Published: July 2017

Powder metallurgy has grown with the expansion of various industry. Automotive industry had the most strong influence. Today, more than 90% of PM products are used in the transportation industry. Development of new materials such as magnetic materials is expected to meet the new trends of automotive industry, electric and hybrid vehicles.

Soft magnetic composites (SMC) are PM materials based on ferromagnetic powder particles covered by electric insulation layer. Concept of SMC’s and PM technologies offer possibility to become faster, use higher frequencies, become smaller and denser, save more energy, achieving high permeability and lower core loss in high frequency region, which is required for soft magnetic materials. Investigation of correlations among compaction parameters, inner structure, magnetic and mechanical properties are presented.
Combining morphology, scanning electron microscopy, and molecular phylogeny to evaluate the taxonomic power of scales in genusAphaniusNardo, 1827 (Teleostei: Cyprinodontidae)
Authors: Teimori Azad , Motamedi Mina , Golmakan Mahbubeh Shaker
Published: July 2017

Scale morphology and its structural details were studied with morphometry, geometric morphometrics, and scanning electron microscopy in five IranianAphaniusspecies and examined comparatively with molecular phylogeny. Scales were cycloid and circular inA. farsicusTeimori, Esmaeili & Reichenbacher andA. vladykoviCoad, cycloid and polygonal inA. isfahanensisHrbek, Keivany & Coad andA. sophiae(Heckel), and were spined and polygonal inA. disparRüppell. Univariate analysis indicated that the relative length of anterior margin of radii played a significant role in the separation of some species studied (P < 0.05). Canonical Variates Analysis (CVA) based on seven landmarks showed clear separation between the Iranian inland and inland-relatedAphaniusspecies (IIRAS) group (four species) and the brackish water species (A. dispar). The lepidonts were conical in the IIRAS group with the exception ofA. isfahanensis(rounded) and were rounded inA. dispar. Based on the basal position of the brackish waterAphaniusspecies in the phylogenetic trees of the genusAphanius,it can be assumed that the presence of rounded lepidonts was a primary state in their scales or is the result of convergent evolution. Also, the polygonal state in the scales ofAphaniusspecies was a primitive shared character state.

Published: July 2017

The incidence of severe consecutive repetition of lordosis-kyphosis involving three flexions was reported in a specimen of the atherinid fish Atherina boyeri Risso. The values for the angles lay between the lines passing through the sides of the vertebral column and enclosing the curvatures, and the depth of the curvatures of the angles was obtained. Also, the ratio of the vertebral column to the fish total length of deformed and normal specimens of this species was calculated. Possible causes for these anomalies are discussed.
Allium cepa root meristem cells under osmotic (sorbitol) and salt (NaCl) stress in vitro
Authors: Kiełkowska Agnieszka
Published: July 2017

The effects of various concentrations of sorbitol (100, 200 and 360 mM) and NaCl (100, 200 and 300 mM) on root meristem cells ofin vitro-culturedAllium cepaL. were analyzed after 10 and 20 days. Both root meristem cell cross-section area and nuclear volume decreased under osmotic and salt stress. The osmotic component of applied stresses had a greater impact on cell shrinkage, while ionic stress perturbed cell functioning, resulting in cell cycle arrest and various aberrations, affecting nucleus integrity. A concentration of 300 mM of NaCl in the culture medium caused complete inhibition of mitotic activity in onion root tip cells after 20 days of exposure. Analysis of the action of iso-osmotic concentrations of NaCl (200 mM) and sorbitol (360 mM) showed stronger mitodepressive effects of salt stress in comparison to osmotic stress.
Relationships Between Creativity and its Antecedents Before and After Training: The Role of Risk-Taking and Past Creative Experience
Authors: Perry Anna , Karpova Elena
Published: July 2017

This research examined the effects of past creative experience and attitude toward risk-taking on creativity before and after training. College students enrolled in a creativity course participated in the study. Creativity was assessed by independent experts and self-assessed by the participants. Based on the results, an inverted U-shape relationship was proposed between (a) past creative experience and risk-taking, and (b) risk-taking and self-assessed creativity. Risk-taking was related to self-assessed creativity before and after the training, but not expert-assessed creativity. Past creative experience was not related to creativity, self and expert-assessed, before and after the training.
Procrastination is Detrimental to Undergraduate Students’ Self-Rated Creativity: The Mediating Role of State Anxiety
Authors: Lim Jia-Wei , Phang Joo-Yee , Low Mei-Yan , Tan Chee-Seng
Published: July 2017

