Published: February 2018

Tubular adenoma of the breast is one of the most rare benign neoplasms, accounting for only 0.13% to 1.7% of all breast benign tumors. Little is known about this rare neoplasm as the current literature offers only some case reports or a few number of small series. The aim of our study is to provide some clinicopathologic features of the breast tubular adenoma. We retrospectively analyzed at our department of pathology all cases of breast tubular adenomas confirmed by immunohistochemistry over a period of 9 years (2009-2017). Nine cases of breast tubular adenoma have been recorded, with an average age of 31.44 years. Five tumors were located at the right side (55.55%), and most cases had suspicious aspects on imaging techniques (6 cases out of 9). The diagnosis has been made on 5 resected specimens (lumpectomy) and on 4 core needle biopsies. The tumor size ranged from 0.9 to 7 cm (mean size of 3.08 cm) and had well-circumscribed margins with elastic consistency. The histopathologic analysis showed a typical pattern of proliferating round and uniform tubules lined by regular epithelial cells surrounded by myoepithelial cells, packed in a small amount of stroma, highlighted by CD34 immunostaining. Tubular adenoma is a rare breast benign neoplasm of young premenopausal women. The radiologic aspects are often worrisome and only the histopathologic analysis can achieve the correct definitive diagnosis by excluding all potential differential diagnoses.

Authors: Aravind Amith , Prabhakaran Nair K , Joy M L
Published: February 2018

Biolubricants, though an answer to depleting mineral oil reserves and toxic pollutants seeping into the environment, have several drawbacks. They have a limited range of viscosities, poor low temperature properties, and reduced oxidative stability. Rubber seed oil, a nonedible oil extracted from rubber ( Hevea brasiliensis Muell. Arg) seeds, has been observed to serve as a good base stock for developing a novel biolubricant. This study aims at improving the properties of rubber seed oil, namely, its free fatty acid content, viscosity, cloud and pour point, tribological properties, and oxidative stability using suitable natural and synthetic additives to make it as good as commercial lubricants available in the market. A final formulation containing esterified rubber seed oil with (1% low-density polyethylene + 1.5% polypropylene as viscosity enhancers, 1.5% agarose to improve coefficient of friction, 1.5% butylated hydroxyl toluene as pour point depressant and (1% butylated hydroxyl anisole + 1.5% α-tocopherol + 1% ascorbic acid) as antioxidants has been found to have superior lubricant properties when compared to plain rubber seed oil. The biodegradability of the final formulated oil has also been studied.

Published: February 2018

Waterpipe tobacco smoking has grown in popularity among US college students and is associated with serious health risks. Much of the waterpipe tobacco smoking takes place in establishments such as “hookah bars” or in lounge settings. Web-based data platforms such as Yelp have demonstrated utility in locating these establishments but are prone to over- and underestimation. The purpose of this study was to optimize strategies for algorithmically estimating the prevalence of waterpipe tobacco smoking establishments. We conducted searches for potential waterpipe tobacco smoking establishments near highly residential US universities ( N = 41). Of 521 potential establishments, independent coders confirmed 257 as permitting waterpipe tobacco smoking. We compared four strategies for using Yelp metadata to estimate the number of confirmed waterpipe tobacco smoking establishments by location. An accuracy-weighted approach generated estimates that closely matched confirmed data without significant over- or underestimation. The use of algorithms such as these may dramatically improve the feasibility and efficacy of future research linking environmental data and health outcomes.

Objectives

The clinical condition of frailty is a common problem in the elderly population. However, the relationship between peripheral artery disease and frailty in hemodialysis patients remains unknown. The aim of this study was to identify the relationships between peripheral artery disease and frailty in Japanese chronic hemodialysis patients.

Methods

A total of 362 chronic hemodialysis patients who regularly visited six institutions were enrolled. To evaluate frailty, the modified Fried’s frailty phenotype adjusted for Japanese were used. Peripheral artery disease was defined as ankle-brachial index <0.9.

