Effects of Inhibition of Interleukin-6 Signalling on Insulin Sensitivity and Lipoprotein (A) Levels in Human Subjects with Rheumatoid Diseases
Interleukin-6 (IL-6) is a pro-inflammatory cytokine that has been found to be increased in type 2 diabetic subjects. However, it still remains unclear if these elevated IL-6 levels are co-incidental or if this cytokine is causally related to the development of insulin resistance and type 2 diabetes in humans. Therefore, in the present study we examined insulin sensitivity, serum adipokine levels and lipid parameters in human subjects before and after treatment with the IL-6 receptor antibody Tocilizumab.11 non-diabetic patients with rheumatoid disease were included in the study. HOMA-IR was calculated and serum levels for leptin, adiponectin, triglycerides, LDL-cholesterol, HDL-cholesterol and lipoprotein (a) (Lp (a)) were measured before as well as one and three months after Tocilizumab treatment. The HOMA index for insulin resistance decreased significantly. While leptin concentrations were not altered by inhibition of IL-6 signalling, adiponectin concentrations significantly increased. Thus the leptin to adiponectin ratio, a novel marker for insulin resistance, exhibited a significant decrease. Serum triglycerides, LDL-cholesterol and HDL-cholesterol tended to be increased whereas Lp (a) levels significantly decreased.Inhibition of IL-6 signalling improves insulin sensitivity in humans with immunological disease suggesting that elevated IL-6 levels in type 2 diabetic subjects might be causally involved in the pathogenesis of insulin resistance. Furthermore, our data indicate that inhibition of IL-6 signalling decreases Lp (a) serum levels, which might reduce the cardiovascular risk of human subjects
The management of acute venous thromboembolism in clinical practice. Results from the European PREFER in VTE Registry
Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in Europe. Data from real-world registries are necessary, as clinical trials do not represent the full spectrum of VTE patients seen in clinical practice. We aimed to document the epidemiology, management and outcomes of VTE using data from a large, observational database. PREFER in VTE was an international, non-interventional disease registry conducted between January 2013 and July 2015 in primary and secondary care across seven European countries. Consecutive patients with acute VTE were documented and followed up over 12 months. PREFER in VTE included 3,455 patients with a mean age of 60.8 ± 17.0 years. Overall, 53.0 % were male. The majority of patients were assessed in the hospital setting as inpatients or outpatients (78.5 %). The diagnosis was deep-vein thrombosis (DVT) in 59.5 % and pulmonary embolism (PE) in 40.5 %. The most common comorbidities were the various types of cardiovascular disease (excluding hypertension; 45.5 %), hypertension (42.3 %) and dyslipidaemia (21.1 %). Following the index VTE, a large proportion of patients received initial therapy with heparin (73.2 %), almost half received a vitamin K antagonist (48.7 %) and nearly a quarter received a DOAC (24.5 %). Almost a quarter of all presentations were for recurrent VTE, with >80 % of previous episodes having occurred more than 12 months prior to baseline. In conclusion, PREFER in VTE has provided contemporary insights into VTE patients and their real-world management, including their baseline characteristics, risk factors, disease history, symptoms and signs, initial therapy and outcomes
EFEKTIVITAS PENGAWASAN UNIT KERJA ANTI FRAUD PADA BANK MUAMALAT INDONESIA
Perkembangan perbankan syari‟ah di Indonesia demikian pesat yang
ditandai dengan berdirinya Bank Muamalat Indonesia. Perkembangan ini
berimplikasi pada besarnya tantangan perbankan syari‟ah di Indonesia terutama
dalam mempertahankan identitasnya sebagai perusahaan yang bergerak
berlandaskan prinsip-prinsip syari‟ah. Sejak berdirinya perbankan
syariah,berbagai kontroversi muncul dari masyarakat, masalah yang paling
banyak disorot adalah pelekatan label syariah pada institusi keuangan Islam yang
masih dianggap belum layak. Keraguan masyarakat tersebut seolah terjawab
dengan munculnya kasus yang cukup menggemparkan yakni kasus fraud (tindak
kecurangan) yang terjadi di lembaga syariah.
Bank Muamalat Indonesia merupakan bank syari‟ah pertama yang muncul
dengan gagasan bank murni syari‟ah. Akan tetapi, bank Muamalat Indonesia juga
tak luput dari kasus fraud yang dilakukan oleh karyawan bank tersebut.
