Changing clinical and therapeutic trends in tentorial dural arteriovenous fistulas: a systematic review
BACKGROUND AND PURPOSE: Tentorial dural arteriovenous fistulas are characterized by a high hemorrhagic risk. We evaluated trends in outcomes and management of tentorial dural arteriovenous fistulas and performed a meta-analysis evaluating clinical and angiographic outcomes by treatment technique. MATERIALS AND METHODS: We performed a comprehensive literature search for studies on surgical and endovascular treatment of tentorial dural arteriovenous fistulas. We compared the proportion of patients undergoing endovascular, surgical, and combined endovascular/surgical management; the proportion of patients presenting with ruptured tentorial dural arteriovenous fistulas; and proportion of patients with good neurologic outcome across 3 time periods: 1980-1995, 1996-2005, and 2006-2014. We performed a random-effects meta-analysis, evaluating the rates of occlusion, long-term good neurologic outcome, perioperative morbidity, and resolution of symptoms for the 3 treatment modalities. RESULTS: Twenty-nine studies with 274 patients were included. The proportion of patients treated with surgical treatment alone decreased from 38.7% to 20.4% between 1980-1995 and 2006-2014. The proportion of patients treated with endovascular therapy alone increased from 16.1% to 48.0%. The proportion of patients presenting with ruptured tentorial dural arteriovenous fistulas decreased from 64.4% to 43.6%. The rate of good neurologic outcome increased from 80.7% to 92.9%. Complete occlusion rates were highest for patients receiving multimodality treatment (84.0%; 95% CI, 72.0%-91.0%) and lowest for endovascular treatment (71.0%; 95% CI, 56.0%-83.0%; P < .01). Long-term good neurologic outcome was highest in the endovascular group (89.0%; 95% CI, 80.0%-95.0%) and lowest for the surgical group (73.0%; 95% CI, 51.0%-87.0%; P < .03). CONCLUSIONS: Patients with tentorial dural arteriovenous fistulas are increasingly presenting with unruptured lesions, being treated endovascularly, and experiencing higher rates of good neurologic outcomes. Endovascular treatment was associated with superior neurologic outcomes but lower occlusion rate
“I don’t want to look sick skinny”: Perceptions of body image and weight loss in Hispanics living with HIV in South Texas
Objective: Obesity is rising in people with HIV (PLWH) and Hispanics. Both HIV and obesity are associated with cardiovascular disease morbidity and mortality. Our goal is to understand perceptions of body image and lifestyle in Hispanics with HIV to adapt interventions appropriately.
Methods: We conducted semi-structured interviews with 22 Hispanic PLWH and 6 providers. Purposive sampling selected patient participants across weights and genders. Interviews were coded and analyzed using grounded theory, comparing perspectives between patients with and without obesity, and patients and providers.
Results: Participants felt obesity and diabetes were “normal” in the community. Patients exhibited understanding of healthy diet and lifestyle but felt incapable of maintaining either. Traditionally Hispanic foods were blamed for local obesity prevalence. Five patients equated weight with health and weight loss with illness, and four expressed concerns that weight loss could lead to unintentional disclosure of HIV status. Participants with overweight or obesity expressed awareness of their weight and felt shamed by providers. Providers found weight loss interventions to be ineffective.
Conclusion: Interventions in this population must address identified barriers: overweight/obesity as a normative value, lack of self-efficacy, cultural beliefs surrounding food, fear of HIV-associated weight loss and stigma, and provider perspectives on intervention futility
Occurrence of Legionella in beach shower facilities
It has been analyzed 36 samples of water proceeding from beach
shower facilities: 7 of these were found to be contaminated with
Legionella (19.44%). In three showers, L. pneumophila 1 was
reported, in two L. pneumophila 2-14; in another two cases L.
pneumophila 2-14 was found together with Legionella sp. and L.
pneumophila 1 together with L. pneumophila 2-14.
This study, which confirms the circulation of Legionella in our
region of southern Italy, extends the list of the possible sources
of infection, including also public and private beaches among
the contaminated sites.
