Authors: Quiroz Ramírez Arturo , Terán Gilmore Amador , Serrano Medrano Montserrat
Published: January 2018

Se presenta una comparación de la respuesta sísmica, así como del potencial de impacto ambiental, de dos sistemas estructurales. Ambos cuentan con 24 niveles y 114 metros de altura y están localizados en la Zona del Lago de Ciudad de México. El primero, que se denomina tradicional, utiliza marcos compuestos de concreto reforzado y acero estructural resistentes a momento y contravientos concéntricos. El segundo, denominado innovador, está estructurado con rejillas rígidas perimetrales y marcos de acero. A pesar de sus menores peso, y rigidez y resistencia laterales, el sistema innovador exhibe un mejor desempeño sísmico caracterizado por la aparición, para la excitación sísmica de diseño, de daño incipiente en alrededor del 8% de sus elementos sismorresistentes. Además, la construcción del sistema innovador reduce en dos tercios las emisiones de gases de efecto invernadero en relación con el sistema tradicional. El ejemplo presentado aquí aporta una idea de los beneficios que el uso de sistemas innovadores puede traer dentro de las prácticas mexicanas de diseño y edificación.

Background and objectives: The objective of this study was to establish reference values for hand grip strength, compare the results obtained with Collin and Jamar type dynamometers and determine their association with anthropometric and lean mass measurements.Material and methods: This cross-sectional population-based study was undertaken in Pizarra (Málaga, Spain). The grip strength of the dominant hand was measured using Collin and Jamar dynamometers. Skinfolds (triceps, abdominal, biceps of dominant arm and subscapular) were measured, and body composition was estimated. Eight hundred seventeen adults randomly selected from the census were recruited. Dynamometry reference values are presented for the dominant hand, by gender and age groups.Results: No determinations could be made with the Collin dynamometer in 69 women due to the difficulty in grasping the dynamometer. We found significant positive correlations between the measurements with Jamar and Collin dynamometers (r=0.782; p<0.001) and between grip strength and LMI, determined by both dynamometers (r=0.538, p<0.001 and r=0.462, p<0.001 respectively). Malnourished patients according to LMI had significantly lower grip strength than normally nourished patients (p<0.001 por Jamar; p<0.02 for Collin).Conclusions: Dynamometry reference values in the Spanish population are presented. We recommend the use of the Jamar type dynamometer versus the Collin type dynamometer. Hand grip dynamometry is associated with lean mass which confirms its usefulness in nutritional assessment.

Unfolding Cardiac Amyloidosis –From Pathophysiology to Cure
Authors: Ablasser Klemens , Verheyen Nicolas , Glantschnig Theresa , Agnetti Giulio , Rainer Peter P.
Published: January 2018

Deposition of amyloidogenic proteins leading to the formation of amyloid fibrils in the myocardium causes cardiac amyloidosis. Although any form of systemic amyloidosis can affect the heart, light-chain (AL) or transthyretin amyloidosis (ATTR) account for the majority of diagnosed cardiac amyloid deposition. The extent of cardiac disease independently predicts mortality. Thus, the reversal of arrest of adverse cardiac remodeling is the target of current therapies. Here, we provide a condensed overview on the pathophysiology of AL and ATTR cardiac amyloidoses and describe treatments that are currently used or investigated in clinical or preclinical trials. We also briefly discuss acquired amyloid deposition in cardiovascular disease other than AL or ATTR.
Colchicine in Neurosurgery
Authors: Drosos Evangelos , Giakoumettis Dimitrios , Themistocleous Marios S.
Published: January 2018

Background:

Colchicine is an ancient drug. Many uses have been reported in medical books and reports
through the centuries. Currently the understanding of its mechanism of action has opened new horizons to
its use.

Objective:

This article aims to discuss the use of colchicine in various neurosurgical conditions.

Methods:

A pubmed database and clinical trials search was performed, using the key words “colchicine”, “Neurosurgery”,
“low back pain”, “stroke” and glioma”.