Results

Of 362 patients, 62 patients (17.1%) were categorized as peripheral artery disease group and 300 patients (82.9%) as Non-peripheral artery disease group. The prevalence of frailty in the peripheral artery disease group was significantly higher than in the Non-peripheral artery disease group (34% vs. 18%, P = 0.0103). Non-shunt side grip strength was significantly stronger in the Non-peripheral artery disease group (23.6 kg vs. 17.0 kg, P < 0.0001). Thigh circumferences were also significantly larger in the Non-peripheral artery disease group (41.7 cm vs. 39.7 cm, P = 0.0054). A multivariate logistic regression analysis demonstrated that the factors independently associated with peripheral artery disease were as follows: frailty (odds ratio = 2.06, 95% confidence interval 1.09–3.89) and myocardial infarction (odds ratio = 3.74, 95% confidence interval 2.05–6.83).

Conclusions

It is concluded that peripheral artery disease is closely associated with frailty in hemodialysis patients.
Three-dimensional analysis of deformities of the radius and ulna in congenital proximal radioulnar synostosis
Authors: Nakasone Motoko , Nakasone Satoshi , Kinjo Masaki , Murase Tsuyoshi , Kanaya Fuminori
Published: February 2018

We reconstructed three-dimensional images of radius and ulna in 38 forearms of 25 patients with congenital proximal radioulnar synostosis from their computed tomographic studies. We also analysed correlations between the deformities of radius and ulna and degrees of fixed pronation of these forearms. The average ulnar deviation, flexion and internal rotation deformities of the radius were 6°, 3° and 18°, respectively. The average radial deviation, extension and internal rotation deformities of the ulna were 3°, 4° and 30°, respectively. The flexion deformity of the radius and the internal rotation deformity of the radius and ulna were correlated significantly with degree of fixed pronation. We conclude that the patients with congenital proximal radioulnar synostosis have remarkable flexion deformity of the radius and internal rotation deformity of the radius and ulna, which might impede forearm rotation after corrective surgery in the proximal part of the forearm.
Off-label use of IV t-PA in patients with intracranial neoplasm and cavernoma
Authors: Schwarzbach Christopher Jan , Ebert Anne , Hennerici Michael G. , Neumaier-Probst Eva , Platten Michael , Fatar Marc
Published: February 2018

Background:

The safety of systemic thrombolysis in patients with intracranial tumor and cavernoma are unknown. So far evidence is limited to a number of case reports and few case series or unspecified data based on population-based analysis. Our aim was to comprehend the risk of systemic thrombolysis in these patients.

Methods:

Patients with additional evidence of intracranial tumor or cavernoma who received IV tissue plasminogen activator (t-PA) treatment at our comprehensive stroke center over a period of 7 years were identified in our stroke database and compared to the same number of matched control subjects without any evidence of intracranial tumor and cavernoma. Clinical history and imaging patterns before and after t-PA therapy were individually reviewed for each patient.

Results:

Thirty-four patients with additional evidence of meningioma (19/34), cavernoma (13/34) or malignant intracranial neoplasm (2/34) were identified. The incidence of secondary intracranial hemorrhage observed showed no difference between control subjects (9/34, 26%) and patients (6/34, 18%; p = 0.56). Symptomatic hemorrhage in patients with meningioma or cavernoma could not be observed. Likewise, the prevalence of stroke mimics showed no difference between patients (8/34, 24%) and control subjects (5/34, 15%; p = 0.54). However, both patients with malignant intracranial neoplasm presented with a stroke mimic and intracranial hemorrhage was observed in one of them.

Conclusions:

In compliance with existing evidence, treatment in patients with meningioma and cavernoma appears to be safe and reasonable, while the therapy should be avoided in patients with malignant intracranial neoplasm with blood–brain barrier disruption.
Open-label pilot for treatment targeting gut dysbiosis in myalgic encephalomyelitis/chronic fatigue syndrome: neuropsychological symptoms and sex comparisons
Authors: Wallis Amy , Ball Michelle , Butt Henry , Lewis Donald P. , McKechnie Sandra , Paull Phillip , Jaa-Kwee Amber , Bruck Dorothy
Published: February 2018

Background

Preliminary evidence suggests that the enteric microbiota may play a role in the expression of neurological symptoms in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Overlapping symptoms with the acute presentation ofd-lactic acidosis has prompted the use of antibiotic treatment to target the overgrowth of species within theStreptococcusgenus found in commensal enteric microbiota as a possible treatment for neurological symptoms in ME/CFS.

