OBJECTIVEReadmissions increasingly serve as a metric of hospital performance, inviting quality improvement initiatives in both medicine and surgery. However, few readmission reduction programs have targeted surgical patient populations. The objective of this study was to establish a transitional care program (TCP) with the goal of decreasing length of stay (LOS), improving discharge efficiency, and reducing readmissions of neurosurgical patients by optimizing patient education and postdischarge surveillance.METHODSPatients undergoing elective cranial or spinal neurosurgery performed by one of 5 participating surgeons at a quaternary care hospital were enrolled into a multifaceted intervention. A preadmission overview and establishment of an anticipated discharge date were both intended to set patient expectations for a shorter hospitalization. At discharge, in-hospital prescription filling was provided to facilitate medication compliance. Extended discharge appointments with a neurosurgery TCP-trained nurse emphasized postoperative activity, medications, incisional care, nutrition, signs that merit return to medical attention, and follow-up appointments. Finally, patients received a surveillance phone call 48 hours after discharge. Eligible patients omitted due to staff limitations were selected as controls. Patients were matched by sex, age, and operation type—key confounding variables—with control patients, who were eligible patients treated at the same time period but not enrolled in the TCP due to staff limitation. Multivariable logistic regression evaluated the association of TCP enrollment with discharge time and readmission, and linear regression with LOS. Covariates included matching criteria and Charlson Comorbidity Index scores.RESULTSBetween 2013 and 2015, 416 patients were enrolled in the program and matched to a control. The median patient age was 55 years (interquartile range 44.5–65 years); 58.4% were male. The majority of enrolled patients underwent spine surgery (59.4%, compared with 40.6% undergoing cranial surgery). Hospitalizations averaged 62.1 hours for TCP patients versus 79.6 hours for controls (a 16.40% reduction, 95% CI 9.30%–23.49%; p < 0.001). The intervention was associated with a higher proportion of morning discharges, which was intended to free beds for afternoon admissions and improve patient flow (OR 3.13, 95% CI 2.27–4.30; p < 0.001), and decreased 30-day readmissions (2.5% vs 5.8%; OR 2.43, 95% CI 1.14–5.27; p = 0.02).CONCLUSIONSThis neurosurgical TCP was associated with a significantly shorter LOS, earlier discharge, and reduced 30-day readmission after elective neurosurgery. These results underscore the importance of patient education and surveillance after hospital discharge.

Published: July 2017

Objective The aim of this study was to investigate patient characteristics and make an estimation of the cost of peritoneal dialysis (PD) and hemodialysis (HD) to Greek society during the economic crisis. Methods We recorded the characteristics and the total cost of dialysis treatment in 100 patients on PD and 100 on HD. Total costs included dialysis procedure, consumables, drugs, laboratory tests, food, and transportation fees (only HD), covered by patients’ insurance. Also included were medical and administrative salaries, purchase and maintenance of equipment and sanitary material, all covered by the state hospital. Results The mean patient age was 64.5 ± 16.8 years (PD) and 62.8 ± 15.1 (HD) ( p < 0,001). The most common cause of end-stage renal disease (ESRD) was diabetes (32% for PD and 24% for HD patients). A total of 35% of the PD patients were employed vs 4% of the HD patients ( p < 0,001). The mean distance from home for PD patients was 41.6 ± 17.3 km, while for HD patients, it was 9.4 ± 1.5 km ( p < 0,001). Mean monthly cost for PD and HD treatment per patient was €4,019.20 ± 1,126.30 and €3,254.30 ± 37.50, respectively, both fully covered by patients’ insurance. Mean monthly cost for PD or HD dialysis unit maintenance was €11,660.80 and €56,270.50, respectively, also fully covered by the state. Conclusion There is likely to be a considerable difference in terms of total cost of PD vs HD therapy, owing to the fact that the operational cost of a PD unit appears to be significantly lower than that of a HD unit.

Entre philosophie du droit et philosophie du langage, le chapitre examine les mécanismes duels de la pensée occidentale pour proposer ensuite une philosophie pragmatique – ou « impliquée » – qui refuse les dualismes et aborde le réel dans son épaisseur ontologique, épistémologique et sémiologique. Après un examen des arguments épistémologiques amenant à préférer une distinction langue/parole à une opposition, la contribution prend l’exemple du droit et de son exercice pour traiter du couple type/occurrence. De là, on constate que la connaissance ou science ne se confond pas avec l’« acte de connaissance » comme la langue ne se confond pas avec la parole ; du point de vue de l’exercice, et par contraste avec l’essence (ou quiddité), la parole c’est la langue exercée (et non pas appliquée) par et dans l’acte (de connaissance) ou « acte de parole » précisément. Se dessine une figure paradoxale du « dehors/dedans simultanément » qui ne se comprend qu’en tant que le langage doit son être à la mètis (aux savoir-faire, aux habiletés pratiques) bien plutôt qu’au seul logos (au raisonnement). Il s’agit ainsi de proposer une philosophie pragmatique que l’épaisseur du réel rend humble au point d’opérer avec mètis bien plus qu’avec logos, épousant des figures paradoxales, le « simultanément dedans/dehors » emblématiquement, que la linguistique éprouve en son méta-langage, lui-même langage en effet, que le droit pratique jusqu’en son fondement : on ne peut définir le droit sans en appeler au juridique, et réciproquement, démarche confinant au paralogisme et pourtant y échappant.