Results:

Various reports were found contemplating the use of colchicine in chronic low-back pain. The effect of
the drug on neutrophil chemotaxis and its role as an anti-inflammatory agent has been the main argument upon
which such use of colchicine has been structured. These characteristics have been the key to initiate colchicine as
a preventive agent in vascular conditions. Furthermore, as colchicine is an antimitotic drug, it is currently being
studied as a potential anti-glioma agent. However, the narrow therapeutic index of the drug is a discouraging
factor in clinical application of colchicine in these entities. Therefore, colchicine derivatives that can exert the
same effectiveness in lower doses are being studied, forming a new direction in colchicine use.

Conclusion:

Colchicine is a drug that over the years has shown promising results in certain neurosurgical entities.
Its derivatives or potential colchicine-like agents might have a more significant place in neurosurgical practice.
Mutations of Nuclear and Mitochondrial Genomes as Potential Targets for the Treatment of Metabolic Syndrome
Authors: Galitsyna Elena V. , Zhelankin Andrey V. , Sobenin Igor A. , Orekhov Alexander N.
Published: January 2018

In addition to external factors, such as exercise, food and the environment, genetic predisposition
makes great contribution to the development of metabolic disorders and cardiovascular disease. This review is
aimed to examine the genetic basis of complex metabolic disorders conventionally described as "metabolic syndrome"
(MetS), with the special focus on currently known mutations in the nuclear and mitochondrial genomes,
which are associated with both the individual components of MetS and combinations thereof, and also on the
studies of the relationship of MetS phenotype as a binary trait. The defects in the mitochondrial genome should be
considered as one of the possible genetic reasons leading to MetS. It is known that mitochondrial dysfunction is
closely associated with metabolic disorders, as mitochondria are the center of energy metabolism. Consequently,
the changes in mitochondrial genes and their functions affect regulation of metabolism. Until now, the role of
mitochondrial DNA damage in the development of cardiovascular diseases, age-related and metabolic disorders is
still poorly understood. The results of performed studies would help assessing the role of mitochondrial DNA
mutations in susceptibility to metabolic syndrome and related metabolic diseases.

Published: January 2018

The prevalence of allergic diseases is increasing worldwide. It is estimated that more than 30% of the
world population is now affected by one or more allergic conditions and a high proportion of this increase is in
young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together
with the detection of allergen-specific IgE. Accurate diagnosis of allergies opens up therapeutic options.
Allergen specific immunotherapy is the only successful disease-modifying therapy for IgE-mediated allergic
diseases. New therapeutic strategies have been developed or are currently under clinical trials. Besides new
routes of administration, new types of allergens are being developed. The use of adjuvants may amplify the
immune response towards tolerance to the antigens. In this review, we analyze different antigen-specific immunotherapies
according to administration route, type of antigens and adjuvants, and we address the special case
of food allergy.

Published: January 2018

Introduction: Despite the proven efficacy of anti-thrombotic, lipid-lowering, anti-hypertensive therapies
and lifestyle modification changes for secondary ischemic stroke prevention, the risk of recurrent stroke,
coronary events and vascular death remains substantial even for patients treated with high rates of established
secondary preventive medications.

Methods:

In the present review, we summarize available literature data on the association between systemic inflammation
and symptomatic atherosclerosis including recurrent cerebral ischemia. We also highlight the potential
role of colchicine in the suppression of atherosclerosis-induced inflammation, plaque stabilization and thromboembolism
prevention.

Results:

Accumulating evidence suggests that inflammation is of key importance in the pathophysiology of atherosclerotic
plaque de-stabilization and thromboembolism, with inflammatory cells being involved in all stages of
atherosclerosis development. Therefore, anti-inflammatory therapies targeting the atherosclerotic plaque inflammation
may be important contributors in plaque stabilization and in the prevention of thromboembolic events.
Colchicine is known to have multiple anti-inflammatory properties including inhibition of microtubule polymerization,
leading to reduced secretion in monocyte-macrophages. Currently the randomized controlled CONVINCE
trial is enrolling stroke patients to evaluate the effect of a daily low-dose of colchicine in reducing the rate of
recurrent stroke and major vascular events.

