Evaluation of Spin in the Abstracts of Systematic Reviews and Meta-Analyses Focused on the Treatment of Acne Vulgaris: Cross-Sectional Analysis
Authors: Ottwell Ryan , Rogers Taylor C , Anderson J Michael , Johnson Austin , Vassar Matt
Published: January 2020

Background

Spin is the misrepresentation of study findings, which may positively or negatively influence the reader’s interpretation of the results. Little is known regarding the prevalence of spin in abstracts of systematic reviews, specifically systematic reviews pertaining to the management and treatment of acne vulgaris.

Objective

The primary objective of this study was to characterize and determine the frequency of the most severe forms of spin in systematic review abstracts and to evaluate whether various study characteristics were associated with spin.

Methods

Using a cross-sectional study design, we searched PubMed and EMBASE for systematic reviews focusing on the management and treatment of acne vulgaris. Our search returned 316 studies, of which 36 were included in our final sample. To be included, each systematic review must have addressed either pharmacologic or nonpharmacologic treatment of acne vulgaris. These studies were screened, and data were extracted in duplicate by two blinded investigators. We analyzed systematic review abstracts for the nine most severe types of spin.

Results

Spin was present in 31% (11/36) of abstracts. A total of 12 examples of spin were identified in the 11 abstracts containing spin, with one abstract containing two instances of spin. The most common type of spin, selective reporting of or overemphasis on efficacy outcomes or analysis favoring the beneficial effect of the experimental intervention, was identified five times (5/12, 42%). A total of 44% (16/36) of studies did not report a risk of bias assessment. Of the 11 abstracts containing spin, six abstracts (55%) had not reported a risk of bias assessment or performed a risk of bias assessment but did not discuss it. Spin in abstracts was not significantly associated with a specific intervention type, funding source, or journal impact factor.

Conclusions

Spin is present in the abstracts of systematic reviews and meta-analyses covering the treatment of acne vulgaris. This paper raises awareness of spin in abstracts and emphasizes the importance of its recognition, which may lead to fewer incidences of spin in future studies.
Весовые неравенства для потенциала Данкля–Рисса
Authors: Горбачев Дмитрий Викторович , Иванов Валерий Иванович
Published: January 2020

Для классического потенциала Рисса или дробного интеграла $$I_{\alpha}$$ хорошо известны условия Харди-Литлвуда-Соболева-Стейна-Вейса $$(L^p, L^q)$$ -ограниченности со степенными весами. С помощью преобразования Фурье $$\mathcal{F}$$ потенциал Рисса определяется равенством $$\mathcal{F}(I_{\alpha}f)(y)=|y|^{-\alpha}\mathcal{F}(f)(y)$$. Важным обобщением преобразования Фурье стало преобразование Данкля $$\mathcal{F}_k$$, действующее в лебеговых пространствах с весом Данкля, определяемым с помощью системы корней $$R\subset\mathbb{R}^d$$, ее группы отражений G и неотрицательной функции кратности k на R, инвариантной относительно G. С. Тангавелу и Ю. Шу с помощью равенства $$\mathcal{F}_k(I_{\alpha}f)(y)=|y|^{-\alpha}\mathcal{F}_k(f)(y)$$ определили D-потенциал Рисса. Для D-потенциала Рисса также были доказаны условия ограниченности в лебеговых пространствах с весом Данкля и степенными весами, аналогичные условиям для потенциала Рисса. На конференции "Follow-up Approximation Theory and Function Spaces" в Centre de Recerca Matem`atica (CRM, Barcelona, 2017)  М.Л. Гольдман поставил вопрос об условиях $$(L_p,L_q)$$-ограниченности D-потенциала Рисса с кусочно-степенными весами. Рассмотрение кусочно-степенных весов позволяет выявить влияние на ограниченность D-потенциала Рисса поведения весов в нуле и бесконечности. В настоящей работе на этот вопрос дается полный ответ. В частности,в случае потенциала Рисса получены необходимые и достаточные условия. В качестве вспомогательных результатов доказаны необходимые и достаточные условия ограниченности операторов Харди и Беллмана в лебеговых пространствах с весом Данкля и кусочно-степенными весами.

ESTRATÉGIAS DE CONTROLE DAS CLASSES PERIGOSAS: O ENSINO PROFISSIONAL DO IMPÉRIO À REPÚBLICA
Authors: Afonso José António Martin Moreno , Santos Renato Marinho Brandão
Published: January 2020

O artigo analisa as diferentes concepções politico-educativas sobre o ensino profissional no Brasil, desde os Liceus e Casas de Educandos, no período imperial, até as Escolas de Aprendizes, estabelecidas nas capitais brasileiras a partir de 1910, durante a Primeira República. Discute, ao longo dos diferentes períodos, a associação entre o ensino profissional e o controle das denominadas “classes perigosas”. Especificamente em relação à República, observa o diálogo entre esse regime, que procura se associar às ideias do novo e do progresso, e as Escolas enquanto instituições modernas responsáveis por estabelecer padrões de comportamento e valores. Em conclusão, afirma que os caminhos para consolidação do ensino profissional no Brasil foram tortuosos, tendo como reflexo, entre outros pontos, os altos índices de evasão verificados nas Escolas de Aprendizes.