Berdasarkan Laporan Tahunan BMI menyebutkan bahwa telah terjadi
peningkatan kasus fraud dari tahun sebelumnya yang berjumlah 18 kasus menjadi
82 kasus pada tahun 2016. Padahal perusahaan yang menggunakan identitas
syariah seharusnya dapat lebih meminimalisir bahkan meniadakan resiko
terjadinya kasus fraud dengan adanya internal control perusahaan. Dari latar
belakang tersebut, peneliti berusaha mendalami peran pengawasan Unit Kerja
Anti Fraud dalam fraud preventive pada Bank Muamalat Indonesia. Penelitian ini
merupakan penelitin pustaka yang bersifat deskriptif analisis dengan pendekatan
kualitatif. Adapun sumber bahan hukum primer yang dipakai yaitu berdasarkan
Laporan Tahunan Bank Muamalat Indonesia Tahun 2016. Sedangkan sumber
bahan hukum sekunder berupa buku-buku, jurnal,karya ilmiah, artikel, terkait
dengan strategi anti fraud perbankan syariah.
Dari hasil penelitian dikemukakan bahwa peningkatan kasus fraud yang
terjadi pada Bank Muamalat Indonesia disebabkan kurang efektifnya pengawasan
Unit Kerja Anti Fraud. Hal ini dikarenakan kegiatan yang dilakukan selama tahun
2016 belum menujukkan adanya usaha preventif terhadap kasus fraud. Sedangkan
pencegahan merupakan pilar penting dalam keefektivan sebuah pengawasan.
Tujuan perusahaan dalam mencegah fraud dapat tercapai, jika fungsi pengawasan
dilakukan sebelum terjadinya penyimpangan-penyimpangan sehingga lebih
bersifat mencegah (prefentive control). Oleh karena itu, keefektivan pengawasan
Unit Kerja Anti Fraud diharapkan dapat meminimalisir tindak kecurangan demi
mewujudkan perusahaan yang patuh terhadap ketentuan syariah sesuai dengan
identitas perusahaan.

Usaha pencegahan terjadinya kasus pada Bank Muamalat Indonesia
diharapkan dapat menjadi bukti terlaksananya tatakelola perusahaan (Good
Corporate Governance) pada Bank Syari‟ah dengan baik. Hal ini berdasarkan
dalam dalam perbankan syariah dikenal adanya prinsip-prinsip syariah yang
mendukung bagi terlaksananya prinsip GCG yakni keharusan bagi subjek hukum
termasuk bank untuk menerapkan prinsip kejujuran (shiddiq), edukasi kepada
masyarakat (tabligh), kepercayaan (amanah), dan pengelolaan secara profesional

Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases
The production of peroxide and superoxide is an inevitable consequence of
aerobic metabolism, and while these particular "reactive oxygen species" (ROSs)
can exhibit a number of biological effects, they are not of themselves
excessively reactive and thus they are not especially damaging at physiological
concentrations. However, their reactions with poorly liganded iron species can
lead to the catalytic production of the very reactive and dangerous hydroxyl
radical, which is exceptionally damaging, and a major cause of chronic
inflammation. We review the considerable and wide-ranging evidence for the
involvement of this combination of (su)peroxide and poorly liganded iron in a
large number of physiological and indeed pathological processes and
inflammatory disorders, especially those involving the progressive degradation
of cellular and organismal performance. These diseases share a great many
similarities and thus might be considered to have a common cause (i.e.
iron-catalysed free radical and especially hydroxyl radical generation). The
studies reviewed include those focused on a series of cardiovascular, metabolic
and neurological diseases, where iron can be found at the sites of plaques and
lesions, as well as studies showing the significance of iron to aging and
longevity. The effective chelation of iron by natural or synthetic ligands is
thus of major physiological (and potentially therapeutic) importance. As
systems properties, we need to recognise that physiological observables have
multiple molecular causes, and studying them in isolation leads to inconsistent
patterns of apparent causality when it is the simultaneous combination of
multiple factors that is responsible. This explains, for instance, the
decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference
Observation of the Gamma-Ray Binary HESS J0632+057 with the HESS, MAGIC, and VERITAS Telescopes
The results of gamma-ray observations of the binary system HESS J0632 + 057 collected during 450 hr over 15 yr, between 2004 and 2019, are presented. Data taken with the atmospheric Cherenkov telescopes H.E.S.S., MAGIC, and VERITAS at energies above 350 GeV were used together with observations at X-ray energies obtained with Swift-XRT, Chandra, XMM-Newton, NuSTAR, and Suzaku. Some of these observations were accompanied by measurements of the H alpha emission line. A significant detection of the modulation of the very high-energy gamma-ray fluxes with a period of 316.7 +/- 4.4 days is reported, consistent with the period of 317.3 +/- 0.7 days obtained with a refined analysis of X-ray data. The analysis of data from four orbital cycles with dense observational coverage reveals short-timescale variability, with flux-decay timescales of less than 20 days at very high energies. Flux variations observed over a timescale of several years indicate orbit-to-orbit variability. The analysis confirms the previously reported correlation of X-ray and gamma-ray emission from the system at very high significance, but cannot find any correlation of optical H alpha parameters with fluxes at X-ray or gamma-ray energies in simultaneous observations. The key finding is that the emission of HESS J0632 + 057 in the X-ray and gamma-ray energy bands is highly variable on different timescales. The ratio of gamma-ray to X-ray flux shows the equality or even dominance of the gamma-ray energy range. This wealth of new data is interpreted taking into account the insufficient knowledge of the ephemeris of the system, and discussed in the context of results reported on other gamma-ray binary systems

The relationship between emotion regulation, emotion knowledge and adjustment in preschoolers: A mediation model.