Conclusion:

Inflammatory pathways seem to be key mediators in the development of atherosclerotic process,
atheromatous plaque destabilization and thromboembolism. Colchicine as a novel therapeutic agent could be a
safe and effective inhibitor of the inflammation cascade in patients with extra- or intracranial atherosclerosis or
arteriolosclerosis, resulting in reduced vascular events.

Authors: Lazaros George , Imazio Massimo , Brucato Antonio , Vlachopoulos Charalambos , Lazarou Emilia , Vassilopoulos Dimitrios , Tousoulis Dimitris
Published: January 2018

Background:

Colchicine is an old drug originally employed for the treatment of inflammatory disorders
such as acute gout and familiar Mediterranean fever.

Methods:

In the past few decades, colchicine has been at the forefront of the pharmacotherapy of several cardiac
diseases, including acute and recurrent pericarditis, coronary artery disease, prevention of atrial fibrillation and
heart failure. In this review, we have summarized the current evidence based medicine and guidelines recommendations
in the specific context of pericardial syndromes.

Results:

Colchicine has been firstly engaged in the treatment of recurrent pericarditis of viral, idiopathic and
autoimmune origin. Shortly thereafter colchicine use has been expanded to the primary prevention of recurrences
in patients with a first episode of pericarditis depicting similarly good results. The acquisition of high quality
scientific data in the course of time from prospective randomized placebo-controlled trials and metanalyses have
established colchicine as first line treatment option in acute and recurrent pericarditis, on top of the conventional
treatment. The only concerns related to the use of colchicine are the side effects (mainly gastrointestinal intolerance)
which although generally not serious, may account for treatment withdrawal in some cases.

Conclusion:

Colchicine has been established as a first line medication in the treatment of acute (first episode) and
recurrent pericarditis on top of the conventional treatment as well as for the prevention of postpericardiotomy
syndrome. It depicts a good safety profile with gastrointestinal intolerance being the most common side effect.

Method: We have described an efficient and green process for the synthesis of the one-pot three-component
synthesis of 3,4-dihydropyrano[3,2-c]chromenes from the reaction between 4-hydroxy-coumarin with
malononitrile and aldehydes in the presence of catalytic amount of magnetic nanoparticles tag: piperidinium
benzene-1,3-disulfonate ionic liquid as a novel and powerful nano ionic liquid with good to excellent yields
and in a short reaction time in water solvent at 60 °C.

Result: The main advantage of this process is the simplicity of the work-up and the products can be isolated
without chromatography.

Conclusion: We suggest that the method has also various additional advantages such as low loading of catalyst,
clean reaction, which makes it a suitable and noteworthy approach for the synthesis of 3,4-
dihydropyrano[3,2-c]chromenes.

Published: January 2018

Purpose: Some aromatase inhibitors are FDA-approved agents as first-line therapy in the treatment of
endocrine-responsive breast cancer. In this study, we aimed to develop new azole derivatives with higher specificity
and potency.

Methods:

New aromatase inhibitors were designed by Molecular Operating Environment (MOE) software and
synthesized in a one-step SN2 reaction. These compounds were characterized by melting point, 1H- and 13CNMR,
elemental analysis and mass spectra. The in vitro and in vivo aromatase inhibition of these compounds
was evaluated using the Estrone ELISA assay, and by measuring the inhibition of androstenedione-induced
uterine hypertrophy. The selectivity of aromatase inhibition was investigated by the inhibition of ACTH stimulation
on the plasma concentrations of aldosterone and cortisol.

Results:

Docking simulations showed that four new azole derivatives could efficiently interact with enzyme
active sites. The in vitro aromatase-inhibition assay showed that the compounds 1,3,5-tris(imidazol-1-
ylmethyl)benzene (3b) and 1,3-Bis(imidazole-1- ylmethyl) benzene (3d) effectively inhibited aromatase, with
IC50 values of 0.2 nM and 6.8 nM, respectively; these values were similar to known aromatase inhibitor letrozole
(IC50 0.3 nM). The in vivo aromatase-inhibitory potency of compound 3b was similar to letrozole, although
compound 3b acted more selectively.