Procrastination has been found to negatively impact academic and job performance. However, little attention has been given to the effect of procrastination on creative performance. Moreover, past studies have mainly focused on the antecedent role of anxiety in procrastination. The impact of procrastination on anxiety is not clear, though literature has suggested that procrastination may induce anxiety. The primary question addressed in the present study is whether and how procrastination influences creativity. Some exceptional studies have indicated that procrastination allows incubation and hence is conducive to creativity. However, on the basis of the literature, we argued and hypothesized that procrastination may impair creativity through state anxiety. A total of 218 Malaysian undergraduate students were recruited via social networking sites and responded to a packet of online survey questionairres, including self-report of procrastination tendency, state and trait anxiety, and creativity. Results showed that procrastination was positively associated with state and trait anxiety and negatively correlated with creativity. A negative relationship was also observed between state and trait anxiety and creativity. In addition, mediation analysis supported our hypothesis that state anxiety mediates the relationship between procrastination and creativity after controlling for the effect of trait anxiety. Specifically, people tend to experience feeling anxious when they postpone task completion. The high level of anxiety, in turn, is negatively associated with creative performance. As a whole, the findings not only offer the first empirical evidence supportive of the detrimental effect of procrastination on creativity, but also reveal the underlying process. Future directions and limitations are also explored.

Authors: Ocieczek Aneta , Skotnicka Magdalena , Baranowska Kinga
Published: July 2017

The physical and adsorptive properties of three products of modified maize starch in terms of the susceptibility of starch granules to surface processes as affected by their physicochemical diversity was compared in this study, using five mathematical models. It was assumed that modification of native starch is an important factor affecting its adsorptive properties. The products under study differed significantly in terms of the distribution of the size and shape parameters of their granules. The Guggenheim, Anderson and de Boer equation, characterised by relatively low sums of square deviations and low and similar errors of their different parameters, was the most useful in the description of empirically determined isotherms of adsorption. Parameters of the Guggenheim, Anderson and de Boer equation were used to estimate the parameters of the product surface microstructure. Modification of native maize starch differentiated the size of the monolayer, specific surface of sorption, and characteristics of capillaries.

Published: July 2017

Context

Women with autoimmune Addison’s disease with normal ovulatory cycles but positive for steroid cell antibodies (StCA) have been considered at risk of premature ovarian insufficiency (POI).

Design

Thirty-three women younger than 40 years, with subclinical-clinical autoimmune Addison’s disease but with normally ovulatory menses, were followed up for 10 years to evaluate the long-term time-related variations of StCA, ovarian function and follicular reserve. All patients and 27 control women were investigated at the start and every year for the presence and titre of StCA (by indirect immunofluorescence), serum concentrations of anti-Mullerian hormone (AMH) and ovarian function at four consecutive menses every year.

Results

At the start of the study StCA were present in 16 women (group 1), at low/middle titres (≤1:32) in seven of them (43.8%, group 1A), at high titres (>1:32) in the remaining nine patients (group 1B, 56.2%), while they were absent from 17 patients (group 2). During the follow-up period, all women in group 1A remained StCA-positive at low/middle titres with normal ovulatory menses and normal gonadotrophin and AMH levels, while all patients in group 1B showed a further increase of StCA titres (1:128–1:256) and progressed through three stages of ovarian function. None of the patients in group 2 and controls showed the appearance of StCA or ovarian dysfunction during the follow-up.

Conclusions

The presence of StCA at high titres can be considered a good predictive marker of subsequent development of autoimmune POI. To single out the stages of autoimmune POI may allow a timely therapeutic choice in the subclinical and early clinical stages.
Androgen-responsive non-coding small RNAs extend the potential of HCG stimulation to act as a bioassay of androgen sufficiency

Published: July 2017

Background

It is unclear whether a short-term change in circulating androgens is associated with changes in the transcriptome of the peripheral blood mononuclear cells (PBMC).

