran los usos de esta mezcla. En primer lugar se revisan los fundamentos para estudiar el code-switching en textos escritos y se alude a la historia de la escritura de textos de medicina en España en lengua vernácula, cuya elección lingüística está determinada por el público al que están dirigidos. En segundo lugar se describen las estructuras del code-switching y se examinan las funciones discursivas del empleo del latín en textos de medicina escritos principalmente en castellano. Se determina que la alternancia con el latín tiene que ver con a) cuestiones terminológicas, b) citación e intertextualidad y c) organización textual del manuscrito. Más allá de esto, la presencia del latín sirve como una práctica de escritura mediante la cual los autores orientan a los destinatarios y se posicionan a sí mismos. A través de las citas, el autor presenta una imagen positiva de médico instruido y construye un juego entre distintas voces que le sirven para exponer sus argumentos y de esta manera validarlos.
El tratamiento del error desde la perspectiva del alumno y su impacto en la enseñanza-aprendizaje de expresión escrita en L2
Authors: Merino Mañueco Susana
Published: May 2018

El tratamiento del error en la enseñanza-aprendizaje de segundas lenguas (L2) ha sido entendido tradicionalmente como la rectificación de ciertas desviaciones de la norma encontradas en las producciones lingüísticas de los alumnos que estudian esa L2. Sin embargo, hoy en día lo entendemos como un concepto amplio que engloba una serie de componentes como son la detección, aceptación, corrección, etc. Los conceptos de error, corrección y feedback (como parte esencial del proceso de corrección de errores) han despertado el interés y la dedicación de profesores, lingüistas y especialistas en Didáctica y, en este sentido, se han llevado a cabo numerosos estudios en torno a estos. En el presente artículo nos adentramos en los procesos relacionados con el tratamiento de errores como son la corrección y la posterior dotación de feedback desde la perspectiva del alumno de L2 focalizando nuestra atención en los conocimientos, la aptitud y la actitud de este hacia el tratamiento de errores en expresión escrita

Published: May 2018

Impending global crises and US demographic changes require the United States to develop its intellectual capital fully, especially in science and engineering, in order to maintain its global leadership and economic strength. As US population demographic changes continue and make their way through our educational system, they will directly affect thinking and practices regarding science and engineering education in the United States, the future of science and engineering professions, and the need for diversity in the science and engineering workforce. It is essential to measure and understand the demographics of science and engineering students who will be available to the workforce in the near future, and their same-gender and same-race role models and mentors.
PROGNOSTIC SIGNIFICANCE OF ENDOTHELIAL DYSFUNCTION MARKERS IN ARTERIAL HYPERTENSION
Authors: Podzolkov V. I. , Bragina A. E. , Bragina N. A.
Published: May 2018

Aim. Assessment of prognostic significance of endothelial dysfunction markers: stable metabolites of nitric oxide (NOx), von Willebrand factor (vWF), endothelin-1 (E1), homocysteine and tissue plasminogen activator (tPA) in essential hypertension (EAH) patients not taking antihypertension therapy systematically.

Material  and  methods. Totally, 12 EAH patients investigated (45 males, 79 females) (mean age 51,4±6,5 y. o., mean duration of AH 7,9±7,3 y.). Concentration of NOx in plasma was measured by spectrophotometry, and of vWF, homocysteine, E1 and tPA — by immune enzyme assay.

Results. By the increase of SCORE risk level, there was significant increase of concentrations of NOx, E1, homocysteine and vWF in EAH patients (p<0,05), there were no changes in tPA levels (p>0,05). In 8 (8±1,1) years after baseline assessment, 115 patients were assessed second time. Of those 13 (11,3%) had cardiovascular events (CVE) and 5 (4,3%) died. By single factorial regression, the rate of CVE in EAH patients relate to homocystein level (р=0,01), NOx (р=0,001) and vWF (р=0,001). By multifactorial analysis, prognostic statistical significance is found for NOx (relative risk (RR) =3,8, р=0,006) and vWF (RR =3,5, р=0,005). In ROC-analysis there were found threshold levels of NOx (>46,6 mcM/L, AUC =0,863) and vWF (>1,68 mg/dL, AUC =0,738), the increase of which is followed by CVE development risk for the levels of NOx >46,6 mcM/L 3,8 times (sensitivity 81,9% and specificity 65,8%), vWF >1,68 mg/dL — 3,5 times (sensitivity 74,3% and specificity 62,7%). Combination of the parameters point on the risk increase up to 6,5 times (р=0,00007).