Conclusion:

This report introduced a new compound that can be considered as a new lead for further investigation
to explore more-potent and more-selective aromatase inhibitors.

Published: January 2018

La ramificación de los árboles tiene un impacto económico importante en las plantaciones forestales, ya que afecta la calidad de la madera. La posibilidad de incorporar estas características en un programa de mejora genética depende de su heredabilidad y estructura genética con la productividad de los árboles. El objetivo del estudio fue estimar la repetibilidad de los parámetros genéticos de las características de ramificación en progenies de Pinus patula a 7 años y 10 años de edad, así como su relación genética con la tasa de crecimiento de los árboles. Las características de ramificación (número de verticilos, número, diámetro y ángulo de ramas, y presencia de defectos en la ramificación) y crecimiento (altura, diámetro y volumen del tronco) se evaluaron en 84 familias de polinización libre. Con estos datos se estimó la heredabilidad y las correlaciones genéticas, fenotípicas y edad-edad de las características. El control genético de las características de ramificación varío de nulo a moderado (0.00 ≤ h2i ≤ 0.23; 0.00 ≤ h2f ≤ 0.42), pero fue estable en las dos edades. Las características de ramificación con variación genética mostraron una estructura genética favorable con las de crecimiento. El número de verticilos y el diámetro de ramas ajustado tuvieron una correlación negativa (-0.60 ≤ rg ≤ -0.01), y el ángulo de ramas una correlación positiva (0.14 ≤ rg ≤ 0.47), con el crecimiento de los árboles. La repetibilidad de la estructura genética de las características de ramificación y crecimiento de los árboles fue alta, en términos de las correlaciones edad-edad (0.58 ≤ rg ≤ 0.94; 0.83 ≤ rpf ≤ 1.00) y del coeficiente de correlación entre las matrices de correlaciones genéticas y fenotípicas en las dos edades (r ≥ 0.86). La selección individual o familial para aumentar la productividad en esta población causaría mejoras en la ramificación (menor número de verticilos y ramas más delgadas, con ángulo mayor) y, por lo tanto, en la calidad de la madera.

The usefulness of cone-beam computed tomography gray values for alveolar bone linear measurements
Authors: Padala Soumya , Tee Boon Ching , Beck Frank M. , Elias Kathy , Kim Do-Gyoon , Sun Zongyang
Published: January 2018

Objectives:

To test a proof-of-concept that the accuracy and reliability of alveolar bone height measurements from orthodontic grade (large field-of-view [FOV], large voxel-size) cone-beam computed tomography (CBCT) images may be improved by using pixel gray values.

Materials and Methods:

Twenty fresh cadaver pig heads underwent CBCT scans (17 × 23 cm FOV, 0.4-mm voxel size). Buccal alveolar bone heights of maxillary first molars were measured using the conventional vision-based (VB) and the proposed gray value–assisted (GVA) methods. The GVA methods entailed localization of landmarks through observation of gray value pattern changes across tissue boundaries followed by mathematical calculation of distances between landmark pixels. Interrater reliability and accuracy of CBCT measurements made by all methods were statistically analyzed by comparing with physical measurements (gold standards).

Results:

The interrater reliability of CBCT measurements made by GVA methods was comparable to physical measurements but higher than those made by the VB method. The GVA (bend-down pattern) method yielded average measurements similar to physical measurements, while those obtained by the VB and the GVA (straight pattern) methods were significantly larger (repeated measures analysis of variance, P < .001). The GVA (bend-down pattern) method also produced significantly more measurements within one voxel size of physical measurements than did the VB and GVA (straight pattern) methods (Chi-square tests, P < .017).

