Authors: Murillo Gómez DDS, MSc Fabián , De Goes DDS, MSc, PhD Mario F. 
Published: July 2017

The present study evaluated the bond strength between glass-ceramic and resin cement, using different silane treatments, performing no previous hydrofluoric acid (HF) etching on ceramic surface, after short- and long- term storage. One hundred and eighty glass-ceramic plaques (IPS e.max CAD®) were polished and divided into six groups (n=30) to receive different silane treatments: (1) RCP-RelyX Ceramic Primer® (one-bottle silane), (2) RCP+SB-RelyX Ceramic Primer and Adper Singlebond2® (silane plus separated adhesive), (3) SBU-Scotchbond Universal® (silane-containing universal adhesive), (4) CP-Clearfil Ceramic Primer® (silane/MDP primer), (5) NC-no-silane (negative control) and (6) PC-Previous HF etching (5%, 20s) plus RelyX Ceramic Primer® (positive control). Two resin cement cylinders (Rely X Ultimate®) were built on each plaque. Each group was divided into two sub-groups to be stored for 24 hours (24h) or 6 months (6mo) in distilled water at 37°C (n=15). Then microshear (µSBS) testing was performed. Failure mode was analyzed using scanning electron microscopy (SEM). Data were statistically analyzed by two-way ANOVA and Tukey´s test (α=0.05). Both factors and their interaction resulted statistically significant (p≤0.05). PC obtained the highest µSBS values (in MPa) at both storage times (24h: 28.11±2.44; 6mo: 19.10±3.85). After 24h storage, groups RCP+SB (10.86±3.62), SBU (8.37±4.33) and CP (8.05±3.62) were not statistically different from NC (8.00±2.51); only RCP (19.73±4.63) and PC obtained higher values. After 6 months, only PC showed higher values than NC (0.04±0.01). Cohesive failure in resin cement was more prevalent for RCP-24h and PC, while adhesive failure was more frequent among all other groups. Clinical relevance: None of the commercially available silane primers tested, improve long- term ceramic/cement bonding without performing HF etching on ceramic surface. Combination of HF acid and silane, remain as a gold standard treatment for glass-ceramic materials.

Background. Prevalence of asthma (BA) among pregnant women reaches 12%. Obstetric complications (preeclampsia, placental insufficiency, IUGR, etc.) mainly occur in the absence of control of asthma. Aspects of the placenta status in women with chronic allergic respiratory disease are not well understood.
Purpuses and tasks — studying the expression of markers of immature dendritic cells (CD35) and natural killer (CD57) cells in the placenta of patients with asthma, depending on the of severity, control and the type of therapy.
Materials and methods. The study involved 200 pregnant women, including 170 with asthma (44 patients with mild intermittent, 52 with mild persistent, 61 with moderate and 13 with severe asthma), and 30 patients without pulmonary and allergic diseases. We analized complications and pregnancy outcomes, conducted the immunohistochemical study of placental samples of 134 patients for the expression of CD35 (marker of immature dendritic cells) and CD57 (marker of NK cells) on cryostat sections, immunomorphological study of the placenta with determination of the fixation of pathogenic immune complexes (PIC), IL-6, IL- 4, IL-10 in the placenta.
Results. CD35 expression in the placenta of women with asthma is increased, while in patients undergoing preeclampsia CD35 expression is lower, especially in cases of uncontrolled asthma in the 3rd trimester. In all cases with persistent and incompletely controlled asthma, the expression of the natural killer marker (CD57) in the placenta correlates with the presence of PIC, IL-6, IL-4, IL-10 and inflammatory changes in the placenta. Conclusions. The results of the study suggest that a decrease in CD35 expression in cases with the combination of uncontrolled persistent asthma and preeclampsia seems to deplete the mechanisms of the immune response. Increased NK cell marker expression (CD57) in the placenta of women with uncontrolled and persistent asthma indicates on the cytotoxic role of this subpopulation of cells, leading to morphological and immune changes in the placenta that adversely affect the fetus and newborn.
Advisability of using early generation Cephalosporines for prevention and treatment of postpartum infection
Authors: Korobkov Nikolay A. 
Published: July 2017

Introduction: the following research investigates an availability of a long-lime treatment of postpartum infection by using of Cephalozolin (the Cephalosporine of generation I).
Matherials and Methods. Lochia samples were obtained from the uterine cavities of 21 puerperal women who did not receive drug after delivery and were cultured for the identification and the determination of the susceptibilities of the clinical isolates to Cephalozolin. The concentrations of Cephalozolin in the supernatants were measured by highperformance liquid chromatography.
Results. We determined the sensivity of the most clinically important bacteria to Cephazoline and its penetration rate to the uterine cavity. We found out the following bacteria which are sensible to Cephazoline – S. agalactiae, E. coli, K. pneumoniae, E. aerogenes. A low rate of Cephazoline ≤ 0,78 mg/ml was inhibited the growth of mentioned above bacteria. Cephazoline is also active as for S. aureus – MIC90 and was equal 3.13 mg/ml. In 3 hours after the injection of 1.0 gr of Cephazoline there was a maximum concentration in a venous blood – 1.63 mg/ml. The concentration of Cephazoline in lochia was rising gradually and it maximum in the uterus cavity in 5 hours was 1.26 mg/ml, and then its slowly went down.
Conclusions. The mention above results let us suggest that Cephazoline is penetrates actively to lochia and its still has a good antibacterial effect. Cephazoline is still a treatment of choice as for prevention and a treatment of postpartum surgical site infections by a sensitive microorganism.