Aims and methods

To explore the effect of hCG stimulation on the PBMC transcriptome, 12 boys with a median age (range) of 0.7 years (0.3, 11.2) who received intramuscular hCG 1500u on 3 consecutive days as part of their investigations underwent transcriptomic array analysis on RNA extracted from peripheral blood mononuclear cells before and after hCG stimulation.

Results

Median pre- and post-hCG testosterone for the overall group was 0.7 nmol/L (<0.5, 6) and 7.9 nmol/L (<0.5, 31.5), respectively. Of the 12 boys, 3 (25%) did not respond to hCG stimulation with a pre and post median serum testosterone of <0.5 nmol/L and <0.5 nmol/L, respectively. When corrected for gene expression changes in the non-responders to exclude hCG effects, all 9 of the hCG responders consistently demonstrated a 20% or greater increase in the expression ofpiR-37153andpiR-39248, non-coding PIWI-interacting RNAs (piRNAs). In addition, of the 9 responders, 8, 6 and 4 demonstrated a 30, 40 and 50% rise, respectively, in a total of 2 further piRNAs. In addition, 3 of the responders showed a 50% or greater rise in the expression of another small RNA,SNORD5. On comparing fold-change in serum testosterone with fold-change in the above transcripts, a positive correlation was detected forSNORD5(P = 0.01).

Conclusions

The identification of a dynamic and androgen-responsive PBMC transcriptome extends the potential value of the hCG test for the assessment of androgen sufficiency.
Management impact: effects on quality of life and prognosis in MEN1
Authors: Marini Francesca , Giusti Francesca , Tonelli Francesco , Brandi Maria Luisa
Published: July 2017

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant endocrine tumor syndrome, caused by inactivating mutations of the MEN1 tumor suppressor gene at 11q13 locus, which predisposes to develop tumors in target neuroendocrine tissues. As the positional cloning and identification of the causative gene in 1997, genetic diagnosis, by the sequencing-based research of gene mutations, has become an important tool in the early and differential diagnosis of the disease. Application of the genetic test, in MEN1 index cases and in first-degree relatives of mutated patients, has been constantly increasing during the last two decades, also thanks to the establishment of multidisciplinary referral centers and specific genetic counseling, and thanks to the wide availability of high throughput instruments for gene sequencing and gene mutation identification. The MEN1 genetic test helps the specific diagnosis of probands, and allows the early identification of asymptomatic carriers, strongly contributing, together with progressions in tumor diagnostic techniques and in pharmacological and surgical therapeutic approaches, to the reduction of morbidity and mortality associated with the syndrome. International clinical guidelines for MEN1 have been drafted by panels of specialists in the field, with the main goal to improve the management of the disease and grant patients a better quality of life. Here, we review main recommendations and suggestions derived by the last published general guidelines in 2012, and by most recent published studies about MEN1 syndrome diagnosis, clinical management, therapeutic approaches and patients’ quality of life.

Compared with age-matched men, premenopausal women are largely protected from coronary artery disease, a difference that is lost after menopause. The effects of oestrogens are mediated by the activation of nuclear receptors (ERα and ERβ) and by the G protein-coupled oestrogen receptor (GPER). This study aims to evaluate the potential role of GPER in coronary circulation in female and male rats. The baseline coronary perfusion pressure (CPP) and the concentration–response curve with a GPER agonist (G-1) were evaluated in isolated hearts before and after the blockade of GPER. GPER, superoxide dismutase (SOD-2), catalase and gp91phox protein expression were assessed by Western blotting. Superoxide production was evaluated ‘in situ’ via dihydroethidium fluorescence (DHE). GPER blockade significantly increased the CPP in both groups, demonstrating the modulation of coronary tone by GPER. G-1 causes relaxation of the coronary bed in a concentration-dependent manner and was significantly higher in female rats. No differences were detected in GPER, SOD-2 and catalase protein expression. However, gp91phox expression and DHE fluorescence were higher in male rats, indicating elevated superoxide production. Therefore, GPER plays an important role in modulating coronary tone and reactivity in female and male rats. The observed differences in vascular reactivity may be related to the higher superoxide production in male rats. These findings help to elucidate the role of GPER-modulating coronary circulation, providing new information to develop a potential therapeutic target for the treatment of coronary heart disease.
Adiponectin limits differentiation and trophoblast invasion in human endometrial cells