Conclusions:

These data confirm a concept that local gray value change patterns may be used to improve the accuracy and reliability of alveolar bone height measurement from large FOV and large voxel-size CBCT images.
The cervical vertebral maturation method: A user's guide
Authors: McNamara James A. , Franchi Lorenzo
Published: January 2018

The cervical vertebral maturation (CVM) method is used to determine the craniofacial skeletal maturational stage of an individual at a specific time point during the growth process. This diagnostic approach uses data derived from the second (C2), third (C3), and fourth (C4) cervical vertebrae, as visualized in a two-dimensional lateral cephalogram. Six maturational stages of those three cervical vertebrae can be determined, based on the morphology of their bodies. The first step is to evaluate the inferior border of these vertebral bodies, determining whether they are flat or concave (ie, presence of a visible notch). The second step in the analysis is to evaluate the shape of C3 and C4. These vertebral bodies change in shape in a typical sequence, progressing from trapezoidal to rectangular horizontal, to square, and to rectangular vertical. Typically, cervical stages (CSs) 1 and CS 2 are considered prepubertal, CS 3 and CS 4 circumpubertal, and CS 5 and CS 6 postpubertal. Criticism has been rendered as to the reproducibility of the CVM method. Diminished reliability may be observed at least in part due to the lack of a definitive description of the staging procedure in the literature. Based on the now nearly 20 years of experience in staging cervical vertebrae, this article was prepared as a “user's guide” that describes the CVM stages in detail in attempt to help the reader use this approach in everyday clinical practice.
State-building projects of the Tatar and Bashkir people in 1917–1920
Authors: Galiakhmetov Ilgam Ishbulatovich ,   Bashkir State University
Published: January 2018

This paper is an attempt to provide an objective coverage of the history of various projects for solving the Tatar-Bashkir problem in 1917–1920 and show the attitude of the leaders of the Bashkir national movement and Tatar public organizations to these projects. The main objective of the bourgeois-nationalist and Soviet state-building projects was the creation of the joint autonomous republic of two main Turkic-speaking people in Ural-Volga region, i.e. the Tatars and Bashkirs. These projects have not been implemented because of differences between two national movements. The relevance of the study is determined by the fact that the Tatar-Bashkir issue is still under discussion. Nowadays, Tatar national organizations think about the assimilation of a part of the Republic of Bashkortostan as well. One attempts to prove that the Bashkirs are not an independent ethnic group. It is assumed that the objective coverage of the problem will help ensure stability and sustainability in the relations between two contemporary national republics.
Attempts to falsify the history of the invasion of the Kuril Islands by the Soviet troops (in August 1945)
Authors: Pikalov Yury Vasilyevich ,   Far Eastern Law Institute of the Ministry of  Internal Affairs of the Russian Federation, Golovin Sergey Aleksandrovich ,   Blagoveshchensk State Pedagogical University
Published: January 2018

The falsification problem of Russian history in general and military history of Russia in particular is relevant due to the U.S. attempts to usurp the victory over terrorists in Syria and push Russia into the background in this regard. The most unacceptable fact is the falsification of the USSR contribution to the Second World War, including the war against militarist Japan in the Far East. Unfortunately, along with foreign authors distorting the history of the participation of Soviet troops in the war against militarist Japan, this trend is picked up by the domestic historians. They do not use scientific methods and technologies but apply manipulative techniques typical for the information wars. The paper considers the pseudohistorical methods and technologies of describing the invasion of the Kuril Islands by the Soviet troops in August 1945. These methods include the substitution of concepts designed for the ignorant readers. Besides, the pseudohistorians use emotional images which manipulate human con sciousness instead of the scientific facts that affect rational thinking. It results in the judgments on the unjustified cruelty of the Soviet troops to the Japanese units on the Kuril Islands, the violation of the terms of Japanese surrender by the Soviet commanders. The main purpose of such control over the historical consciousness of the Russians is to form an opinion on the illegal accession of the Kuril Islands to the Soviet Union following the Second World War. The paper emphasizes that it is necessary to be more involved in countering the false history of the USSR war against militarist Japan in August-September 1945.