It is the Authors opinion that when evaluating the risk in these
cases we should take into account that the crowding of the
beaches in the summer months and the communal nature of
shower use in these periods increases the frequency of exposure
of children and old people. These vulnerable categories are significantly
more likely to develop the disease once infected
The role of fluoride in the nano-heterogeneity of bioactive glasses
Fluoride-containing bioactive phospho‐silicate
glasses have recently attracted interest for dental applications, particularly as remineralising additives in dentifrices, and are potentially attractive for bone regeneration, particularly in patients suffering from osteoporosis. The incorporation of fluoride into phospho‐silicate glasses is also attractive from a structural viewpoint: Fluoride complexes modifier ions rather than binding to the silicate network, and it thereby adds a significant ionic
contribution to the average character of chemical bonds in the system. Molecular dynamics simulations have suggested that this
also results in the formation of nano-eterogeneities. In this paper, we review the
current knowledge on the structural role of fluoride in bioactive glasses, with a particular focus on inhomogeneities on a nano-‐scale

TYPES OF IDIOMS AND STRATEGIES IN TRANSLATING IDIOMS IN THE NOVEL THE GIRL ON THE TRAIN BY PAULA HAWKINS
The objectives of this research are to identify the types and strategies in translating idioms used in Paula Hawkins' novel The Girl on the Train. The research methodology applied isdescriptive qualitative.The results show that the types of idioms (ODell and McCarthy 2010)found in the novel are similes, binomials, proverbs, euphemisms, cliché, and fixed statement and other language. Using the theory by Baker (2011), the idioms in the novel are mainly translated using the strategy; translation by phrase. Other strategies that are also applied are using idioms of similar meanings but dissimilar forms, using idioms of singular and form, translating by omission of entire idioms, and borrowing the source language. Keywords: Idioms; Translation Strategy
Random walks and search in time-varying networks
The random walk process underlies the description of a large number of real
world phenomena. Here we provide the study of random walk processes in time
varying networks in the regime of time-scale mixing; i.e. when the network
connectivity pattern and the random walk process dynamics are unfolding on the
same time scale. We consider a model for time varying networks created from the
activity potential of the nodes, and derive solutions of the asymptotic
behavior of random walks and the mean first passage time in undirected and
directed networks. Our findings show striking differences with respect to the
well known results obtained in quenched and annealed networks, emphasizing the
effects of dynamical connectivity patterns in the definition of proper
strategies for search, retrieval and diffusion processes in time-varying
network
Assessment of preference Liriomyza spp. in different chickpea genotypes and effect of Melia azedarach L. extract : preliminary results
En Argentina se están desarrollando
genotipos de garbanzo (Cicer arietinum L.)
para adecuarlos a las distintas zonas de
producción. Estos presentan diferentes
fenotipos lo que podría afectar las preferencias
de oviposición de los insectos herbívoros de
hábito minador. Los objetivos de este trabajo
fueron: 1) determinar si las hembras del
género Liriomyza spp. muestran preferencia
por algún genotipo de garbanzo, y 2) evaluar
el efecto del extracto de Melia azedarach
sobre las líneas de garbanzo que resultaran
susceptibles. Se sembraron dos líneas
selectas y dos cultivares de C. arietinum
que presentan hojas unifoliadas enteras
o compuestas, en el Campo Experimental
de la Facultad de Ciencias Agropecuarias,
Universidad Nacional de Córdoba, en bloques
al azar con tres repeticiones. Para analizar
la preferencia, mediante censos semanales
se evaluó la presencia de las larvas de las
moscas en el período julio-septiembre. Los
dípteros eligieron de manera significativa
los genotipos de hoja entera y grande.
Posteriormente, las plantas con hojas
minadas de las variedades preferidas fueron
sometidas a tratamiento con el extracto
botánico. Para ello se marcaron cinco plantas
de cada bloque: a 15 se les aplicó extracto
(10%) y a las otras 15 agua (control). Se
observó que el número de hojas minadas,
de pupas y adultos emergidos disminuyeron
en los tratamientos con el extracto. Estudios
complementarios serán necesarios para
poder considerar este compuesto natural en
un plan de manejo del herbívoro.In Argentina several genotypes of chickpea
(Cicer arietinum L.) have been developed to be
cropped in environmentally different production
areas. These have different phenotypes which
could affect oviposition preferences of the
behavior of leafminer. The aims of this study
were two-fold: 1) to determine if leafminer
Liriomyza spp. has a preference for any chickpea
genotype, and 2) to evaluate the insecticide
effect of Melia azedarach extracts on susceptible
genotypes. Two selected lines and two cultivars
of C. arietinum were planted in the experimental
field of the FCA, UNC, in randomized blocks with
three replications. Through weekly surveys, the
preference of the flies in the period from July to
September was determined by recording their
presence in plants. The leafminer significantly
choice the genotype with entire and large leaves.
Subsequently, they were treated with botanical
extracts by selecting five plants on each
block: fifteen of them were treated with a 10%
M. azederach extract and the other fifteen only
with water (control). Number of mined leaves,
pupae and emerged adults decreased after the
treatment with the extract. Additional studies are
needed to consider this natural compound in a
management plan for the herbivore.Fil: Ávalos, Delia S..