Methods

An open-label, repeated measures design was used to examine treatment efficacy and enable sex comparisons. Participants included 44 adult ME/CFS patients (27 females) from one specialist medical clinic withStreptococcusviable counts above 3.00 × 105 cfu/g (wet weight of faeces) and with a count greater than 5% of the total count of aerobic microorganisms. The 4-week treatment protocol included alternate weeks of Erythromycin (400 mg of erythromycin as ethyl succinate salt) twice daily and probiotic (d-lactate free multistrain probiotic, 5 × 1010cfu twice daily). 2 × 2 repeated measures ANOVAs were used to assess sex-time interactions and effects across pre- and post-intervention for microbial, lactate and clinical outcomes. Ancillary non-parametric correlations were conducted to examine interactions between change in microbiota and clinical outcomes.

Results

Large treatment effects were observed for the intention-to-treat sample with a reduction inStreptococcusviable count and improvement on several clinical outcomes including total symptoms, some sleep (less awakenings, greater efficiency and quality) and cognitive symptoms (attention, processing speed, cognitive flexibility, story memory and verbal fluency). Mood, fatigue and urined:llactate ratio remained similar across time. Ancillary results infer that shifts in microbiota were associated with more of the variance in clinical changes for males compared with females.

Conclusions

Results support the notion that specific microorganisms interact with some ME/CFS symptoms and offer promise for the therapeutic potential of targeting gut dysbiosis in this population.Streptococcusspp. are not the primary or sole producers ofd-lactate. Further investigation of lactate concentrations are needed to elucidate any role ofd-lactate in this population. Concurrent microbial shifts that may be associated with clinical improvement (i.e., increasedBacteroidesandBifidobacteriumor decreasedClostridiumin males) invite enquiry into alternative strategies for individualised treatment.

Conservative treatment of postoperative chylothorax: a case report
Authors: Wagh Sachinkumar , Deshmukh Sanjay , Ankolikar Shrikant
Published: February 2018

Background

Chylothorax is a well-documented complication of thoracic trauma and is associated with high rates of morbidity and mortality. Treatment for chylothorax includes conservative measures (total parenteral nutrition, pleural drainage, and pleurodesis) and surgery (thoracic duct ligation).

Case presentation

We present the case of a 65-year-old man who developed chylothorax after an elective surgical procedure. In this report conservative treatment aims to reduce chyle flow, to drain the pleural cavity in an effective manner, and to prevent chronic sequelae. Optimal conservative treatment, started immediately upon diagnosis, effectively reduces the need for reoperation and long-term hospitalization, and it might prevent further sequelae of chylothorax.

Conclusions

The chylothorax was successfully treated conservatively, which may reduce the need for reoperation.
Handwritten Indic Script Recognition Based on the Dempster–Shafer Theory of Evidence
Authors: Mukhopadhyay Anirban , Singh Pawan Kumar , Sarkar Ram , Nasipuri Mita
Published: February 2018

In a multilingual country like India, script recognition is an important pre-processing footstep necessary for feeding any document to an optical character recognition (OCR) engine, which is, in general, script specific. The present work evaluates the performance of an ensemble of two MLP (multi-layer perceptron) classifiers, each trained on different feature sets. Here, two complementary sets of features, namely, gray-level co-occurrence matrix (GLCM) and Gabor wavelets transform coefficients are extracted from each of the handwritten text-line and word images written in 12 official scripts used in Indian subcontinent, which are then fed into an individual classifier. In order to improve the overall recognition rate, a powerful combination approach based on the Dempster–Shafer (DS) theory is finally employed to fuse the decisions of two MLP classifiers. The performance of the combined decision is compared with those of the individual classifiers, and it is noted that a significant improvement in recognition accuracy (about 4% for text-line data and 6% for word level data) has been achieved by the proposed methodology.
Afterword: Theorizing (im)politeness
Authors: Haugh Michael
Published: February 2018

