Authors: Crespi Joan , Bratbak Daniel , Dodick David , Matharu Manjit , Jamtøy Kent Are , Tronvik Erling 
Published: February 2019

Background: The sphenopalatine ganglion (SPG) is a target for several headache syndromes. Most of the groups targeting the SPG do not localize it directly, and this might account for some therapeutic failures. As the SPG cannot be seen on computerized tomography (CT) scans, magnetic resonance image (MRI) must be used to visualize the ganglion. It would be advantageous to be able to predict the location of the SPG on CT scans for those using fluoroscopy or CT-guided injections and for those in whom MRI is not accessible or contraindicated. Methods: We localized the SPG in 21 Caucasian patients (21 right and 17 left ganglia; total 38) in 3 tesla MR images subsequently fused with CT scans. We measured the distance from the SPG to two bony landmarks identified on CT scans. We then applied the average distances to find an estimated position of the SPG. The first landmark was the center of the anterior opening of the vidian canal (VC). The second landmark was a point on the sphenoidal bone, defined in an axial plane at the level of the center of the VC (S-point). The predicted position of the SPG measured from the VC and the sphenoidal bone were referred to as, respectively, vcSPG and sSPG. Finally, the distances between the SPG, as seen on MRI, and predicted vcSPG/sSPG were calculated. Results: The average distance between SPG as seen on the MRI images and the estimated position based on CT images were 1.82 mm (SD 0.83, range 0.22–3.57 mm) for vcSPG and 2.09 mm (SD 0.99, range 0.71–4.79 mm) for sSPG. Conclusions: The localization of the SPG can be predicted on CT images using bony landmarks. Localization of the SPG may be important in achieving successful therapeutic outcomes for treatments that are directed toward the SPG.

Abstract

Background
Proteinuria is a marker of poor outcomes in several diseases; however, few studies have been conducted to explore the prognostic value of proteinuria, assessed by urine dipstick test, for clinical outcomes in patients with type B acute aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR).

Methods
Consecutive patients with TBAD undergoing TEVAR were enrolled from January 2010 to July 2015. Proteinuria was defined as trace or higher, according to the results of urine dipstick testing. Associations among proteinuria and adverse events were evaluated.

Results
In total, 671 patients with a mean age of 44±15 years were included in the analysis. Proteinuria was detected in 281 patients (41.9%) before TEVAR. Multivariate logistic regression analysis showed that C-reactive protein and impaired renal function were independent predictors for proteinuria. During hospitalization, 21 patients died. In-hospital mortality was higher in patients with proteinuria (1.5% vs. 5.3%, p=0.005). After a median 3.4 years follow up, the post-TEVAR death rate was 10.4% (85 patients were lost to follow-up). The long-term cumulative mortality was significantly higher in patients with proteinuria (17.2% vs. 8.2%, log-rank=11.36, p=0.001). Multivariate Cox survival modeling indicated that proteinuria was significantly associated with long-term death, after adjustment for potential confounding risk factors (HR=1.92, p=0.012).

Conclusions
Pre-TEVAR proteinuria was identified as a prognostic marker in patients with TBAD and has potential for application as a convenient and simple risk assessment method before TEVAR.
Irradiated rubber composite with nano and micro fillers for mining rock application
Authors: Eyssa Hanan M. , Mohamed Wael S. , El-Zayat Mai M. 
Published: February 2019

Abstract
In this work, nanosilica and micro carbon black (CB) as a fillers were used to improve the properties of styrene butadiene rubber/natural rubber blends (SBR/NR) crosslinked by γ radiation. Nanosilica was prepared from silica sand and used as eco-friendly material. These composites were characterized by field emission scanning electron microscopy (FESEM) and the measurements of the physic-mechanical and thermal properties were measured. Field emission scanning electron microscopy showed that the composites reinforced by nanosilica and the measurements of the CB are uniformly dispersed in the blends matrix. The results showed that the physico-mechanical and thermal properties were improved indicating a good interaction between the fillers and rubber matrix. The volume fraction measurements confirmed the formation of crosslinking network structure. Meanwhile, the reinforcement of SBR/NR blend loaded with nanosilica showed improved mechanical than blend loaded with both the nanosilica/carbon black and the CB alone. The highest enhancement was obtained for the three fillers by using a concentration of 35 phr at a dose of 150 kGy of γ-irradiation. Thermogravimetric analysis (TGA) indicated that the thermal stability of SBR/NR blend reinforced by nanosilica is higher than those blends reinforced with combined filler the silica. It was also found that the irradiated SBR/NR nanocomposites were more stable than the un-irradiated ones.

Abstract

Background and aims
The co-morbidity between pain and depression is a target of interest for treatment. However most of the published literature on the topic has used clinical cohorts as the population of interest. The goal of this study was to use a nationally representative sample to explore how health outcomes varied across pain and depression status in a cohort sampled from the general US population.