Conclusion. NOx with the threshold of >46,6 mcM/L (RR =3,8) and vWF >1,68 mg/dL (RR =3,5) do show independent prognostic value for 5-year CVE risk assessment in EAH patients that can be applied as an additional method for risk stratification to estimate a group for more aggressive therapy and CVE prevention.
Vigilantes da moral e dos bons costumes: condições sociais e culturais para a estruturação política da censura durante a ditadura militar
Authors: Setemy Adrianna Cristina Lopes
Published: May 2018

RESUMO Considerando a censura como parte de uma cultura da vigilância à liberdade de expressão, o artigo pretende demonstrar que, além de um eficaz instrumento de violação, quando se trata de defender a moral e os bons costumes, a censura consiste em um instrumento político de legitimação perante setores da sociedade civil, um endosso do Estado àquilo que é considerado pertinente aos valores da família cristã. A discussão será feita a partir da análise das condições sociais e culturais em que se deu o processo de estruturação política e institucionalização da censura de publicações consideradas ofensivas à moral e aos bons costumes durante a ditadura militar. O objetivo do artigo é contribuir com os estudos sobre as estratégias de poder e os comportamentos sociais diante do autoritarismo, a fim de compreender as bases sociais de sustentação do poder autoritário.
Irmãos do Rosário e sectários da religião maometana: sociabilidades entre africanos no Recife oitocentista
Authors: Costa Valéria Gomes
Published: May 2018

RESUMO Este artigo analisa as conexões religiosas entre africanos libertos que transitavam entre a Irmandade do Rosário dos Pretos de Santo Antônio e o culto islâmico no Recife do século XIX. Para os africanos que viveram as experiências de escravidão e de liberdade no Brasil, o pertencimento a mais de uma comunidade religiosa era relevante para assegurar seus arranjos políticos e sociais ou mesmo garantir a manutenção de sua cultura. Este foi o caso de algumas pessoas cujas trajetórias estão vinculadas ao Recife escravista. A proposta dessa discussão é abordar as conexões entre práticas e saberes de religiões africanas em meio ao catolicismo. As principais fontes de pesquisa foram testamentos e inventários post-mortem, jornais e registros paroquiais, que foram analisadas sob as lentes da microanálise italiana.

Background Although intestinal and urinary microbiome perturbations are associated with nephrolithiasis, whether antibiotics are a risk factor for this condition remains unknown.

Methods We determined the association between 12 classes of oral antibiotics and nephrolithiasis in a population-based, case–control study nested within 641 general practices providing electronic health record data for >13 million children and adults from 1994 to 2015 in the United Kingdom. We used incidence density sampling to match 25,981 patients with nephrolithiasis to 259,797 controls by age, sex, and practice at date of diagnosis (index date). Conditional logistic regression models were adjusted for the rate of health care encounters, comorbidities, urinary tract infections, and use of thiazide and loop diuretics, proton-pump inhibitors, and statins.

Results Exposure to any of five different antibiotic classes 3–12 months before index date was associated with nephrolithiasis. The adjusted odds ratio (95% confidence interval) was 2.33 (2.19 to 2.48) for sulfas, 1.88 (1.75 to 2.01) for cephalosporins, 1.67 (1.54 to 1.81) for fluoroquinolones, 1.70 (1.55 to 1.88) for nitrofurantoin/methenamine, and 1.27 (1.18 to 1.36) for broad-spectrum penicillins. In exploratory analyses, the magnitude of associations was greatest for exposure at younger ages (P<0.001) and 3–6 months before index date (P<0.001), with all but broad-spectrum penicillins remaining statistically significant 3–5 years from exposure.

Conclusions Oral antibiotics associated with increased odds of nephrolithiasis, with the greatest odds for recent exposure and exposure at younger age. These results have implications for disease pathogenesis and the rising incidence of nephrolithiasis, particularly among children.

Published: May 2018

This study describes the development and validation of self-regulation learning strategy scale, a 30-item scale that measures pre-teachers’self-regulation learning strategy toward Industry 4.0 & 107 Curriculum Reform. A total of 476 pre-teachers completed the questionnaire. A pilot study (n= 120) was examined factorial validity and reliability of questionnaire and study objects (n= 356) used conﬁrmatory factor analysis. The Self-regulation Learning Strategy Measure (SLSM) has three-factor model (Environmental Orientation, Behavioral Orientation and Process Orientation Self-regulation) was ﬁt using maximum likelihood estimation (MLE). The self-regulation learning strategy scale could be useful for understanding the ways in which teachers think about self-regulation learning issues and could be used to investigate the relationship between other variables. The applications of the SLSM were discussed.

The educational methods continuously should be evaluated. In this research, the views, perceptions and recommendations of undergraduate nursing students on screen-based computer simulation are defined. This was a qualitative research. Two focus group interviews were made. The students said that simulation was beneficial for practice, improved self-confidence, was effective on decision making, and decreased making mistakes. Although the students satisfied the method of this education, the students said that this simulation alone isn’t enough. They said that it should be supported by practice in the skills laboratory to avoid harm to the patient in a real situation.

This research has been designed to compare mothers upbringing methods based on adolescents intelligence groups; high-intelligence, low-intelligence and normal. To this purpose, 194 individuals were chosen from among male and female students of ages 14 and 15 from the city of Ghaenat from southern Khorasan province within the educational year of 2015, by the simple-random method in high-intelligence schools, by the census method in low-intelligence schools and by the multi-stage cluster sampling method in normal schools. The tools employed include the Bamrind questionnaire on upbringing methods. Pierson’s codependence coefficient and multi-variant variance analysis have been used for data analysis.

Results indicated that the difference is significant between intelligence groups regarding tyrannical and logical potency and no significant difference in upbringing methods based on freedom. There is positive and significant difference between mothers of children belonging to high and low-intelligence groups regarding authoritarian and logical potency, and mothers of children belonging to the normal and low-intelligence groups. There’s no significant difference between other intelligence groups and upbringing methods.