<p>Stent fracture (SF) is a rare adverse complication that might occur in peripheral and coronary artery, particularly with sirolimus-eluting stent (SES). The structural characteristics of this device with closed cell design and stainless steel scaffolding prompts to a probable fracture of stent. This adverse event is strongly associated with in-stent restenosis (ISR), target lesion revascularization (TLR) and stent thrombosis (ST). We report the fluoroscopic and tomographic patterns of fractured stent associate with restenosis and thrombotic sub-occlusion treated by bioresorbable vascular scaffold (BVS). To our knowledge, this is the first published report of SF that was treated by BVS.</p>

Na Amazônia, é possível promover o uso das terras, de forma aceitável, através de uma gestão compatível com a fertilidade do meio natural. Para isso é necessário que, por um lado, se conheça as relações entre as formas de uso e o meio ambiente e, por outro, as características do meio natural e as condições dos utilizadores desse meio. Estudos que relacionam, através de metodologias econômicas e estatísticas, o valor bruto da produção, em diversas expressões temporais e espaciais, com dados sobre crédito de fomento e produção de C & T, considerando o conjunto de estabelecimentos de agricultura familiar, indicam para estes a existência de um fraco ambiente institucional. Apesar desse ambientedesfavorável, o fomento praticado inicialmente pelo FNO e depois pelo PRONAF, ermitiram a transformação de sistemas de produção com a inclusão de culturas permanentes, pecuária de corte e pecuária de leite. A silvicultura e a pecuária de leite são, na Amazônia, as produções que associam maior possibilidade econômica de expansão com capacidade endógena de desenvolvimento. A pecuária de corte, que tem maior expressão no grupo patronal, é a que tem menor capacidade endógena de desenvolvimento.No Território da Cidadania do Baixo Tocantins os sistemas de produção agrícola maisimportantes são os de cultivos temporários e de cultivos permanentes. Os cultivos temporários na terra firme, pela dificuldade de intensificação nos moldes da agricultura industrial, não constituem a melhor opção para os agricultores familiares. Por outro lado, existem, já acumulados, procedimentos de base agroecológica, que constituem inovações, que vêm sendo difundidas por ONGs. São exemplos: a proteção do solo com a “palhada” dos cultivos; a manutenção das capoeiras ou a introdução de sistemas de produção, como os sistemas agroflorestais, a horticultura, a fruticultura e a apicultura, conforme sãopraticados hoje por diversos agricultores incentivados pela Associação Paraense de Apoio às Comunidades Carentes. Estes procedimentos permitem a intensificação do trabalho, sendo mais compatível com a manutenção da biodiversidade e da biomassa, e que tem um menor efeito na degradação do solo, além de maior capacidade de expansão por atenderem a mercados urbanos regionais.
Impactos das limitações epistêmicas sobre sustentabilidade nas ações do PRONAF na porção sudeste do Pará
Authors: Silva Luis Mauro Santos , Martins Sérgio Roberto 
Published: July 2017

Uma das mudanças nas recentes políticas sociais ligadas ao contexto agrário brasileiro é o reconhecimento da agricultura familiar como categoria estratégica no novo processo de desenvolvimento rural brasileiro. No entanto, as dificuldades metodológicas e de percepção de sua heterogeneidade sócio-ambiental limitam a efetividade das políticas públicas, particularmente do Pronaf. No porção Sudeste do Pará, Amazônia brasileira, os avanços no processo de regularização fundiária não têm refletido nos investimentos produtivos. Alguns fatores reforçam uma visão descontextualizada de sustentabilidade que se limita, geralmente, à dimensão econômica. Entre eles se destacam os entraves na liberação dos recursos disponíveis, o desequilíbrio na distribuição desses recursos, o engessamento burocrático das agências financiadoras e a falta de uma visão sistêmica e de percepção integral dos agroecossistemas pelos agentes de desenvolvimento. O presente artigo chama a atenção para a necessidade de abordar o tema da sustentabilidade para além do aspecto econômico e não mais conceber a sustentabilidade como "ponto de chegada". O caminho escolhido foi tentar compreender o desenvolvimento sustentável como um processo, rumo à construção de sua nova episteme. Tanto do ponto de vista teórico quanto metodológico esse é um desafio imprescindível de ser enfrentado.