The shift to a middle ground between classic and discursive approaches to politeness has opened
up space for the proliferation of various different theoretical accounts of (im)politeness. While this diversity
can lead to different insights into the same dataset, as we have seen in this special issue, it does beg the
question of whether the field of (im)politeness research remains a coherent enterprise. After pointing
out that different theories of (im)politeness inevitably not only afford but also constrain what we observe
and the explanations that can be developed to account for those observations, I suggest that in light of
the increasing proliferation of theoretical approaches in the field, a greater focus on metatheorization is
in order. After briefly discussing some of the key questions such a metatheoretical discussion should
address, I conclude that metatheorizing enables us to systematically examine what different theories
of (im)politeness bring to the field, thereby also drawing attention to what areas appear to be in particular
need of further theoretical development and empirical study.

Authors: Kocak Ayse , Harmancı Duygu , Birlik Merih , Sarıoglu Sulen , Yılmaz Osman , Cavdar Zahide , Guner Gul
Published: February 2018

Objective

The aim of the present study was to evaluate the potential protective effects of epigallocatechin-3-gallate (EGCG) on fibrosis in bleomycin induced scleroderma model.

Materials and methods

Thirty-two healthy female Balb-c mice with the average body weight of 22±5 g were used in this study. The mice were randomly divided into four groups as control (n=8), Bleomycin (n=8), Bleomycin+EGCG (n=8) and EGCG (n=8). Skin tissue samples were collected to quantify matrix metalloproteinases (MMP-1, MMP-8, MMP-13), p-SMAD 2/3 and SMAD 2/3 in protein homogenates by western blotting. TGF-β1 expression was determined by real-time PCR. Immunohistopathological and histopathological examinations of skin tissues were also done.

Results

When measured with Masson Trichrome, EGCG treatment was found to decrease fibrosis in connective tissue compared to the BLM injected control. EGCG was decreased dermal fibrosis. Bleomycin+EGCG group showed a significant reduction in fibrosis at the dermal surface area using hematoxylin measurements compared with the BLM group. MMP-1, MMP-8 protein levels were increased and p-SMAD 2/3 protein level was decreased. TGF-β mRNA expression was decreased in the EGCG+BLM group compared with the BLM group.

Conclusion

These results suggest an antifibrotic role for EGCG.

Authors: Celik Saadet , Seyrekel Tuncay , Arpa Medeni
Published: February 2018

Objective

Sample rejection is an important step in the laboratory related with the patient safety. Periodical analysis of rejected samples is necessary to define the causes of rejection and follow-up the requirements for staff training. In this study, we aimed to put forth the efficiency of trainings by analyzing the amount of rejected samples in Yozgat State Hospital.

Materials and methods

Taken from laboratory information system (LIS), rejected sample statistics related to 8 month-data before training was compared with 8-month data after training between 07.2015 and 10.2016 are examined. These datas were compared in itself and to each other. All statistical analyses were performed using the SPSS (V15).

Results

Before training, the average number of patients for the analysis included months was 34,733 [standard deviation (SD)±4031], the number of rejected samples was 397.7 (SD±85.3) and the average rejection percentage was 1.13 (min-max: 1–1.29). The average number of patients for the after training months was 39,426 (SD±4779), the number of rejected samples was 343.2 (SD±57.7) and the average rejection percentage was 0.87 (min-max: 0.62–0.98), Rejected sample rates were significantly lower interms of statistics in the after-training group (p=0.0001).

Conclusion

Staff training takes a very important place preventing these mistakes. As it can be seen in our study, training helps decreasing rejection rates. It is suggested to schedule more trainings in order to decrease the rates to lower degrees.

Published: February 2018

A series of γ-MnO2-Ce/MMT catalyst materials synthesized by homogeneous precipitation method was investigated for the selective catalytic reduction (SCR) of NOx with NH3. X-ray diffraction and specific surface areas were utilized for micro structure and layer spacing investigation. And NH3-TPD, Pyridoxine IR, H2-TPR and XPS were used to investigate Brønsted acid and Lewis acid, redox properties, atomic concentrations and element chemical state for as-prepared catalysts. The results showed that the γ-MnO2-Ce/MMT had superior NOx conversion compared to the bulk particles, among which 6 wt.% γ-MnO2-Ce/MMT displayed the best deNOx of 95.3% for the low temperature selective catalytic reduction of NOx with NH3 (NH3-SCR) under the GHSV of 25,000 h−1, therefore it is a promising catalyst for low temperature NH3-SCR.
La contribución de la extensión universitaria al desarrollo humano y a la expansión de las capacidades. Análisis de proyectos de la Universidad Nacional de Costa Rica
Authors: Zlateva Peneva Pepa
Published: February 2018