A QUEM SERVE A “NEUTRALIDADE”? ANÁLISE DO MOVIMENTO ESCOLA SEM PARTIDO À LUZ DA IDEOLOGIA GERENCIALISTA
Authors: Gemelli Catia Eli
Published: January 2020

Desde 2014, diversos Projetos de Lei foram apresentados nos poderes legislativos brasileiros, sob a alcunha de combate à “doutrinação ideológica nas instituições de ensino”, em um movimento que se autodenomina como “Escola sem Partido” (ESP). A partir da compreensão de que o ESP possui determinações mais profundas e menos visíveis, este artigo propôs-se a examinar o movimento com base em suas interlocuções com a profusão da ideologia gerencialista nos espaços educacionais e a retomada do discurso de defesa de uma educação tecnicista.
Effect of Artificial Aging Temperature on Mechanical Properties of 6061 Aluminum Alloy
Authors: Kumar Mukesh , Baloch Muhammad Moazam , Abro Muhammad Ishaque , Memon Sikandar Ali , Chandio Ali Dad
Published: January 2020

Aluminum alloys have been attracted by several engineering sectors due to their excellent strengthweight ratio and corrosion resistant properties. These are categorized into 1, 2, 3, 4, 5, 6, 7and 8xxx on the basis of alloying elements. Among these 6xxx series contains aluminum–magnesium–silicon as alloying elements and are widely used in extruded products and automotive body panels. The major advantages of these alloys are good corrosion resistance, medium strength, low cost, age hardening response no yield point phenomenon and Ludering. 6xxx series alloys generally have lower formability than other aluminum alloys which restrict their utilization for wide applications. Keeping in view of the shortcomings in the set of mechanical properties of 6xxx series the efforts were made to improve the tensile strength and toughness properties through age hardening. In present study heat treatment cycles were studied for 6061 aluminum alloy. Three different age hardening temperatures 160, 200 and 240oC were selected. The obtained results showed that 17.26, 7.69, and 10.51% improvement in tensile strength, toughness and hardness respectively was achieved with solution treatment at 380oC followed by an aging 240oC. Microstructural study revealed that substantial improvements in the mechanical properties of 6061 aluminum alloy under heat treatment were achieved due to precipitation of Mg2Si secondary phase.

Published: January 2020

Single phase MgAl2O4 was made from a one-to-one molar ratio of MgO and Al2O3
powders mixed using ball-milling. Mixtures of MgO and Al2O3 were
subsequently treated in planetary ball mill for 30, 60, 90 and 120 minutes
in air. The aim of this study was to examine phase composition,
microstructure, and densification behavior of sintered specimens. After
sintering in dilatometer at 1500?C, the powder was converted to single
phase MgAl2O4. The results show that mechanical activation improved the
densification behavior of MgAl2O4 sintered specimens, and it reduced the
onset temperature for sintering by approx. 100?C. Based on dilatometer
data, powders were subsequently densified at 1450?C by hot pressing. Almost
?ll specimens exhibited full density, while sample activated for 30 minutes
showed the fastest densification rate.
Towards a high strength ductile Ni/Ni3Al/Ni multilayer composite using spark plasma sintering
Authors: Mardiha P. , Bahrami A. , Mohammadnejad A.
Published: January 2020

This paper is an attempt to develop an innovative high strength and ductile
Ni/Ni3Al/Ni multilayer composite, using spark plasma sintering (SPS). Ni3Al
powders were first synthesized by mechanical alloying of elemental pure Ni
and Al powders. The synthesized intermetallic powders were then mixed with
Ni powders in a way that a Ni/Ni3Al/Ni multilayer composite can be achieved.
Scanning electron microscope, optical microscope, energy dispersive X-ray
spectroscopy (EDS), microhardness, and shear punch tests were used to
characterize microstructure and mechanical properties of the synthesized
composite. Results show that a rather sharp interface with a perfect
metallurgical bonding has formed at the Ni/Ni3Al joint. The synthesized
multilayer composite has a perfect combination of strength and ductility.
The maximum shear strength of Ni/Ni3Al/Ni multi-layer composite is
significantly higher than that of Ni3Al, while its ductility is comparable
to that of pure Ni.
The mechanisms of cavitation erosion of raw and sintered basalt
Authors: Pavlovic Marko , Dojcinovic Marina , Prokic-Cvetkovic Radica , Andric Ljubisa
Published: January 2020