Ce texte propose une approche des politiques linguistiques qui met en évidence leur caractère de politique publique, les rendant comparables aux politiques poursuivies dans d’autres domaines tels que les transports, l’environnement ou la santé. Cette approche aide à préciser l’objet des politiques linguistiques dans une perspective qui favorise leur sélection, leur élaboration et leur évaluation : cet objet est la modification, dans un sens socialement souhaité, de l’environnement linguistique, notion nettement plus vaste que celle « paysage linguistique ». La politique linguistique emploie deux types d’instruments, la réglementation et l’incitation, applicables à différents champs dont ce texte propose une typologie combinant trois dimensions. Elle débouche sur l’identification de douze terrains d’action, où l’on distingue notamment l’écrit de l’oral. Un des enjeux que cette typologie met en relief est le risque de débordements non désirés d’un terrain d’action sur un autre, et l’on se penche ici sur le danger d’empiétement par l’écrit sur l’oral : certaines pratiques à l’écrit, autorisées voire instituées par une politique linguistique, peuvent-elles se propager au champ de l’oralité, ce qui reviendrait à une perte de maîtrise sur les politiques linguistiques ? Ce chapitre évalue ce risque dans le cas des politiques linguistiques universitaires en s’appuyant sur des exemples suisses. Il conclut que la diffusion de l’anglais dans les pratiques écrites (souvent utile pour des raisons d’accès à certains matériels scientifiques et pédagogiques) peut déboucher sur une diffusion de la langue anglaise dans les pratiques orales. Ceci peut être considéré comme une conséquence non désirée d’une politique linguistique informelle, qui mérite alors d’être recadrée dans l’intérêt à long terme de la diversité des langues et des cultures.
La société civile vue à l’aune de la résilience du système politique algérien
Authors: Hamadouche Louisa Dris-Aït 
Published: July 2017

L’évolution de la société civile en Algérie montre un rapport inversement proportionnel entre la force de l’État providence et la marge de manœuvre laissée au monde associatif. Or, malgré l’instauration du pluralisme et une présence numérique pléthorique, le mouvement associatif est unanimement considéré comme faible, au mieux embryonnaire, au point de s’apparenter davantage à un objet socio-politique qu’à un acteur social. La question qui se pose alors est : comment la société civile algérienne est-elle devenue partie prenante de la résilience du système politique algérien. Pour apporter des éléments de réponse à cette question, cet article commencera par décortiquer les caractéristiques de la société civile à travers l’autonomisation inachevée de l’individu citoyen, la politisation accrue et le piège de la rente. Il analysera ensuite la politique d’endiguement et de contrôle de la société civile par les gouvernants à travers le verrouillage juridique, la diabolisation ciblée et la division.

O estudo analisou a influência da Governança Corporativa e da estrutura de capital no gerenciamento de resultados em companhias abertas listadas na BM&FBovespa. Para tal, realizou-se pesquisa descritiva, com análise documental e abordagem quantitativa dos dados relativos aos anos de 2010 a 2013, utilizando amostra composta por 261 empresas. Os resultados revelaram destaque para os gerenciamentos de baixas proporções nos anos de 2010 e 2011, e aumento significativo dos gerenciamentos de maiores proporções em 2012 e 2013. Quanto à estrutura de capital, os resultados evidenciaram que os níveis de endividamento de curto prazo, longo prazo e de endividamento total, ao longo de todo o período investigado, foram superiores nas empresas não listadas no Índice de Ações com Governança Corporativa Diferenciada (IGCX) da BM&FBovespa. Constatou-se somente influência da Governança Corporativa para a redução do gerenciamento de resultados em 2010.