Published: January 2018

The paper analyzes the concepts of ideology by L. Althusser, A. Gramsci, and G. Debord. The above-mentioned scientists reviewed the ideology not only as a tool for political ends but also as an effective strategy for deep cultural reforms involving the transformation of everyday practices, values, worldviews, and behavioral patterns. Based on three critical theories, the author reveals the main ways of building and spreading ideologies and identifies the main participants of ideological strategies. The research concludes that there is a considerable growth of the initiators of ideological concepts, and the ideological confrontation is more effective rather than physical conflicts and controversies. In modern culture, the overwhelming majority of civil society institutions and the business community form the ideologies aimed at constructing certain types of subjectivity.

The paper analyzes the emergence of travel media texts in Russian travel journals in the early 20th century as a consequence of implementing journey management function. The case study is the magazine “Trips Abroad” published in Saint Petersburg in 1907 and 1908. It has not been studied before. The magazine adhered to the ideology of outbound tourism. The research elaborates on the availability of the journal indicators showing the author’s intention to be a practical guide for his audience during the journey. The attributes of travel media texts that contribute to the achievement of the author’s goal are identified and described. The magazine “Trips Abroad” does not have any creolized texts which are compulsory for modern travel media content. According to the nature of the trip, the research distinguishes five main types of travel magazines in the early 20th century: non-tourist ones, outbound and inbound tourism magazines, domestic tourism magazines, universal travel magazines.
A comparative value analysis of state educational standards for primary schools in Russia and China
Authors: Qiu Manli ,   Far Eastern Federal University
Published: January 2018

The paper reviews vital, economic, aesthetic, political, social, and moral values of state educational standards for primary schools in Russia and China. Code for Students written in verse to learn it fast by students is an important part of Chinese Code of Primary School. The Russian Standard is created only for teachers and is not being studied by school students. A comparative analysis of these two standards reveal the similarities and differences in their value paradigms. The main difference concerns the political values. Thus, the Russian Standard in-volves the development of school students’ views on social justice, freedom, democratic values, whereas the Chinese Code does not include these categories. Love for the Communist Party of China is the first priority of this Code. The Chinese Code educates students in accordance with such princi-ples of Confucianism as harmony, humanity, and respect.
Creativity of V. Kandinsky – the gap between freedom and affirmative art
Authors: Malinina Nina Lvovna ,   Far Eastern Federal University
Published: January 2018

The artistic image is a categorial framework that allows one to analyze artistic creativity, artistic culture as well as the processes of creative culture. There is a theoretical problem of correlation between a creative product and its social significance. The relationships between the objectification of creativity and social reality have internal controversial unity. The artist expresses the values of his historical period, primarily humanistic and moral ones. The contradiction lies in the fact that art reflects values objectively and reveals them through artistic emotion but does not solve real problems. The avant-garde has evolved as a reaction to the changing social processes. The avant-garde movement destroyed the attitude to tradition, style as a dogma and an unbreakable rule. Avant-gardists were free to use the artistic means violating the rules of art. V. Kandinsky is a striking representative of both Russian and world avant-garde. He was able to demonstrate the visible social problems through something invisible in the artistic image. Artworks were created as a protest against unjust social reality, but in fact, it expressed negative emotions in an artistic manner and stopped the real protest. This was called an affirmative art. The avant-garde search for new artistic means led to the creation of an artistic image based on the activity of the viewer’s perception. The recipient was given the unprecedented freedom of interpretation. A work of art did not address social problems directly but gave a person the freedom to perceive the artistic image and co-create.
Perfectionist motives in social and philosophical thought
Authors:   North Caucasus State Academy of  Humanities and Technologies, Kushkhov Ramil Borisovich
Published: January 2018

The paper deals with the philosophical study on perfectionism in the history of the social and philosophical thought which is associated with the Aristotelian concept of teleology determining an appropriate nature of all processes including social ones. Perfectionist and optimistic elements are correlated with traditionalist and patriarchal ones. This comparison is treated as a substantialist, i.e. conservative, or ideological view on social reality. The above-mentioned standpoint is contrasted with the theory of social construction, utopian, or socially con-structed reflection. According to Aristotle, the God being an unmoved, prime mover of the universe is pure actuality and pure form. In his opinion, an individual should be realized in polis which is characterized by substantiality and is prior to the individual.