El presente trabajo tiene como objetivo principal determinar los aportes al desarrollo humano (DH) y la expansión de las capacidades de la extensión universitaria que realiza la Universidad Nacional de Costa Rica (UNA). Se analiza la coherencia entre la extensión universitaria y los valores del enfoque del DH: bienestar, participación, equidad y sostenibilidad (Boni y Gasper, 2011). Se busca también la contribución al DH en términos de capacidades generadas en la población beneficiaria de tres proyectos universitarios a través de las valoraciones de los responsables de los proyectos y las personas locales involucradas. Hemos logrado un acercamiento a la tradición extensionista latinoamericana, y costarricense en particular, por medio de los programas, proyectos y actividades extensionistas de la UNA. Presentamos el enfoque del desarrollo humano y capacidades (EDHC) desde las perspectivas de Sen y Nussbaum y las visiones de una serie de autores sobre la contribución del enfoque a la calidad de la universidad. El método de análisis es el estudio de casos; mediante técnicas cualitativas se profundiza en las valoraciones de las personas a través de entrevistas semiestructuradas y observación participante, además de la revisión documental. Se logró evidenciar la presencia de los valores del DH en la filosofía y las actividades extensionistas; se obtuvo una lista de capacidades expandidas por medio de las políticas universitarias y de los factores de conversión (características personales, particularidades ambientales de las localidades, la presencia de las instituciones, entre otras), fundamentales para la expansión de las libertades. A pesar de algunas debilidades y desafíos, encontramos altamente prioritario que las universidades latinoamericanas mantengan el acompañamiento a la población local, como un factor determinante para el DH de las comunidades deprimidas.

In situ testing of barrette foundations for a high retaining wall in molasse rock
Authors: Rabaiotti C. , Malecki C.
Published: February 2018

Barrettes are common foundations for high-rise buildings, especially because of their high bearing capacity, for vertical as well as for lateral loads. In this paper, it is shown how these were adopted and tested for anchoring a 27 m high retaining wall in rock on a slope located in the centre of Zurich. The monolithic 10 × 1 × 25 m deep barrettes, excavated and built in layered rock (Upper Freshwater Molasse), are also intended to stabilise the slope. The main contribution to their bearing capacity is given by the contact strength between the reinforced concrete and the rock. Two full-scale pull-out tests, instrumented by distributed fibre-optical measurements, are carried out to investigate the contact strength between rock and reinforced concrete. The results show that dilatancy at the contact caused by the irregular excavated surface has a strong influence on the bearing capacity. Additionally, the distributed fibre-optic instrumentation allowed progressive crack propagation of the reinforced concrete in the barrettes to be detected during the test. Inverse analysis of the rock and concrete tensile properties are obtained within a finite-element calculation, which takes into account the non-linear properties of the reinforced concrete and the rock.
The Effect of the LMX of Hotel Employees on Organizational Commitment and Job Performance: Focusing on the Moderating Effect of AB Personality Types
Authors:   The Tourism Sciences Society Of Korea, Han Deok-Soo , Lee Hyung-Ryong
Published: February 2018

The purpose of this survey is to identify the effect of LMX on organizational commitment through an empirical analysis. This will be done according to the types of character of each employee and according to their individual organizational focus and work performance. For this analysis, employees who had been working in 5 stars hotel for more than a year in the hospitality field throughout Seoul and Incheon were surveyed. 350 questionnaires were distributed from the 12th of September to the 30th of September 2016,and from these 302 samples were finally used for empirical analysis. The results showed that the two sub-factors of emotional trust and transactional relationship in LMX both had an impact that was positively significant (+). Transactional trust relations all influenced attention positively. (+) Job performance and organizational commitment were found to have a positive impact on attention (+) to job performance. Furthermore, AB personality plays a role in the emotional relationship of mutual trust that then impacts organizational commitment. However, transactional does not influence the level of organizational commitment. Finally, the emotional relationship of mutual trust had a significant regulating role for AB personality types, whereas, transactional trust relationships did not influence AB personality types.
An Exploration of the Causal Loop Structure and Policy Leverage in the Tourism Gentrification Phenomenon: With a Focus on Bukchon Area
Authors:   The Tourism Sciences Society Of Korea, An Ji-Hyun , Kim Nam-Jo
Published: February 2018