The paper analyzes the morphology of cavitation damage of raw and sintered
basalt samples. The experiment was conducted using the ultrasonic vibratory
cavitation test method according to the ASTM G-32 standard. During the
determination of the resistance to the effect of cavitation, a change in the
mass of samples was observed in the function of the cavitation time of
operation. The morphology of damage caused by the effect of cavitation was
followed by scanning with an electron microscope, and the level of
degradation of the surface of the samples was quantified using the image
analysis. The results showed a significantly higher degree of resistance of
sintered basalt, with a cavitation rate of 0.019 mg/min relative to raw
basalt, with a cavitation rate of 0.738 mg/min. After 120 minutes of
exposure to the cavitation effect, a smaller number of small pits on the
surface of sintered basalt were observed, while a higher level of damage to
the surface with the appearance of numerous pits was found in raw basalt,
which can be connected in some places to larger and deeper pits in some
places. The obtained results indicate the possibility of using sintered
basalt for the production of parts that will be exposed to the effects of
high cavitation loads.
Hammering the past: The experimental (re)construction and usage of prehistoric mining hammerstones from the Prljusa-Mali Sturac site, Rudnik Mountain
Authors: Dimic Vidan
Published: January 2020

The locality of Prljusa-Mali Sturac on Rudnik Mountain is one of the richest
prehistoric mining sites in Europe, taking into account the number of
recorded, collected and analysed mining hammerstones. The reasonably
estimated number of these tools of 2,000 and more clearly depicts the
intensity of prehistoric mining activities at this locality as well as the
conspicuousness of the mining potential which this mountain possessed.
During the archaeological research conducted so far, 688 hammerstones have
been collected and analysed (of which 478 are from recent excavation
campaigns), thus producing results based on which hypotheses were made
regarding their manufacture and use. Consequently, in the summer of 2017, an
experimental (re)construction was undertaken on three basic types of these
tools, as a complementary segment to a set of functional and typological
analyses. The goal of the experimental research was to enable and gather as
much as possible data that would serve as a comparative filter for testing
previously set hypotheses and research questions related to the manufacture
and usage modes of this category of mining tools. The mining hammerstones
made for the purpose of this experiment proved to be extensively efficient
in practice. The obtained results enabled a more complete understanding of
the prehistoric mining technology on this site, but also raised some new
questions.
Archaeological site of Bolnica in Paracin and its importance for the prehistory of the Central Morava Region: A contribution in chronology and horizontal and vertical stratigraphy
Authors: Filipovic Vojislav , Mladenovic Ognjen , Vuckovic Vesna
Published: January 2020

The paper presents the horizontal and vertical stratigraphy of the site of
Bolnica in Paracin, based on both earlier and the latest archaeological
excavations and the material which had been collected for decades by the
Hometown Museum in Paracin, as a result of the construction works connected
with the constant urbanisation of the area. The presented archaeological
material is attributed to a period from the Early Neolithic to the so-called
Dacian La T?ne, meaning the 2nd century AD. One of the subjects discussed in
this paper is the possibility that the sites of Bolnica and Motel Slatina,
in fact, represent one large site, which was artificially divided by the E
75 highway and the Serbian Glass Factory. The comparative analysis, which
encompassed the sites positioned on the right bank of the Velika Morava
River, showed that this is one of the sites with the most independent
chronological sequences in the Central Morava Region. Likewise, the
importance of this site as a strategic point and an important intersection
on the route from the Danube River to the Central Balkans, and further
towards the south and east is underlined. Finally, we analysed the
appearance of Dacian material culture during the 1st and the 2nd century AD
and compared the occurrence of certain forms and decorations with relevant
sites in present-day Romania. The paper cautiously suggests that the Dacian
material culture represents traces of the deportation of 100,000
Transdanubians to the territory of Moesia by the legate Silvanus Aelianus,
possibly between 61 AD and 64 AD, during the reign of Emperor Nero, which
has been partially confirmed by new archaeological excavations at the site
of Glozdak-Lidl during 2018.
The moulds from Velebit and European bronze age metal anvils

Published: January 2020

During the first excavations of the cemetery dating from the Bronze Age and
Early Antiquity in the village of Velebit near Kanjiza (Northern Serbia) one
of the excavated artefacts was found to belong to a used and broken stone
mould for casting anvils. However, without an expert archaeologist to
supervise the recovery of this find, which remained unknown for decades
after its discovery, as a starting point, the authors of this article
present a synthesis that takes into account several aspects of this
significant class of metalcraft object. This proceeds from the history of
the excavation to the general role of European Bronze Age anvils in gold and
bronze metalworking, and then further on to their typological,
terminological, chronological and functional analysis and to their
long-range distribution as a sign of an interregional network of craftsmen,
including their social context and symbolism.
A case of myositis ossificans traumatica on one skeleton from Viminacium
Authors: Vulovic Dragana , Miladinovic-Radmilovic Natasa , Mikic Ilija
Published: January 2020