Published: January 2018

The paper discusses the results of the comprehensive ethnoarchaeological study on the average flow of the Zerkalnaya river valley in the South-Eastern Primorsky region near Bogopol settlement through the chronological range of the archaeological cultures, scientific essays of the 19th-century pathfinders and explorers, contemporary migrant ethnography. The authors suggest using the concept of the natural and historical system for the interdisciplinary study of the area. The paper provides a brief review of the history and the research results of Bogopol geo-archaeological complex. It is noted that the majority of the identified archaeological sites are multi-cultural and have artifacts related to different archaeological periods. The original field materials, ethnographic data which explain the migrant adaptation strategies in the area with the specific nature and climate are introduced. The authors conclude that because of intercultural collaboration and adaptation to the new natural environment, Bogopol residents start to lead a lifestyle which is typical for the rural polyethnic population of the Primorsky region.

Published: January 2018

Background

The aim of this retrospective study was to identify clinical, humoral and echocardiographic variables predicting rehospitalization and poor quality of life (QOL) in patients with reduced or mid-range ejection fraction heart failure.

Methods

From 2009 to 2012, 310 patients were admitted having signs and symptoms of heart failure with reduced ejection fraction. All the patients were followed by phone, calling the patients or the referring general practitioner. The Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used as the instrument to evaluate QOL: MLHFQ less than 24 is a good QOL, 24–45 is moderate QOL and more than 45 is poor QOL. The primary event was poor QOL and/or rehospitalization at 4 years.

Results

Seventy-nine patients died at median time of 21 months; 4-year survival was 72 ± 3%. Rehospitalization due to heart failure was recorded in 60 cases. Among 231 survivors, MLHFQ score was good in 99 (42%), moderate in 50 (21%) and poor in 88 (37%). Four-year freedom from death, poor QOL or rehospitalization was 51 ± 3%. Multivariable analysis identified the following risk factors: heart rate at discharge at least 70 bpm, ischemic heart disease, atrial fibrillation, hypercholesterolemia, chronic pulmonary disease, N-terminal pro brain natriuretic peptide at discharge, severe tricuspid regurgitation and mitral regurgitation more than moderate.

Conclusion

Clinical, laboratory and echocardiographic profile is crucial to predict long-term QOL of patients admitted for heart failure.
A Preclinical Course to Develop Clinical Reasoning Skills of First-year Medical Students
Authors: Johns Alan , Christensen Raymond
Published: January 2018

Background and Objectives: Clinical reasoning is developed sometime during medical school training.  When and how this knowledge is attained is less clear. This study looks at clinical reasoning development after initiation of a rural experiential course for first-year medical students at the University of Minnesota Medical School, Duluth (regional) Campus.

Methods: The Rural Medical Scholars Program course (RMSP) was developed to create a longitudinal rural family medicine experience for first and second-year students at the University of Minnesota Medical School Duluth. Sixty-three first year medical students participated in this required course and their clinical reasoning levels were measured using the Diagnostic Thinking Inventory (DTI).  The DTI was given to the medical students after one year of participation in the RMSP course. A previous cohort before the RMSP course was developed was used as a control. A literature search was used for comparison to other schools that measured the DTI in their students.

Results: Student diagnostic thinking performance as measured by the DTI after one year of the Rural Medical Scholars Program course significantly increased when compared to a previous cohort of first-year students who did not take the RMSP course. When compared to previously published DTI data, students after one year of RMSP had clinical reasoning levels of second through fourth-year students from other schools.

Conclusions: The addition of a rural experiential course with family medicine preceptors significantly increased clinical reasoning levels of first-year medical students.