Published: July 2017

Successful human embryo implantation requires a proper differentiation of endometrial stromal cells (ESCs) into decidual cells, during a process called decidualization. ESCs express specific molecules, such as prolactin, insulin-like growth factor-binding protein-1 (IGFBP-1) and connexin-43. Decidual cells are also involved in the control of trophoblast invasion, by secreting various factors, such as matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). Adiponectin is an adipokine with insulin-sensitizing, anti-inflammatory and anti-proliferative effects. At the embryo–maternal interface, adiponectin promotes differentiation and invasion of human trophoblastic cells. We hypothesize that the effects of adiponectin on endometrium could counteract its pro-invasive effects previously described in the human trophoblast. In this context, we have firstly demonstrated that adiponectin downregulates IGFBP-1 and connexin-43 mRNA expressions, as well as prolactin secretion in ESCs, suggesting an anti-differentiative effect of adiponectin. Secondly, we found that invasive capacities of trophoblastic cell line HTR-8/SVneo are reduced in the presence of conditioned media from ESC cultured in the presence of adiponectin. Adiponectin’s anti-invasive action is associated with a decreased activity of MMP-2 and MMP-9, and an increased TIMP-3 mRNA expression in ESCs. Finally, adiponectin receptors (ADIPOR1 and ADIPOR2) knockdown abolishes the anti-differentiative and anti-invasive effects of adiponectin in human ESCs. Altogether, our results suggest that adiponectin reduces the decidualization process and inversely induces the production of endometrial factors that limit trophoblast invasion. Thus, through a dual control in trophoblast and endometrial cells, adiponectin appears as a pivotal actor of the embryo implantation process.
miR-30e targets GLIPR-2 to modulate diabetic nephropathy: in vitro and in vivo experiments
Authors: Zhao Dong , Jia Jinhua , Shao Hong
Published: July 2017

The objectives of this study are to investigate the effect of miR-30e targeting GLIPR-2 on the pathological mechanism of DN. The renal tissues of db/db and db/m mice at different age of weeks were stained with PAS. qRT-PCR was applied to detect the expression of miR-30e and GLIPR-2, not only in the renal tissues of mice but also in the renal tubular epithelial cells (RTECs). By luciferase reporter gene assays, we found the 3′-UTR of the GLIPR-2 mRNA as a direct target of miR-30e. The RTECs cultured in high glucose were divided into blank control, NC, miR-30e mimics, miR-30e inhibitors, miR-30e inhibitor + si-GLIPR-2 and si-GLIPR-2 groups. MTT and flow cytometry were utilized to measure the proliferation and apoptosis of RTECs, while qRT-PCR and Western blot to detect the expression of GLIPR-2- and EMT-related factors. The following results were obtained: In the renal tissues of over 8-week-old db/db mice and the RTECs cultured for 6 h in high glucose, miR-30e was downexpressed while GLIPR-2 was upregulated in a time-dependent manner. Besides, overexpression of miR-30e and si-GLIPR-2 can not only greatly improve the proliferation of RTECs cultured in high glucose, but also downregulate the apoptosis rate of RTECs and the expressions of GLIPR-2, vimentin, α-SMA, Col-I and FN and upregulate E-cadherin. Moreover, si-GLIPR-2 can reverse the proliferation reduction, GLIPR-2 and EMT occurrence caused by the downexpression of miR-30e in RTECs. In conclusion, miR-30e is downregulated in DN, and the overexpression of miR-30e can inhibit GLIPR-2, promote the proliferation of RTECs and inhibit EMT, ultimately avoid leading to renal fibrosis in DN.
Molecular forms of ruminant BMP15 and GDF9 and putative interactions with receptors
Authors: Heath Derek A , Pitman Janet L , McNatty Kenneth P
Published: July 2017