The Roman city and military camp of Viminacium is situated between the
villages of Stari Kostolac and Drmno, 12 kilometres north-east of Pozarevac,
close to the confluence of the Mlava and the Danube. During its history, it
became the biggest urban settlement and the capital of the province of Upper
Moesia (Moesia Superior), later First Moesia (Moesia Prima). In one of the
necropoles of Viminacium, Pecine, in grave No. 5785, skeletal remains of a
juvenile male individual were discovered. The burial took place in Late
Antiquity. Anthropological analyses revealed a fracture of the right femur
followed by myositis ossificans traumatica. The trauma to the bone can damage
the overlying muscle and, occasionally, the muscle tissue will respond to the
trauma by producing bone directly in the muscle tissue itself. This condition
is known as myositis ossificans traumafica (post-traumatic myositis
ossificans or myositis ossificans circumscripta) and is most likely to occur
in response to trauma in young male individuals, and in the femoral (the
quadriceps muscles) or humeral region (brachium muscles).
Burial of a woman with an amber distaff at Viminacium
Authors: Dankovic Ilija
Published: January 2020

A luxurious set of spinning implements was discovered as part of the
furnishings in the grave of a woman, unearthed in the surroundings of
ancient Viminacium. A unique amber distaff with the upper part modelled in
the form of a female bust stands out as the most important part of the grave
assemblage. Similar artefacts were often misinterpreted, but this specimen
was found together with a spindle, thus confirming that it actually is a
distaff. Miniature copies of spinning equipment made out of precious
materials are known from sepulchral contexts, and are described as objects
expressing feminine virtue. It is considered that they were used in wedding
rites, thus indicating the possible age of the deceased. Spinning implements
can represent useful tools for studying the life course of Roman women. In
this paper, an attempt was made to identify the divinity or person depicted
on the distaff from Viminacium, considering the symbolic nature of these
artefacts.
Young foreign women in prison: A case study in Malaga prison

Published: January 2020

The aim of this paper is to present the results of the research on the
reality that young migrant women face in prison, trying to analyze whether
they, judging by their own speech, consider themselves victims of some sorts
of discrimination in Malaga?s prison. The main objective is to get to know
the previous history of women before entry to prison, their criminal
experience, experience in the judicial process and their daily activities in
the penitentiary centre, as well as the treatment received by the prison
staff. In addition, the paper tries to explain the expectations for the
future of these young women after their release. The final conclusions
reflect a very complicated situation for women living in Malaga prison,
especially when factors such as age and migration are also involved.
Invisible victims of non-ethical reporting on suicide in Serbia
Authors: Dokmanovic Mirjana
Published: January 2020

The subject of this paper is the analysis of the way the daily printing in
Serbia is engaged in the reporting on suicide and the level of respect of
the Code of Ethics of Serbian Journalists. The aim of thee paper is to
present and analyse the findings of the research on the manner of reporting
on cases of suicide in electronic editions of eight daily newspapers in the
period from 1st January to 30th September 2018. Both quantitative and
qualitative analysis of the media content, including photographs and video
footage was performed. The research findings showed that only two dailies
out of eight fully followed the professional and ethical conduct for
journalists. In total, 223 articles have been published about cases of
suicide. Out of this number, the Code of Ethics has been violated in 147
articles (65.9%). In 40 articles media un-ethically reported on cases of
suicide of children and minors. The most frequent methods of the Code of
Ethics? violations include: disrespect of dignity, privacy and grief of
people who have experienced the death from suicide of a loved one,
publishing photographs of the scene of a given suicide, and pictures of an
individual who has died by suicide and of his/her family members, and using
language which sensationalises suicide. Due to unethical reporting, members
of the family of the persons who committed suicide have been exposed to
additional trauma and stigmatization, thus becoming invisible victims of
irresponsible media reporting. The analysis of the legal and institutional
framework has shown that mechanisms for the protection of their right to
privacy and dignity are in place. Beside court protection, the victims of
non-ethical reporting may seek protection from the Press Council, an
independent self-regulatory body that has been established for monitoring
the observance of the Code of Ethics and solving complaints made by
individuals and institutions related to media content. However, it has been
found that the traumatised and stigmatised family members very rarely use
these opportunities provided. The analysis of the complaint proceedings
before the Press Complaints Commission from the beginning of its work in
September 2011 to 2019 showed that only three persons filed complaints
against media seeking protection of their right to privacy and dignity.
Women in the police profession and a review of the situation in the Serbian police
Authors: Tomic Marta
Published: January 2020