The study explored the total, direct and indirect effects of emotion knowledge on adjustment in preschoolers ans examined whether emotion regulation mediated the relationships between emotion knowledge and adjustment (social competence, and behavioral difficulties, such as anxiety–withdrawal and anger–aggression). Two hundred forty children (118 boys and 122 girls) from 3 to 5 years of age (mean age = 4.23, SD = .80) were administered a vocabulary test to check their verbal ability and a measure of emotion knowledge. Teachers filled out two questionnaires about children’s regulation and adjustment variables. A mediation model was tested combined with an assessment of the indirect effects to evaluate whether emotion knowledge may exert an influence on adjustment through the intervention of emotion regulation. Results showed that all conditions for full mediation were met for social competence and anxiety–withdrawal, confirming the mediation role of emotion regulation in the relationship between emotion knowledge and these variables.
Moreover, results indicated that emotion knowledge and anger–aggression were not directly associated as they would be in case of full or partial mediation, but they were however indirectly related through a significant linking with emotion regulation. Findings may have potential implications for prevention and intervention programs in family and school contexts, suggesting how early childhood programs targeting emotion knowledge may be especially beneficial to promote social competence and prevent behavioral problems, above all if they include other emotion-related competences, such as emotion regulation, that may be considered the linking mechanism through which emotion knowledge exerts an influence on adjustment

Estratégia profissional e mimetismo empresarial: os planos de saúde odontológicos no Brasil Professional strategy and institutional isomorphism: the dental health insurance industry in Brazil
O artigo analisa o modelo organizacional das empresas de planos de saúde odontológicos das modalidades de cooperativas de profissionais e a odontologia de grupo para compreender a dinâmica da oferta de serviços odontológicos no país. Adotou-se como referência a formulação institucionalista de Di Maggio e Powell. O mercado de planos de saúde odontológico é pulverizado, com o predomínio de empresas de pequeno porte, e apresenta um grande dinamismo, que favorece as empresas de pequeno, médio e alto porte. As modalidades analisadas concentram a maior proporção de beneficiários e receitas. A análise geral do desempenho do setor revela impressionante dinamismo na captação de clientes, mesmo após a criação da ANS. O regime de regulação tem imposto um novo padrão institucional à entrada, permanência e saída das empresas no mercado, que não afeta o desempenho setorial. Os dados analisados evidenciam que o setor de planos de saúde odontológicos é altamente rentável, apresentando uma grande capacidade na geração de receitas que explica o crescimento e a permanência destas modalidades no mercado. Os padrões de rentabilidade média, principalmente das empresas de odontologia de grupo, são extremamente elevados, ficando muito acima de qualquer atividade empresarial do Brasil.<br>This article analyzes the organizational model of the dental health industry. The main organizational leaders in this industry are the professional cooperatives and group dental insurance companies. The theoretical basis of the article is the organizational theory developed by Di Maggio and Powell. The dental health industry consists of a great number of small and very dynamic companies, however an expressive part of clients and profit are concentrated in a few large companies. The results show that the industry has expanded the number of clients after the creation of the National Health Insurance Agency. The regulation regime has forced institutional changes in the firms with regard to the market entry, permanence or exit patterns. There was no evidence that the regulatory rules have interfered with the development and financial conditions of the industry. The average profitability of the sector, especially among the group dental insurance companies, is extremely high
