Giant Chondroid Syringoma of the Axilla
Authors: Hardisson David , Linares Maria D. , Nistal Manuel 
Published: July 2017

Background: Chondroid syringomas are benign uncommon tumours of controversial histogenesis that most often affect the head and neck region and usually measure > 3 cm in greatest dimension. Objective: To describe the clinical features, histology, and differential diagnosis of an unsually large axillary chondroid syringoma. Methods: A 64-year-old man presented with a painless, subcutaneous tumour measuring 8 × 7 × 6.5 cm on his right axilla, which had been growing slowly for several years. The tumour was completely excised under local anesthesia. No recurrence of the tumour has been observed 12 months after surgery. Results: Histological examination showed cords, nests, and tubuloglandular structures composed of well-differentiated tumour cells embedded in a hyalinized stroma with abundant chondroid matrix, and the diagnosis of chondroid syringoma was established. No features suggesting malignancy were observed. Conclusion: As this case shows, chondroid syringoma may reach a large size, and it should be included in the differential diagnosis of slowly growing solid nodules in the skin or subcutis.
Ultraviolet Radiation-Induced p53 Responses in the Epidermis are Differentiation-Dependent
Authors: Tron Victor A. , Li Gang , Ho Vincent , Trotter Martin J. 
Published: July 2017

Background: The tumour suppressor, p53, is recognized as a crucial molecule in regulating cellular responses to various DNA-damaging agents. Very early on in the development of nonmelanoma cancers p53 is mutated or lost, suggesting that p53 is crucial in protecting normal keratinocytes from the harmful effects of ultraviolet (UV) radiation. Objective: Using two mouse models, one with multiple copies of mutant p53 and the other a p53 “knockout,” our laboratory has examined a role for p53 in UV-induced DNA damage and determined if these effects are differentiation dependent. Conclusion: We outline in this review a proposed model reflecting differentiation-dependent p53 regulation of UV-induced responses in keratinocytes. After exposure to UV, basal keratinocytes repair damaged DNA, whereas differentiating keratinocytes undergo cell death, both processes are regulated by p53.

Introduction. Gym exercises have become more and more popular in the recent years. Thus, it is not surprising that this form of physical activity offered by University Sports Association has become a popular choice among the university students. However, to benefit from the workout, the exercises must be performed correctly. Application of excessive loads, number of repetitions, or poor technique can cause injury, which may lead to serious physical damage. Aim. The aims were to check the quality and organization of physical activities ogranized by University Sports Association in chosen universities of the Upper Silesia. The questions asked were:1. Is there a correlation between different universities and the health control among new students at the gym?2. Does the type of university correlate with the quality of the workout?3. Is there a correlation between the type of university and the duration of the strength training?Materials and Methods. 120 students were examined, among which there were 44 women aged 17 to 24 (x=20,8;SD= 1,8) and 76 man aged 17 to 28 (x=21,8; SD= 1,9). They were university students from the following Upper Silesian universities: ŚUM, AWF, UŚ and UE, who regularly practise gym exercises organized by Academic Sports Association. An original questionnaire was created for the purpose of this study. The questions concerned participation in the gym activities, choice of exercises in context of their health predispositions, presentation of the proper technique of exercises, information about synchronization exercises with breath and quality control of performed exercises without prior request of the students. Statistical analysis was performed by a program Statistica. Results. Analysis of variance (ANOVA) demonstrated a statistically significant relation between the type of university and the health control among new students at the gym (p=0,005). ŚUM is the university where the students are the most often controlled. There is no correlation between the type of university and the quality of the training (p=0,35). The duration of strength training is not correlated with the type of university. Students of AWF Katowice spend the most time at the gym, whereas students from ŚUM Katowice spend the least.Conclusion 1. Frequency of the health control among students starting classes at the gym depends on the type of university.2. The type of university does not affect the quality of the training.3. The duration of training does not depend on the type of university.