The aim of the paper is to present the results of the research in which we
examined the professional integration and advancement of women employed in
the Police Directorate for the City of Belgrade. The problem of integration
and advancement of women in the Serbian police was investigated at the
Police Directorate of the City of Belgrade, Ministry of Internal Affairs of
the Republic of Serbia, in the period from 2016 to 2017, by using a
qualitative and quantitative methodology. The results showed that there are
objective circumstances that stop women at a certain stage of career
promotion, which have origins and a multi-level stronghold, emphasized at
the social level influenced by patriarchal relationships. The results
suggest that circumstances of a formal and informal nature are aggravating
and that they fundamentally confirm theories of gender inequality in the
masculine professions, such as the police profession. In police services, in
Serbia, women still constitute a minority that is covertly discriminated
against and publicly segregated on the sidelines of the profession.
Sexual harassment from anti-discriminatory to criminal law regulation with reference to the key reasons for the invisibility of the victims
Authors: Paunovic Nikola
Published: January 2020

Ratification of the Council of Europe Convention on preventing and combating
violence against women and domestic violence adopted in 2011 creates an
obligation for the Party States to take the necessary legislative or other
measures to ensure that sexual harassment is subject to criminal or other
legal sanctions. Bearing in mind that sexual harassment, even before the
adoption of this Convention, was prescribed by the anti- discriminatory and
labour laws of the Party States, the paper focuses on the analysis of
normative regulation of sexual harassment in the criminal legislation of the
Republic of Serbia as well as in the comparative legal solutions, with the
purpose of discussing the most important controversial issues concerning
this new incrimination, giving particular attention to considering key
reasons of objective and subjective nature that affect the invisibility of
the victims of this criminal offence. Recognizing deficiencies of the
criminal law regulation of sexual harassment, above all the widespread zone
of punishability, de lege ferenda proposal for a normative reformulation of
the essential elements of this criminal offence is provided in the
concluding considerations, with the purpose of improving its application in
practice.
Numerical analysis of semiconductor thermoelectric generator
Authors: Wu Zhifei , Xiang Yuxia , Wang Jianjun
Published: January 2020

A thermoelectric generation model is proposed based on the structure of thermoelectric generator, working conditions, the effect of air heat transfer and contact resistance in thermoelectric components. In addition, the effect of the thermoelectric generator output performance under the condition of different temperature of the cold and heat source, contact resistance between the cold-end and hot-end, the load resistance and the contact resistance is calculated. The results show that the output voltage is linear associate with the temperature difference between hot and cold ends, however, the output power increase along with the increase of temperature of hot-end and decrease of cold-end. The output voltage reaches 5.76 V and the output power reaches 9.81 W when the temperature difference is 200?C. Assume that the contact resistance is ignored, the output voltage and power reach peak values of 3.61 V and 3.85 W. The output performance of thermoelectric generator decreases with the increase of thermal contact resistance at hot and cold ends, and the reduction is getting lower and lower. With the increase of the load resistance, the output power increases at the beginning and then decreases. The optimal output power is 3.69 W when the contact resistance is 0 ? and the optimal load resistance is 3.3 ?. The maximum output power corresponding to neglecting the contact resistance will be reduced by 13.5% when the contact resistance is 0.5 ?.

Experimental investigation of flow and heat transfer characteristics on matrix ribbed channel
Authors: Zhang Bo , Hong Quan , Dou Yuanyuan , Ji Honghu , Chen Rui
Published: January 2020

The effect of the rib width to height ratio t/e and width to pitch ratio t/p on the local heat transfer distribution in a rectangular matrix ribbed channel with two opposite in line 45? ribs are experimentally investigated for Reynolds numbers from 54000 to 150000. The rib height to channel height ratio e/H is 0.5, t/p and t/e both varies in range of 0.3-0.5. To simulate the actually situation in turbine blades, and provide useful direct results for turbine blade designers, the parameters are same with the blade. The experiments results show that, in comparison to fully developed flow in a smooth pipe of equivalent hydraulic diameter, the Nusselt number inside the matrix-ribbed rectangular channel is increased up to 5 to 9 times higher, while total pressure drop is enlarged by up to significant magnitude. The Nusselt number ratio increases with t/p and t/e increased. Semi-empirical heat transfer is developed for designing of cooling channel.
Optimal design of nozzle for filter bag cleaning device of combined air-conditioning based on fluid mechanics
Authors: Huang Dongping , Zhuang Yingke , Lin Shaojie
Published: January 2020