This study began after sensing a problem being caused by tourism gentrification in the Bukchon area. The purpose of this study was therefore to understand the causal loop structure of gentrification taking place in Bukchon tourist attraction. The Structure and cause of this tourism gentrification phenomenon indicates that this could draw causal feedback structures which: 1) Limit the tourism carrying capacity, 2) Polarize wealth caused by commercialization and spatial change, and 3) Manage resources and the tragedy of the commons. Policy leverages developed from the structural causes of tourism gentrification were as follows: First, the limits of tourism carrying capacity can be improved by enhancing the physical capacity and social capacity in order that a more fundamental alternative might fully calculate the volume of visitors that tour courses could accommodate. Secondly, the polarization of wealth caused by commercialization and spatial change is a viciously structured cycle in which two positive feedback loops are skewed between two extremes. Therefore, it is recommended that the Seoul Metropolitan Government should expand its current policies restricting new large franchises in Bukchon and reorganize the Bukchon tourist district reviewing the Commercial Building Lease Protection Act as soon as possible. In addition, a city-wide awareness of the gentrification issue must be undertaken. Third, in terms of resource management and the tragedy of the commons, this study invoked a study by Ostrom to suggest that communities need to voluntarily and autonomously manage their own resources. The study argues that sustainability in tourist attractions must take place gradually with voluntary participation from local residents and collaboration between many different fields.

Banking Industry Regulation and Strategic Action Fields: a research agenda for Economic Sociology.
Authors: Santana Turégano Manuel Ángel
Published: February 2018

This paper examines the evolution of the regulation of the banking industry in the EU after the global financial crisis of 2008. It proposes to analyze the sector as a strategic action field, embedded in a web of fields and where participants differ in their power and influence. The analysis is focused in two policies implemented under the new European regulation, the limitation of the variable remuneration and the introduction of diversity quotas. It follows the policy making mechanism, from the scientific discussion about whether these measures improve the performance of organizations to the adoption of policies that close all controversies in a black box, following ideas developed in the Social Studies of Science (SSS). This inquiry, albeit modest, suggest that a deeper understanding of the regulation of the banking industry could be gained following an approach that combines Strategic Action Fields Theory and Social Studies of Science.

Cotidianidad y Señales Visuales Espontáneas como Referentes de Creación Artística en la Era Global.
Authors: Cova Massimo
Published: February 2018

A good part of the shapes and content of contemporary artistic productiontakes aspects of daily life related to the complex consequences of economicand cultural globalization as its references of creation, along with thedevelopment and expansion of new technologies. It establishes a reflection oncontemporary art’s ability to translate and reconfigure several individual orgroup cultural values emanating from visual signals present in everydayenvironments and generated by the very movements that people make in theirinteractions. Some projects and models of contemporary artistic creation areshown and related that adopt spontaneous visual signals as formal andconceptual references, ephemeral and transitory outlines produced by humanbehaviours and which can be representative of ways of living and thinking inthe era of globalization. Works by diverse artists not conventionally linked bytheme, style or genre but which formalize and reconfigure visual cues notnormally considered inherent to the field of art.
Influence of oil pollution on the microbiocenosis of soils adjacent to the oil storage
Authors: Zhuravleva Anna S. , Labutova Natal'ya M. , Andronov Evgeniy E.
Published: February 2018

The aim of the work was an investigation of the effect of hydrocarbons on bacterial and fungal cenoses of sod-podzolic soils on the territory adjacent to the oil storage in the village Malye Kolpany, Leningrad Region. NGS methods were used to analyze the taxonomic composition and structure of the bacteriocenosis and the method of direct microscopy by Demkina-Mirchink to determine the length of the fungal mycelium and the number of spores. Taxonomic and structural changes in the bacterial community led to the dominance of genera containing numerous species-oil destructors. It is established that the main role in the decomposition of oil in the investigated territorybelongs to prokaryotes related to the genera Pseudoxanthomonas, Methylobacterium and Nocardioides. Mycocenosis showed high sensitivity and low adaptability to oil contamination.