Przez uzyskanie prawa ochronnego na krajowy znak towarowy, rozumie się używanie znaku towarowego w sposób zarobkowy lub zawodowy na całym obszarze RP. Natomiast analogiczne uprawnienie wynikające z rejestracji wspólnotowego znaku towarowego, dotyczy stosowania znaku na terytorium całej Wspólnoty. Używanie znaku towarowego polega w szczególności na umieszczaniu tego znaku na towarach objętych prawem ochronnym lub ich opakowaniach, oferowaniu i wprowadzaniu tych towarów do obrotu, ich imporcie lub eksporcie, a także oferowaniu lub świadczeniu usług pod tym znakiem oraz posługiwaniu się takim znakiem w celu reklamy. W dobie wielkich pieniędzy, które bezsprzecznie rządzą dzisiejszym sportem, prawa ze znaków towarowych, obok praw do transmisji z wydarzeń sportowych, zyskują dla wszystkich sportowych jednostek organizacyjnych znaczenia kluczowego. Kluby, związki i federacje sportowe czerpią zyski z praw do znaków towarowych, głównie poprzez udzielanie przedsiębiorcom licencji na ich używanie. Proces ten najłatwiej zaobserwować przy okazji organizacji dużych wydarzeń sportowych.Jako cel badań niżej podpisany obrał wskazanie prawnych zasad zarządzania znakami towarowymi w sporcie, w obliczu ich ciągle rosnącego znaczenia. Publikacja obejmie prezentację sposób i zasady wykorzystywania zarejestrowanych już znaków sportowych przez sportowe jednostki organizacyjne, a także płynących stąd korzyści. Realizacja celu badawczego będzie dokonywana, przede wszystkim, przy zastosowaniu metody dogmatycznej. Analizie poddane zostaną akty prawa krajowego i unijnego. Podejmowana problematyka rodzi jednak konieczność uwzględnienia dorobku także innych nauk, zwłaszcza marketingu, biznesu i ekonomii. Wśród materiałów poddanych analizie, oprócz aktów prawa powszechnie wymienić należy także dane zgromadzonych w rejestrach znaków towarowych UP RP i OHIM. Za główny wniosek płynącym z niniejszego opracowania uznać należy konstatację, iż jakość w nowoczesnym sporcie przejawia się również, a w kwestii finansowej być może przede wszystkim, w jakości zarządzania znakami towarowymi.

Published: July 2017

BACKGROUNDDespite increasing healthcare costs, training on cost‐consciousness is lacking in graduate medical education (GME). Medical centers must consider how best to incorporate value‐based training into their GME curricula.OBJECTIVETo incorporate low‐value principles into an existing GME simulation exercise and assess incoming interns' recognition of low‐value care.METHODSChoosing Wisely™ lists were reviewed to identify 4 low‐value hazards to be embedded into a simulated hospital room in addition to the 8 patient safety hazards used previously. Interns were given 10 minutes to independently review a mock chart and list all hazards they identified in the simulation. Interns completed a short survey on their prior training in medical school and a follow‐up survey one month into internship. T tests used to compare identification of low‐value vs safety hazards and to associate performance with prior training.RESULTSThe mean percentage of hazards correctly identified was 50.4% (standard deviation [SD] 11.8%). Interns identified significantly fewer low‐value hazards (mean 19.2%, SD 18.6%) than safety hazards (mean 66.0%, SD 16.0%; P < .001). For example, while 96% of interns identified the hand hygiene hazard, only 6% identified the unnecessary blood transfusion and none identified the unnecessary stress ulcer prophylaxis. Interns who self‐reported as confident in their ability to identify hazards were not any more likely to correctly identify hazards than those who were not confident.CONCLUSIONSThe “Room of Horrors” simulation revealed poor awareness of low‐value care among interns. The simulation highlights a promising model for the prioritization and inclusion of value‐based experiential training in GME.

OBJECTIVETo characterize current use of communication technologies, including standard text messaging and secure mobile messaging applications, for patient care–related (PCR) communication.METHODSWe used a Society of Hospital Medicine database to conduct a national cross‐sectional survey of hospital‐based clinicians.RESULTSWe analyzed data from 620 survey respondents (adjusted response rate, 11.0%). Pagers were provided by hospitals to 495 (79.8%) of these clinicians, and 304 (49%) of the 620 reported they received PCR messages most commonly by pager. Use of standard text messaging for PCR communication was common, with 300 (52.9%) of 567 clinicians reporting receipt of standard text messages once or more per day. Overall, 21.5% (122/567) of respondents received standard text messages that included individually identifiable information, 41.3% (234/567) received messages that included some identifiable information (eg, patient initials), and 21.0% (119/567) received messages for urgent clinical issues at least once per day. About one‐fourth of respondents (26.6%, 146/549) reported their organization had implemented a secure messaging application that some clinicians were using, whereas few (7.3%, 40/549) reported their organization had implemented an application that most clinicians were using.DISCUSSIONPagers remain the technology most commonly used by hospital‐based clinicians, but a majority also use standard text messaging for PCR communication, and relatively few hospitals have fully implemented secure mobile messaging applications.CONCLUSIONThe wide range of technologies used suggests an evolution of methods to support communication among healthcare professionals.
Prominent Attributes Under Limited Attention
Authors: Zhu Yi , Dukes Anthony 
Published: July 2017