Nozzles are terminal accessories and important parts of equipment for spraying high speed water flow. The shape of nozzle is the main reason that affects the change of pressure and velocity field. For this reason, this paper uses ANSYS software to monitor the pressure and velocity distribution of the internal flow field of nozzle and the high-speed flow field outside the nozzle. In the paper are compared and analyzed the flow field changes due to different nozzle shapes and the influences of various parameters on the nozzle flow field, providing a reference for the rational use of the structural parameters of nozzle.
Self-compensation method for error of positioning accuracy of intelligent synchronous manipulator
Authors: Wang Minchuan
Published: January 2020

The traditional positioning method of manipulator has the problems of poor accuracy and low efficiency. According to the positioning task type of the manipulator, the positioning model of the manipulator is constructed. Set up the manipulator joint co-ordinate system, combined with kinematics analysis, through the link parameters and joint variables to achieve the positioning analysis of the manipulator. The inverse method is introduced to compensate the positioning error of the robot arm by using image feature extraction and recognition technology. The experimental results show that the average positioning error of the traditional method is 1.4 mm, while the average positioning error of the proposed method is only 0.2 mm. The performance of the proposed method is proved to be better.

Current therapeutic strategies for diabetic foot ulcer (DFU) have focused on developing topical healing agents, but few agents have controlled prospective data to support their effectiveness in promoting wound healing. We tested a stem cell mobilizing therapy for DFU using a combination of AMD3100 and low-dose FK506 (tacrolimus) (AF) in streptozocin-induced type 1 diabetic (T1DM) rats and type 2 diabetic Goto-Kakizaki (GK) rats that had developed peripheral artery disease and neuropathy. Here, we show that the time for healing back wounds in T1DM rats was reduced from 27 to 19 days, and the foot wound healing time was reduced from 25 to 20 days by treatment with AF (subcutaneously, every other day). Similarly, in GK rats treated with AF, the healing time on back wounds was reduced from 26 to 21 days. Further, this shortened healing time was accompanied by reduced scar and by regeneration of hair follicles. We found that AF therapy mobilized and recruited bone marrow–derived CD133+ and CD34+ endothelial progenitor cells and Ym1/2+ M2 macrophages into the wound sites, associated with enhanced capillary and hair follicle neogenesis. Moreover, AF therapy improved microcirculation in diabetic and neuropathic feet in GK rats. This study provides a novel systemic therapy for healing DFU.

A single bout of exercise enhances insulin action in the exercised muscle. However, not all human studies find that this translates into increased whole-body insulin action, suggesting that insulin action in rested muscle or other organs may be decreased by exercise. To investigate this, eight healthy men underwent a euglycemic-hyperinsulinemic clamp on 2 separate days: one day with prior one-legged knee-extensor exercise to local exhaustion (∼2.5 h) and another day without exercise. Whole-body glucose disposal was ∼18% lower on the exercise day as compared with the resting day due to decreased (∼37%) insulin-stimulated glucose uptake in the nonexercised muscle. Insulin signaling at the level of Akt2 was impaired in the nonexercised muscle on the exercise day, suggesting that decreased insulin action in nonexercised muscle may reduce GLUT4 translocation in response to insulin. Thus, the effect of a single bout of exercise on whole-body insulin action depends on the balance between local effects increasing and systemic effects decreasing insulin action. Physiologically, this mechanism may serve to direct glucose into the muscles in need of glycogen replenishment. For insulin-treated patients, this complex relationship may explain the difficulties in predicting the adequate insulin dose for maintaining glucose homeostasis following physical activity.
Racial Ethnic Disparities in Youth With Type 1 Diabetes Participating in Diabetes Summer Camps

Published: January 2020

OBJECTIVE

Diabetes camps are beneficial for campers and include benefits such as increases in diabetes knowledge, glycemic control, and psychological functioning. Racial/ethnic minority youth are likely to have poorer disease management and glycemic control. We hypothesized that minority youth with type 1 diabetes have reduced participation in diabetes summer camps.

RESEARCH DESIGN AND METHODS

We analyzed deidentified data from 5,256 campers with type 1 diabetes who participated in a network of 48 American Diabetes Association–affiliated summer camps in 2018, and we compared participation rates by racial/ethnic category to the most recent SEARCH for Diabetes in Youth study prevalence rates.

RESULTS

Camper demographics were significantly different than in the general population of children with type 1 diabetes (P < 0.001). Minority youth were more likely to attend day camp, be first-time campers, and request financial aid, and they were less likely to be on insulin pump therapy or use continuous glucose monitors.

CONCLUSIONS

Racial/ethnic minority youth with diabetes are underrepresented in diabetes camps nationwide.

Published: January 2020

OBJECTIVE

To assess the contemporaneous prevalence of diabetic peripheral neuropathy (DPN) in people with type 1 diabetes (T1D) in Scotland and study its cross-sectional association with risk factors and other diabetic complications.