O presente estudo procura ressaltar a importância da adoção de determinadas componentes metodológicas para que uma produção intelectual possa se pretender verdadeiramente científica. Assim sendo, discorre sobre as principais “escolas” de metodologia – a saber, indutiva, dedutiva, hipotético-dedutiva e dialética – para, em seguida, buscar nas dissertações de mestrado de um Programa de Pós-Graduação em Administração menções – por parte dos autores – da adoção de um dos referidos métodos como paradigma para a condução da exposição acadêmica que realizaram. O estudo não analisa a adequação da escolha metodológica nem a correta aplicação dos pressupostos de cada método, mas sim, a ostensividade das escolhas feitas ou não. Trata-se de pesquisa de natureza descritiva, quanto aos fins, e classificada, quanto aos meios, como um estudo de caso. Analisadas todas as dissertações apresentadas entre os anos de 2010 e 2014 percebeu-se baixa taxa de aderência a uma das metodologias por parte dos autores que, se realizaram opções metodológicas não o explicitaram ao longo de seus textos.

Recentemente, a história tem ocupado um papel importante na área da Administração, especialmente no campo dos Estudos Organizacionais. Nesse sentido, o objetivo deste trabalho é analisar, por meio da pesquisa histórica, a (re)construção identitária da Galeria do Ouvidor, que foi um dos primeiros centros comerciais construídos em Belo Horizonte e que, atualmente, ainda se destaca entre as principais galerias da cidade. Por meio da pesquisa documental e da análise do discurso de narrativas temáticas de atores que trabalham atualmente na Galeria do Ouvidor, o presente estudo buscou ampliar a compreensão a respeito das identidades da organização desde a sua construção. Os resultados evidenciam que a história deste espaço se divide em diversas fases comerciais, em distintas identidades. Identidades estas que estão ligadas às mercadorias comercializadas na Galeria, as quais estão vinculadas à história da cidade de Belo Horizonte. Entretanto, embora novos clientes e produtos surjam nas diferentes identidades da galeria, permanecem resquícios de fases anteriores. Desse modo, a Galeria do Ouvidor pode ser compreendida, então, como um espelho da capital mineira.
Primary Signet Ring Cell Carcinoma of the Pancreas with a Good Response to Chemotherapy: Case Report and Literature Review
Authors: Radojkovic Milan , Ilic Dragana , Ilic Ivan 
Published: July 2017

Purpose Although pancreatic cancer is a common malignancy, signet ring cell carcinoma of the pancreas is a very rare histologic type with only 6 cases reported so far. We present a patient with primary signet ring cell carcinoma of the pancreas and a good response to neoadjuvant chemotherapy. Case report A 67-year-old woman presented at a regional hospital with a 2-week history of painless progressive jaundice. Abdominal computed tomography showed a tumor in the head of the pancreas, 4.5 cm in largest diameter. Since endoscopic biopsy and biliary stenting were not available, the patient had undergone palliative choledochoduodenostomy and tru-cut needle biopsy of the lesion. Histopathology revealed primary signet ring cell carcinoma of the pancreas. The tumor was considered borderline resectable and 3-month neoadjuvant chemotherapy with gemcitabine alone was administered due to the low creatinine clearance rates. Follow-up abdominal scan demonstrated very good response to chemotherapy and significant tumor regression to 1.5 cm in largest diameter. Radical cephalic duodenopancreatectomy was performed. Conclusion Significant tumor downsizing in our patient clearly demonstrates good response to neoadjuvant gemcitabine monotherapy. The optimal preoperative chemotherapy leading to tumor reduction and disease control in patients with borderline resectable and locally advanced pancreatic carcinoma is controversial, necessitating further randomized studies including combined chemoradiotherapy and multidrug combination regimens.

We are interested this paper in the modeling and numerical simulation of sand dune formation (on the effect of wind). We propose a simple model which will be approached by a classical numerical method in order to verify validity of our model to describe the phenomena of dune formation. Some numerical solutions of dune evolution and approximation error table are presented to verify that the simplified model is adopted to study the formation of sand dunes.

Abstract
An HPLC quadrupole time-of-flight (Q-TOF) MS method was developed for the identification of secondary metabolites in Leonurus turkestanicus V.I. Krecz. et Kuprian. Ethanolic and chloroform extracts from the plant’s aerial parts were tested. A total of 16 compounds (iridoid glycosides, phenylpropanoids, flavonoids, and nitrogen-containing compounds, as well as diterpene acetate derivatives) were identified and tentatively characterized based on (or using) their retention times and UV and Q-TOF-MS data. Previously reported aucubin (1),6-deoxy-8-acetylharpagid(2), and stachydrine(13, 15)and homostachydrine isomers(14, 16)were identified, along with a lavandulifolioside isomer(3),verbascoside(4),rutin(5),3-O-kaempferol rutinoside (6), and an unknown diterpene acetate(8).Compounds3–6were detected for the first time in this plant. Additionally. antimicrobial activity was evaluated. No significant differences were found between ethanolic and chloroform extracts of L. turkestanicus; however, the alcoholic extract showed stronger antifungal activity [minimal inhibitory concentration (MIC) of 2.5–5 mg/mL], whereas the chloroform extract showed stronger activity against the tested spore-forming Bacillus species (MIC 1.25–2.5 mg/mL).
Alcohol‐antiretroviral interactive toxicity beliefs as a potential barrier to HIV pre‐exposure prophylaxis among men who have sex with men
Authors: Kalichman Seth C , Eaton Lisa 
Published: July 2017