Bone morphogenetic factor 15 (BMP15) and growth differentiation factor 9 (GDF9) are oocyte-secreted factors with demonstrable effects on ovarian follicular development and ovulation rate. However, the molecular forms of BMP15 and GDF9 produced by oocytes remain unclear. The aims herein, using Western blotting (WB) procedures with specific monoclonal antibodies (mabs), were to identify the molecular forms of BMP15 and GDF9 synthesised and secreted by isolated ovine (o) and bovine (b) oocytes in vitro. The mabs were known to recognise the biological forms of BMP15 or GDF9 since they had previously been shown to inhibit their bioactivities in vitro and in vivo. Using recombinant variants of oBMP15 and oGDF9, including a cysteine mutant form of oBMP15 (S356C) and a human (h) BMP15:GDF9 heterodimer (cumulin), it was established that the mabs were able to identify monomeric, dimeric, promature and higher-molecular-weight forms of BMP15 and GDF9 and cumulin (GDF9 mab only). After using non-reducing, reducing and reducing + cross-linking conditions, the major oocyte-secreted forms of o and b BMP15 and GDF9 were the cleaved and uncleaved monomeric forms of the promature proteins. There was no evidence for dimeric or heterodimeric forms of either mature BMP15 or GDF9. From in silico modelling studies using transforming growth factor beta (TGFB), activin or BMP crystal templates, and both present and previously published data, a model is proposed to illustrate how the monomeric forms of BMP15 and GDF9 may interact with their type II and type I cell-surface receptors to initiate the synergistic actions of these growth factors.
Contrasting Determinants of Mutation Rates in Germline and Soma

A number of genomic features influence regional mutation rates in germline and soma. To examine if some factors behave differently in the two tissue...

Recent studies of somatic and germline mutations have led to the identification of a number of factors that influence point mutation rates, including CpG methylation, expression levels, replication timing, and GC content. Intriguingly, some of the effects appear to differ between soma and germline: in particular, whereas mutation rates have been reported to decrease with expression levels in tumors, no clear effect has been detected in the germline. Distinct approaches were taken to analyze the data, however, so it is hard to know whether these apparent differences are real. To enable a cleaner comparison, we considered a statistical model in which the mutation rate of a coding region is predicted by GC content, expression levels, replication timing, and two histone repressive marks. We applied this model to both a set of germline mutations identified in exomes and to exonic somatic mutations in four types of tumors. Most determinants of mutations are shared: notably, we detected an effect of expression levels on both germline and somatic mutation rates. Moreover, in all tissues considered, higher expression levels are associated with greater strand asymmetry of mutations. However, mutation rates increase with expression levels in testis (and, more tentatively, in ovary), whereas they decrease with expression levels in somatic tissues. This contrast points to differences in damage or repair rates during transcription in soma and germline.
High genetic connectivity and Population Expansion of Scomber japonicus in the Northern Humboldt Current System revealed by mitochondrial D-Loop region sequences
Authors: Barahona Padilla Sergio Paolo , Oré Chávez Daniel Saúl , Quiroz Baza Roger Walter
Published: July 2017

The Chub mackerel (Teleostei: Scombridae) supports an important fishery in the Southeastern Pacific, however, its population genetics status is currently unknown. In the present study the population genetic structure, gene flow and historical demography of this resource in the Northern Humboldt Current System were examined. Samples were collected between 2103 and 2014 from three fishing points off the Peruvian coast (Paita, Ventanilla and Ilo) and analyzed using mitochondrial D-Loop region sequences. A total of 29 polymorphic sites and 35 haplotypes were found in 72 individuals. Moderate haplotype diversity and very low levels of nucleotide diversity were found. Analysis of gene flow showed high levels of connectivity among sampling areas. Analysis of molecular variance, pairwise comparisons and genetic differentiation tests confirmed the lack of genetic structuring. These analyses suggest that analyzed sampling locations can be considered as a single gene pool. Migratory behavior, the high dispersal potential of early stages and the lack of oceanographic barriers can explain its genetic homogeneity along the Peruvian sea. The historical demography was also examined. Neutrality testing, mismatch distribution and Bayesian skyline plot suggested a population expansion scenario that took place during the Late Pleistocene. This study provides novel information about population genetics of the chub mackerel from the Southeastern Pacific.