RESEARCH DESIGN AND METHODS

We analyzed data from a large representative sample of adults with T1D (N = 5,558). We assessed the presence of symptomatic neuropathy using the dichotomized (≥4) Michigan Neuropathy Screening Instrument Patient Questionnaire score. Logistic regression models were used to investigate associations between DPN and risk factors, as well as with other complications.

RESULTS

The burden of DPN is substantial with 13% prevalence overall. Adjusting for attained age, diabetes duration, and sex, the odds of DPN increased mainly with waist-to-hip ratio, lipids, poor glycemic control (odds ratio 1.51 [95% CI 1.21–1.89] for levels of 75 vs. 53 mmol/mol), ever versus never smoking (1.67 [1.37–2.03]), and worse renal function (1.96 [1.03–3.74] for estimated glomerular filtration rate levels <30 vs. ≥90 mL/min/1.73 m2). The odds significantly decreased with higher HDL cholesterol (0.77 [0.66–0.89] per mmol/L). Living in more deprived areas was associated with DPN (2.17 [1.78–2.65]) for more versus less deprived areas adjusted for other risk factors. Finally, individuals with prevalent DPN were much more likely than others to have other diabetes complications.

CONCLUSIONS

Diabetic neuropathy remains substantial, particularly affecting those in the most socioeconomically deprived groups. Those with clinically manifest neuropathy also have a higher burden of other complications and elevated levels of modifiable risk factors. These data suggest that there is considerable scope to reduce neuropathy rates and narrow the socioeconomic differential by better risk factor control.
O papel do discurso religioso na construção da identidade etnocultural dos imigrantes italianos em Curitiba no final do século XIX
Authors: Machioski Fábio Luiz , Gonçalves Marcos
Published: January 2020

No presente artigo, pretendemos discutir como, e por que, a religião conseguiu influenciar no processo de construção da identidade etnocultural dos imigrantes italianos que se instalaram na região de Curitiba no final do século XIX. Almejamos entender de que modo o discurso religioso foi útil para o forjar de um sentimento de pertencimento étnico entre os indivíduos desse grupo  específico de estrangeiros que se fixou no entorno da capital paranaense. Com o intuito de encontrar respostas para esta questão, apresentamos algumas definições e ideias sobre religião e identidade elaboradas pelos sociólogos Peter Berger, Pierre Bourdieu e Denys Cuche, como também pelo filósofo Paul Valadier. Tais conceitos, como por exemplo o de poder simbólico e de habitus religioso, serviram para analisar o discurso do padre Pietro Colbacchini, sacerdote católico que organizou a prática religiosa dos imigrantes italianos em Curitiba, e assim compreender a relevância que a religião assumiu junto ao referido processo de identificação sociocultural.
Gênero e neopentecostalismo: um olhar a partir do projeto Godllywood
Authors: Oliveira Alesca Prado de , Enoque Alessandro Gomes
Published: January 2020

É objeto do presente estudo desvelar a dinâmica das relações que são construídas a partir do sagrado para com o gênero e, para tanto, adentraremos no universo da Igreja Universal do Reino de Deus (IURD), através de seu projeto para as mulheres fiéis, denominado Godllywood. Por meio de pesquisa teórica sobre a produção científica que aborda a inter-relação gênero e religião, e de pesquisa documental no canal virtual do projeto, coletamos informações sobre os desafios lançados pela líder iurdiana às suas leitoras. A dicotomia estabelecida entre o tradicionalismo evangélico e a aceitação dos novos valores da sociedade se exemplifica no projeto apresentado.
A fé dos jornalistas e as práticas religiosas no Brasil
Authors: Mick Jacques , Furtado Kevin Willian Kossar
Published: January 2020

O artigo compara os dados disponíveis sobre as religiões dos jornalistas brasileiros com as características gerais da religiosidade da população a partir dos dados presentes no Perfil do jornalista brasileiro, de 2012, e no censo de 2010 do Instituto Brasileiro de Geografia e Estatística (IBGE). O objetivo é compreender se as particularidades da experiência religiosa entre os jornalistas podem ter efeitos na cobertura do tema, algo que é relevante diante das consequências sociopolíticas e econômicas das mudanças recentes na religiosidade no país. Os dados indicam três diferenças marcantes entre os jornalistas: a) presença mais significativa de não praticantes e ateus; b) participação significativamente menor de católicos e evangélicos; e c) maior expressividade de espíritas e praticantes de religiões de origem africana. O texto suscita a hipótese de que essas diferenças, junto a outros fatores, podem explicar fenômenos como a relativa desatenção da cobertura jornalística ao crescimento da população neopentecostal no país e as abordagens em geral positivas que o espiritismo recebia da mídia.
PUEBLA: DA OPÇÃO PELOS POBRES A UMA IGREJA EM SAÍDA
Authors: Peretti Clélia , Nascimento Jeverson
Published: January 2020