AbstractIntroduction: Pre‐exposure prophylaxis (PrEP) offers as much as 90% protection against HIV transmission. However, the effectiveness of PrEP depends on uptake and adherence to even intermittent dosing. Along with intoxication leading to unintentional non‐adherence, believing that alcohol mixed with pharmaceuticals is harmful (i.e., interactive toxicity beliefs) may lead to poor uptake and intentional non‐adherence.Methods: HIV‐negative sexually active men who have sex with men (N = 272) at a large Gay Pride event in Atlanta, GA, completed anonymous surveys of demographic characteristics, sexual behaviour, alcohol use and PrEP‐related alcohol interactive toxicity beliefs.Results: A total of 118 (43%) men surveyed had two or more male sex partners and condomless anal sex in the previous six months. Alcohol use was reported by over 90% of men and it was common for participants to believe that mixing alcohol and antiretrovirals is toxic; 75% endorsed at least one interactive toxicity belief. Among the 118 men who had engaged in condomless anal sex and had multiple sex partners, one in three stated that they were not interested in PrEP and men not interested in PrEP were significantly more likely to binge drink and hold interactive toxicity beliefs.Conclusions: These results mirror studies that find interactive toxicity beliefs are a potent predictor of intentional antiretroviral non‐adherence among people living with HIV and suggest interactive toxicity beliefs may impede PrEP uptake and adherence. Messages to increase PrEP awareness and adherence may also take steps to counter erroneous beliefs about mixing alcohol with antiretrovirals in the context of PrEP.

AbstractMultiangle Implementation of Atmospheric Correction (MAIAC) is a new Moderate Resolution Imaging Spectroradiometer (MODIS) algorithm that combines time series approach and image processing to derive surface reflectance and atmosphere products, such as aerosol optical depth (AOD) and columnar water vapor (CWV). The quality assessment of MAIAC AOD at 1 km resolution is still lacking across South America. In the present study, critical assessment of MAIAC AOD550 was performed using ground‐truth data from 19 Aerosol Robotic Network (AERONET) sites over South America. Additionally, we validated the MAIAC CWV retrievals using the same AERONET sites. In general, MAIAC AOD Terra/Aqua retrievals show high agreement with ground‐based measurements, with a correlation coefficient (R) close to unity (RTerra:0.956 and RAqua: 0.949). MAIAC accuracy depends on the surface properties and comparisons revealed high confidence retrievals over cropland, forest, savanna, and grassland covers, where more than 2/3 (~66%) of retrievals are within the expected error (EE = ±(0.05 + 0.05 × AOD)) and R exceeding 0.86. However, AOD retrievals over bright surfaces show lower correlation than those over vegetated areas. Both MAIAC Terra and Aqua retrievals are similarly comparable to AERONET AOD over the MODIS lifetime (small bias offset ~0.006). Additionally, MAIAC CWV presents quantitative information with R ~ 0.97 and more than 70% of retrievals within error (±15%). Nonetheless, the time series validation shows an upward bias trend in CWV Terra retrievals and systematic negative bias for CWV Aqua. These results contribute to a comprehensive evaluation of MAIAC AOD retrievals as a new atmospheric product for future aerosol studies over South America.
Regional distribution of large blowdown patches across Amazonia in 2005 caused by a single convective squall line

Published: July 2017

AbstractIn mid‐January 2005 a convective squall line traversed 4.5 × 106 km2 of Amazonia from southwest to northeast. As seen in Landsat images, this atypical convective storm left blowdown imprints with diffuse geometry, unlike the fan‐shaped wind disturbance of much more frequent east‐to‐west propagating squall lines. Previous work reported 0.2% of the forest area damaged by this one relatively rare event within one Landsat image and assumed similar disturbance across the entire traverse. We mapped convective wind damage impact to the region in 2005 by identifying large‐scale (>4 ha) blowdown imprints in 30 Landsat images. The diffuse‐type imprints associated with this single squall line contributed up to 60–72% of total 2005 wind‐disturbed area detected across the region, but damage was highly concentrated in central Amazonia. Consequently, the distribution of large wind damage patches in 2005 across Amazonia was very different from long‐term average. Regional distribution of wind‐driven tree mortality for smaller patch sizes remains unknown.