Evidence shows that marketers can direct consumers’ limited attention to specific product attributes by making them “prominent.” This research asks: How should firms decide which attribute to make prominent in competitive environments? A key feature of this setting is that consumers’ preferences are context-dependent and that a firm’s choice of an attribute affects the evaluation of all products in the category. We develop a model in which firms selectively promote one of two attributes (e.g., image or performance) before competing in price. We find when consumers evaluate both attributes, perceived differentiation within an attribute can become diluted; we call this the dilution effect. This implies that making the same attribute prominent can arise in equilibrium. Only if there is a sufficient quality advantage in an attribute do we find equilibria with firms making different attributes prominent. We also show how the dilution effect can be a disincentive for investments in quality improvements. Data and the online appendix are available at https://doi.org/10.1287/mksc.2017.1037 .
Non-invasive imaging in cardiology for the generalist
Authors: Davies Mark J , Newton James D 
Published: July 2017

In contrast to invasive techniques, the goal of non-invasive cardiac imaging is to identify or exclude heart disease in response to a patient's clinical history of cardiac localizing symptoms. Imaging also aims to establish the risk of an individual developing future heart disease with a view to preventing major cardiovascular events such as myocardial infarction. As well as a role in risk stratification, non-invasive cardiac imaging also helps with decision making for future medical and procedural interventions. This review outlines the non-invasive imaging modalities available to physicians to identify and risk stratify cardiovascular disease. It discusses the strengths of each imaging technique, in which circumstances it is most useful and its diagnostic accuracy.

The purpose of this study is to develop the "Bicycle Handicap Scale (BHS)" and to test the validity of the scale to demonstrate the obstacles bicyclists encounter. 292 bicycle riders cycling in Eskisehir and Ankara for various purposes for transportation or recr[1]eational purposes in their daily life were participated voluntarily. Explanatory and confirmatory factor analysis was performed in order to ensure the validity of the BEÖ structure. As a result of the exploratory factor analysis, a 5-dimensional structure was obtained on the scale. In the confirmatory factor analysis, five factorial structure was tested and it was determined that the obtained model was in accordance with the compliance criteria. According to this, BEÖ consists of 30 items consisting of 8 items in individual dimension, 5 items in law and regulation, 6 items in socio-cultural dimension, 7 items in physical and economic dimension and 4 items in infrastructure dimension. The internal consistency coefficient of the BEÖ was .92 for the scale, and between .89 and .73 for the subscales of the scale. As a result; It has been found that BEÖ is a useful measuring tool, developed to measure the attitudes of cyclists towards the obstacles encountered while riding a bicycle as a result of the validity and reliability studies conducted.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetBu çalışmanın amacı, bisiklet kullanıcılarının karşılaştıkları engelleri ortaya koyabilmek amacıyla “Bisiklet Engelleri Ölçeği’ni (BEÖ)” geliştirmek ve ölçeğin geçerlik güvenirlik çalışmasını yapmaktır.

The existence and distribution of plants on the earth with one of the most important elements of the natural environment are determined by the abiotic and biotic conditions. Changes that occur in natural conditions and human activities are generally creating a negative effect and many plant species are facing in danger of extinction. One of these conditions, climate is main factor that directly affects the lives of plants and determines the existence and distribution of vegetation as globally, regionally and locally.The greenhouse effect caused by human activities in the last century and the global climate change can have impacts on the existence and spatial changes of plants. In this context, the effects of temperature conditions as the main factor on vegetation are examined according to the certain temperature values and duration. Mean daily temperature values of meteorological stations, which have long term observation record, in the study area, were analyzed statistically. As a result, dates of start, dates of finish and number of days and temporal changes of vegetation period are determined in this period.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetDoğal ortamın en önemli unsurlarından olan bitkilerin varlığını ve yeryüzündeki dağılışını abiyotik ve biyotik koşullar belirlemektedir. Doğal koşullarda meydana gelen değişimler ve insan faaliyetleri, genellikle olumsuz etki yaratmakta ve birçok bitki türünün nesli tükenme tehlikesiyle karşı karşıya kalmaktadır.

AbstractConjugated polymers have been proposed as promising materials for scaffolds in tissue engineering applications. However, the restricted processability and biodegradability of conjugated polymers limit their use for biomedical applications. Here we synthesized a block-co-polymer of aniline tetramer and PCL (AT–PCL), and processed it into fibrous non-woven scaffolds by electrospinning. We showed that fibronectin (Fn) adhesion was dependent on the AT–PCL oxidative state, with a reduced Fn unfolding length on doped membranes. Furthermore, we demonstrated the cytocompatibility and potential of these membranes to support the growth and osteogenic differentiation of MC3T3-E1 cells over 21 days.