Among the pollutants one of the main factor is heavy metals. Cadmium, a typical representative of this group has a very toxic effect on both the animal and the human. It is not involved in the vital processes of living organisms. Instead, exceeding the maximum permissible levels of cadmium has negative affects on animal, and accumulation in the tissues, is a threat to human life - the consumer of animal products. The results of research show efficiency of dry apple pulp and dry beet pulp as natural detoxicant of heavy metals, including cadmium, in the body of young pigs. Experimentally proved that the cadmium content in complete feed with the maximum permissible level (1 mg/kg) predetermined decrease of average daily gain of pigs experimental group, compared with the control, by 10.8% and increase of feed conversion by 9.8%. The introduction to the mixed fodder of dry apple pulp (45 g/kg) or dry beet pulp (45 g/kg) with of the same cadmium content contributed that the productivity of animals, the cost of feed for 1 kg of growth, slaughter weight, carcass yield, weight mascara and economic efficiency of fattening young pigs approaching to the level of control. In addition, the use of dry apple pulp and dry beet pulp as natural forage detoxicant in diets of young pigs helps significantly (P <0.05-0.001), reduction of heavy metals, including cadmium in products of slaughter (meat, bacon, liver, kidney, heart), which increases their purity, environmental safety and competitiveness.

Published: July 2017

Las plantas introducidas se han convertido en un componente importante de la vegetación de casi todos los países del mundo. Tanto las bases de datos como listas de especies introducidas nos permiten comparar su distribución y sus efectos en los ecosistemas naturales en diferentes regiones, dándonos un mejor conocimiento de su ecología para desarrollar estrategias preventivas. Aquí presentamos el análisis de 1048 especies de plantas introducidas en Costa Rica, pertenecientes a 609 géneros y 148 familias. Consideramos que este número de especies introducidas es una subestimación, que debe aumentar cuando se genere más investigación sobre el tema. La familia con el mayor número de especies introducidas es Poaceae (118 spp.), seguida por Fabaceae con 74. Del total, 116 familias aportan 10 o menos especies. El 55% de las especies introducidas son hierbas. El uso más común que se les da a las especies de plantas introducidas en Costa Rica es ornamental (52%). Un 8.9% de las especies tienen varios usos, como ornamentales, medicinales y comestibles. En Costa Rica es escasa o nula la información sobre el estado poblacional de las especies introducidas; no existen datos del 31% de las especies aquí registradas. El resto son especies cultivadas (47%) o naturalizadas (22%). El origen geográfico de estas especies es muy variado; sin embargo, Asia tropical (19.4 %) y Sudamérica (18.6%) son las regiones de origen del mayor número de especies introducidas en Costa Rica. Aquí presentamos el primer estudio de las plantas introducidas en Costa Rica y, a nuestro conocimiento, el primer análisis taxonómico de la flora introducida en la región neotropical. El catálogo resultante de las plantas introducidas en Costa Rica se hallará en http://i3n.iabin.net (ver dirección completa al final de Bibliografía consultada).

In this paper we summarize the taxonomic history of Pleurothallis crocodiliceps Rchb.f. and demonstrate that the species described by Reichenbach did not possess the stereotypical minute, pubescent, tri-lobed lip, with basal lobes modified into “horns”. The first two species described with such a lip were P. arietina and P. nelsonii. Rather than a single widely distributed, variable species, with a morphologically constant lip, P. crocodiliceps, we recognize the P. arietina-P. nelsonii species complex. Herein we describe four new species in this complex and discuss the morphological characters useful in distinguishing among the members of the complex. We also discuss the nature of the lip possessed by members of this complex and propose that it may mimic a female insect luring a male fly into pollinating the flower by pseudocopulation.
Does Partisanship Stop at Scandal’s Edge? Partisan Resiliency and the Survival of Political Scandal
Authors: Cortina Jeronimo , Rottinghaus Brandon
Published: July 2017

The outbreak of political scandal depresses the approval ratings of the individuals involved, especially the president.  Yet, less is known about the partisan effects of approval ratings during scandal, especially the “stickiness” of partisan ties to leaders involved in scandal.  Using a survey experiment, we expose respondents to manufactured news coverage of both illegal and not illegal (mismanaged policy) activities involving President Obama.  The results demonstrate that the President’s co-partisans are more likely to approve of the President and less likely to desire to impeach the president, even after being informed about illegal activity.  In contrast, out partisans are more likely to demand the President’s impeachment for both illegal and not illegal activity.  This article provides evidence of how partisanship persists (and even expands) during presidential scandals and how partisan linkages are important to surviving scandal.