Este artigo disserta sobre os principais temas enfatizados no documento conclusivo da III Conferência latino-americana, realizada em Puebla de los Angeles, no México, do dia 27 de janeiro a 13 de fevereiro de 1979. Discorre sobre experiência eclesial, as opções de Puebla, os rumos da Evangelização no Continente latino-americano, cujo principal foco é a libertação e a promoção da dignidade dos pobres. Mostra, por meio da análise do Documento de Puebla, a continuidade do uso do método teológico-pastoral do ver, julgar e agir, na leitura da realidade socioeconômica, política e cultural, assim como as chaves de leitura para a intepretação do Documento: evangelização no presente e no futuro, comunhão e participação, as linhas e as orientações pastorais para a inclusão dos diferentes rostos dos pobres. O artigo retrata a importância da vocação, dos carismas e da atuação dos leigos na Igreja e no mundo. A memória dos 40 anos de Puebla, de modo particular o clamor dos pobres, remete à exortação apostólica Evangelii Gaudium, do Papa Francisco, com ênfase na Igreja em Saída, voltada para o fortalecimento da causa libertadora dos pobres, da solidariedade com o ser humano, do reconhecimento da dignidade humana e direitos humanos e civis. Enfatiza que a evangelização da cultura, característica da Igreja Missionária sob o dinamismo do Espírito, é o ponto de conexão com a Igreja em Saída proposta pelo Papa Francisco. A Igreja em Saída é a comunidade de discípulos missionários que “primeireiam”, que se envolvem, que acompanham, que frutificam e festejam.
LUTERO E O SACERDÓCIO UNIVERSAL DO CRENTE
Authors: Lanfranchi Marcelo Amaral
Published: January 2020

Este estudo retrata a evolução do pensamento de Lutero que o levou a conceber o conceito do sacerdócio universal do crente, interpretado pela Igreja Católica Apostólica Romana como uma afronta à hierarquia clerical já estabelecida e consolidada, já que se opunha à autoridade papal e menosprezava a hierarquia e o sacerdócio ministerial. Nesse artigo, abordo o contexto histórico e social da Europa e da Alemanha de Lutero, bem como da Igreja Católica de então. Pretendo mostrar que o pensamento de Lutero não veio apenas de um descontentamento com um comportamento que ele atribuiu, exageradamente, a todo o clero e ao próprio Papa, mas a uma situação mais complexa, que envolvia aspectos sociais e econômicos que já estavam mudando toda a estrutura social da Europa e, principalmente, da Alemanha há séculos. Aspectos teológicos bem fundamentados acerca do purgatório e das indulgências, divulgados e utilizados com finalidade econômica por alguns membros do clero e da nobreza, fizeram com que Lutero se sentisse compelido a desenvolver uma teologia que contrastasse com a aceita pela Igreja. O artigo procura buscar as raízes do pensamento de Lutero que o fizeram questionar a hierarquia eclesiástica.
Fronteiras eclesiais no pontificado de Francisco
Authors: Wolff Elias , Colet Raquel De Fátima
Published: January 2020

Para bem compreender o pontificado de Francisco, é preciso analisar os percursos fronteiriços pelos quais ele transita. O objetivo deste artigo é mostrar o papa Francisco como um homem de fronteiras, que as reconhece em seu valor eclesial, mas também em muito as amplia ou supera. O método utilizado é o da análise qualitativa da bibliografia que mostra o posicionamento do papa nas questões de fronteiras na igreja. O resultado é a apresentação de um diagnóstico das atuais fronteiras doutrinais e estruturais do catolicismo e suas implicações para uma igreja em “estado permanente de missão”. Mostra como o papa Francisco faz o discernimento das fronteiras que se justificam evangelicamente na igreja e aponta para a superação daquelas que não se legitimam na proposta de uma “igreja em saída”, por um processo de reformas como permanente conversão pastoral.
Apontamentos sobre cristologia joanina: pressupostos epistemológicos da saga cristológica do herói do Quarto Evangelho
Authors: Guerra Danilo Dourado
Published: January 2020

O presente artigo tem em sua gênese uma tentativa de contribuição epistemológica em relação aos meandros que envolvem o complexo processo de construção e estruturação cristológica no Quarto Evangelho. Nesse intuito, objetivamos fornecer alguns substratos teóricos interpretativos para um ensaio de decodificação da enigmática face do Jesus joanino. O primeiro substrato teórico a ser apontado diz respeito ao âmbito dialógico entre a cristologia joanina e o restante do arcabouço cristológico neotestamentário. A segunda camada teórico-interpretativa abordada alude aos vetores interpretativos circunstanciais da vida da comunidade joanina, que corroboram ou influenciam na construção da imagem do herói do Quarto Evangelho.