Published: July 2017

Mandatory Sistem Verifikasi Legalitas Kayu (SVLK) menjadi non tarif barrier yang dibuat oleh pemerintah. Seluruh produk kayu tidak dapat menembus semua pasar ekspor jika tidak memiliki sertifikat legalitas kayu dan dokumen v-legal. Deregulasi menimbulkan kerisauan bagi industri furnitur kayu. Tarik ulur regulasi menunjukkan ketidakkonsistenan pemerintah atas regulasi yang dibuatnya. Akibatnya, selama tujuh tahun ditetapkan kebijakan ini belum memberikan dampak signifikan bagi peningkatan daya saing industri furnitur kayu. Oleh sebab itu, diperlukan transformasi regulasi yang lebih implementatif dan sesuai dengan kebutuhan industri. Hasil kajian menyatakan bahwa pemerintah perlu melakukan evaluasi implementasi SVLK secara menyeluruh dengan melibatkan industri dan seluruh stakeholder kehutanan. Pemerintah juga harus melakukan deregulasi antara lain dengan cara menurunkan standar biaya sertifikasi dan menetapkan standar maksimum tarif sertifikasi yang diberlakukan lembaga verifikasi (LV). Mandatory SVLK khusus pasar Uni Eropa dan niche market yang dilandasi dengan voluntary partnership agreement (VPA) seperti halnya yang dilakukan dengan Uni Eropa.
Relationship Between Age and Rotator Cuff Retear
Authors: Diebold Georgia , Lam Patrick , Walton Judie , Murrell George A.C. 
Published: July 2017

Background:
The prevalence of rotator cuff tears increases with age, and many patients undergo surgical repair. Retears are not uncommon, with rates ranging between 9% and 36% in recent studies, and are a major concern. The aim of this study was to investigate the relationship between patient age and the chance of healing following rotator cuff repair.

Methods:
This was a retrospective cohort study of patients who had undergone arthroscopic rotator cuff repair performed by a single surgeon. All patients had an ultrasound performed by a musculoskeletal sonographer 6 months after rotator cuff repair to assess the repair integrity.

Results:
The cohort of 1,600 patients was normally distributed in terms of age, with a mean age (and standard error of the mean) of 59 ± 0.3 years and a range of 15 to 91 years. The 212 patients (13%) who had a retear at 6 months were also normally distributed in terms of age, with a mean age of 65 ± 0.8 years and a range of 15 to 88 years. The retear rate in patients <50 years old was 5%. This increased to 10% in patients aged 50 to 59 years, 15% in those aged 60 to 69 years, 25% in those aged 70 to 79 years, and 34% in those aged ≥80 years. Multiple logistic regression analysis showed that patient age was an independent factor strongly associated with retears.

Conclusions:
The rate of rotator cuff retears is low in patients <50 years of age. The relationship between age and rotator cuff retears is linear in patients 50 to 69 years of age, with an increase of 5% between decades, and increases substantially in patients ≥70 years old.

Authors: Goudie E.B. , Clement N.D. , Murray I.R. , Lawrence C.R. , Wilson M. , Brooksbank A.J. , Robinson C.M. 
Published: July 2017

Background:
We aimed to evaluate the effect of clavicular shortening, measured with 3-dimensional computed tomography (3DCT), on functional outcomes and satisfaction in patients with healed displaced midshaft clavicular fractures up to 1 year following injury.

Methods:
The data used in this study were collected as part of a multicenter, prospective randomized controlled trial of open reduction and plate fixation compared with nonoperative treatment for acute, displaced midshaft clavicular factures. Patients who were randomized to nonoperative treatment and had healed by 1 year were included in the present study. Clavicular shortening relative to the uninjured, contralateral clavicle was measured on 3DCT. Outcome analysis was conducted at 6 weeks, 3 months, 6 months, and 1 year following injury and included the Disabilities of the Arm, Shoulder and Hand (DASH), Constant, and Short Form-12 (SF-12) scores and patient satisfaction.

Results:
In the original trial, 105 patients were randomized to nonoperative treatment. Thirteen patients were lost to follow-up, leaving 92 patients, and an additional 16 (17%) developed nonunion and were excluded from the present study. Of the remaining 76 patients, 48 who had a 3DCT scan that included the whole length of both clavicles were included in the present study. The shortening of the injured clavicles, relative to the contralateral side, was a mean (and standard deviation) of 11.3 ± 7.6 mm, with a mean proportional shortening of 8%. Proportional shortening did not significantly correlate with the DASH (p ≥ 0.42), Constant (p ≥ 0.32), or SF-12 (p ≥ 0.08) scores at any point during follow-up. There was no significant difference in the mean DASH or Constant scores at any follow-up time point when the cutoff for shortening was defined as 1 cm (p ≥ 0.11) or as 2 cm (p ≥ 0.35). There was no significant difference in clavicular shortening between satisfied and unsatisfied patients (p ≥ 0.49).

Conclusions:
The present study demonstrated no association between shortening and functional outcome or satisfaction in patients with healed displaced midshaft clavicular fractures up to 1 year following injury.