Background: A first quality of life (QOL) study among Maltese adults with congenital heart disease (ACHD) in 2016 found no significant differences when compared to the general population.  The aims of the present study were to (1) compare QOL between Maltese and other European ACHD patients and (2) investigate medical predictors (i.e. number of surgical/non-surgical interventions, heart failure, arrhythmias, pacemaker/implantable cardioverter-defibrillator, cardiac hospitalisation during preceding year, follow-up frequency, other medical conditions, mood/anxiety/psychiatric disorders) of QOL in Maltese patients.Methods: Data collected during “Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease–International Study” (APPROACH-IS) was used.  QOL was measured using linear analog scale (LAS) and Satisfaction With Life Scale (SWLS).  QOL in 109 Maltese and 1510 European participants was compared.  Multivariable logistic regression was used to test the predictive value of medical factors on QOL in Maltese patients.Results: There were no significant differences in QOL between the two cohorts [mean LAS Malta 80.51 (95% CI 77.96,83.07) vs. European 79.43 (95% CI 78.65,80.21) (p=0.776); mean SWLS Malta 26.00 (95% CI 24.94,27.06) vs. European 26.26 (95% CI 25.95,26.57) (p=0.288)] and no significant differences when cohorts were divided by gender and age.  Only a mood/anxiety/other psychiatric disorder significantly predicted poorer QOL on both scales in Maltese patients (LAS (ß=-.389, p<0.001), SWLS (ß=-.352, p=0.001)). Conclusions: Maltese ACHD patients have a good QOL comparable to that of European counterparts.  Mood, anxiety and other psychiatric disorders can negatively impact Maltese patients’ QOL.  Better access to clinical psychology services should be ensured.

Fighting bacterial resistance: approaches, challenges, and opportunities in the search for new antibiotics.Part 1. Antibiotics used in clinical practice: mechanisms of action and the development of bacterial resistance
Authors: Zhivich Alexander
Published: February 2018

Hundreds of thousands of people are dying every year in the world from infections caused by drug resistant bacteria. Antibiotic resistance is a rapidly increasing problem mostly as a result of the worldwide overuse and misuse of antibiotics for conditions that do not require them. The rapid spread of antibiotic resistance in bacteria makes it necessary to intensify the development of new antibiotics and new methods to combat drug resistant bacteria. The goal of this publication is to review the approaches to finding new antibiotics that are active against drug resistant bacteria. The first part of this review is focused on an analysis of the mechanisms of action of antibiotics that are used in clinical practice as well as the mechanisms of bacterial resistance. The molecular structure and modes of action of these antibiotics are reviewed with examples of detailed mechanisms of drugs interaction with the targets in bacteria. General and specific mechanisms of bacterial resistance to these antibiotics are described. Examples of new antibiotics development active against the drug resistant bacteria are presented.
Efficient Market Hypothesis And Stock Market Anomalies: Empirical Evidence In Four European Countries
Authors: Rossi Matteo , Gunardi Ardi
Published: February 2018

The stock market efficiency is the idea that equity prices of listed companies reveal all the data regarding the company value (Fama, 1965). In this way, there isn’t possible to make additional returns. However, evidence against the Efficient Market Hypothesis is growing. Researchers studied Calendar Anomalies (CAs) that characterised financial markets. These CAs contradict the efficient hypothesis. This research studies some of the most important market anomalies in France, Germany, Italy and Spain stock exchange indexes in the first decade of new millennium (2001-2010). In this study, to verify the distribution of the returns and their auto correlation, we use statistical methods: the GARCH model and the OLS regression. The analysis doesn’t show strong proof of comprehensive Calendar Anomalies. Some of these effects are country-specific. Furthermore, these country-anomalies are instable in the first decade of new millennium, and this result demonstrates some doubt on the significance of CAs.