Authors: Campedelli Maria Coeli , Takito Clarinda , Sancinetti Tania Regina , Benko Maria Antonieta
Published: July 2017

As autoras analisam a problema enfrentado pela Direção de Enfermagem de um hospital, referente ao cálculo do número de pessoal necessário para a prestação da assistência de enfermagem aos pacientes. Referem que os hospitais, numa fase inicial, poderão utilizar-se de fórmulas encontradas na literatura, mas enfatizam que, posteriormente, os cálculos devem ser refeitos, levando em consideração o número de horas diárias de cuidados que, naquela situação, os pacientes requerem, e outros fatores locais que interferem na assistência de enfermagem.
AVALIAÇÃO DO ESTADO NUTRICIONAL DE FERRO DE ESTUDANTES UNIVERSITÁRIOS DO SEXO FEMININO
Authors: Fujimori Elizabeth , Salum Maria Josefina Leuba , Shima Hisako
Published: July 2017

Foi realizado um estudo para avaliar o estado nutricional de ferro, envolvendo 47 estudantes universitários do sexo feminino, cujas dietas continham, em média, somente 72% da recomendação para o ferro. Os resultados mostram que apesar do baixo consumo do mineral, a concentração de hemoglobina e o valor do hematócrito encontravam-se dentro dos limites de normalidade. Em face disto, discute-se a possibilidade de as reservas orgânicas de ferro estarem baixas ou esgotadas.
O CORONARIOPATA E O AMBIENTE DA UNIDADE DE TERAPIA INTENSIVA: Estudo da influência dos procedimentos invasivos
Authors: Padilha Katia Grillo
Published: July 2017

Trata-se de um estudo sobre a influencia da quantidade de procedimentos invasivos aos quais é submetido um paciente assistido em Unidade de Terapia Intensiva e sua relação quanto à percepção desse ambiente. Foram entrevistados 100 pacientes com diagnóstico médico de Insuficiência Coronariana Aguda, internados numa mesma UTI e divididos em Grupo A, aqueles com maior número de procedimentos invasivos, e Grupo B, com menor número desses procedimentos. O estuda estatístico não revelou diferença entre os grupos A e B, tanto em relação à quantidade de problemas, quanto à sua natureza. A maioria dos pacientes dos dois grupos referiu problemas relacionados com a internação e, inversamente, a minoria percebeu sons e imagens que chamaram a sua atenção no ambiente da UTI. Dos problemas referidos pelos pacientes, a maioria foi de origem ambiental, com predomínio daqueles relativos à separação da família.

O ENSINO DA METODOLOGIA DE ASSISTÊNCIA DE ENFERMAGEM: RESPONSABILIDADE DA DISCIPLINA DE FUNDAMENTOS DE ENFERMAGEM
Authors: Santos Leila Conceição Rosa dos , Silva Sandra Honorato da , Laganá Maria Teresa Cícero , Araújo Thelma Leite de
Published: July 2017

As autoras, professoras de Fundamentos de Enfermagem, descrevem duas experiencias de ensino da metodologia da assistência de enfermagem, em curso de graduação, para as quais foram utilizados dois tipos diferentes de campo de prática; no primeiro, o pessoal de enfermagem não utilizava a metodologia de assistência de enfermagem e, no segundo, a utilização dessa metodologia estava implantada. Dessas experiências, duas foram as conclusões: 1º — A atitude dos alunos, que atuaram no primeiro campo de prática mencionado, era pessimista: consideravam eles, que a adoção da metodologia da assistência de enfermagem só era possível como atividade didática, mas não como atividade profissional; ao passo que a atitude dos alunos que praticaram em campo onde essa metodologia estava implantada foi posiva sobre a conveniência de sua adoção; 2° — Os alunos de Fundamentos de Enfermagem, devido à falta de conhecimento de patologia, não estão ainda preparados para identificar os problemas de enfermagem e propor soluções. As autoras apresentam proposta sobre a gradação do ensino de metodologia da assistência de enfermagem no decorrer do curso, a fim de torná-lo mais efetivo.