Methods
This was a cross-sectional analysis of adults ≥18 years in the 2009–2010 National Health and Nutrition Examination Survey. The cohort was stratified into: no pain/depression, pain alone, depression alone, and pain with depression. The primary outcome was self-reported general health status, and secondary outcomes were healthcare visits, overnight hospital stays and functional limitation. Survey weighted logistic regression was used to adjust for potential confounders.

Results
The cohort consisted of 4,213 individuals, of which 186 (4.4%) reported concurrent pain and depression. 597 (14.2%) and 253 (6.0%) were classified with either pain or depression alone, respectively. The majority of individuals with co-morbid pain and depression reported poor health (65.1%, p<0.001) and were significantly more likely than those with neither condition to rate their health as poor after adjustment (OR: 7.77, 95% CI: 4.24–14.26, p<0.001). Those with pain only or depression only were also more likely to rate their health as poor, albeit to a lesser extent (OR: 2.21, 95% CI: 1.21–2.34, p<0.001; OR: 3.75, 95% CI: 2.54–5.54, p<0.001, respectively). A similar pattern was noted across all secondary outcomes. Most notably, those with co-morbid pain and depression were the most likely to endorse functional limitation (OR: 13.15, 95% CI: 8.00–21.61, p<0.001). Comparatively, a similar trend was noted amongst those with pain only or depression only, though with a reduced effect size (OR: 4.23, 95% CI: 3.12–4.77, p<0.001; OR: 5.13, 95% CI: 3.38–7.82, p<0.001).

Conclusions
Co-morbid pain and depression in the general population resulted in markedly worse outcomes versus isolated pain or depression. Further, the effect appears to be synergistic. Given the substantial burdens of pain and depression, future treatments should aim to address both conditions simultaneously.

Implications
As a result of the co-morbidity between pain and depression, patients presenting with either condition should increase the index of suspicion among clinicians and prompt screening for the reciprocal condition. Early intervention for co-morbid pain and depression has the potential to mitigate future incidence of chronic pain and major depression.

Authors: Gorbunova M. V. , Babak S. L. , Malyavin A. G. 
Published: February 2019

Background:obstructive sleep apnea (OSA) is associated with high prevalence of arterial hypertension (AH), obesity, violation of carbohydrate metabolism and dyslipidemia. However, the effects of CPAP therapy to improve epicardial fat thickness of the OSA patient with AH the are poorly understood and poorly studied.Study objective:the aim of the study was to investigate 12-month effects of CPAP therapy with auto-adaptation to inhalation and exhalation of the OSA patient with AH and metabolic disorders (A-Flex therapy) on epicardial fat thickness (EFT).Methods:to the prospective single-center study were included 310 patients with OSA and AH (273 male, 45,3 ± 10,4 yr.) with apnea-hypopnea index (AHI) >5 events /hour. The night polygraphy study (PG) was performed to calculate AHI, oxygen desaturation index (ODI), mean nocturnal saturation (SpO 2 ) by the rules of American Academy of Sleep Medicine (AASM). The calculation of the epicardial fat thickness (EFT), the size and volume of the heart cavities, left ventricular mass index (LVMI) were performed by two-dimensional echocardiography. Endothelial functionof blood vessels determined by finger test was measured according to peripheral arterial tone (PAT). The reactive hyperemia index (RHI) and augmentation index (AI) was calculated. Optimal level of A-Flex therapy was adjusted at home. AHI, the level of air leakage, average pressure and compliance to CPAP treatment were established in accordance with international requirements.Results:after 3 months of A-Flex therapy we found a significant decrease of HOMA-IR -1,09 (95% Cl from -1,74 to -0,96; P=0,021), decrease AI -10.8% (95% Cl from -13,70 to -4.6; P=0,001), decrease EFT -1,26 mm (95% Cl from -2,2 to -0,95; P=0,001) in mild OSA patients. After 6 months of A-Flex therapy we found a significant decrease of HOMAIR -2,81 (95% Cl from -3,74 to -1,46; P=0,001), decrease AI -15.6 % (95% Cl from -17,23 to -11,75; P=0,001), decrease EFT -2,15mm (95% Cl from -3,2 to -1,5; P=0,001) in moderate OSA patients. After 12 months of A-Flex therapy we found a significant decrease of HOMA-IR -4,22 (95% Cl from -5,36 to -2,35; P=0,001), decrease AI -21,05 % (95% Cl from -26,5 to -17,4; P=0,001), decrease EFT -4,0 mm (95% Cl from-5,8 to -2,7; P=0,001) in severe OSA patients.Conclusions:The 12-month A-Flex therapy in moderate and severe OSA patients with AH has a significant therapeutic effect of stabilization systolic and diastolic blood pressure, level of blood lipids and epicardial fat thickness, level of endothelial dysfunction. The 12-month A-Flex therapy has to able to reduce the risks of cardiovascular events in moderate and severe OSA patients with acute metabolic manifestations.

The aim. Find out the nature of the changes of the hepatobiliary system in patients with intestinal bacterial overgrowth and study the possible mechanisms of their association.Materials and methods. 148 patients with intestinal bacterial overgrowth and intestinal dysbiosis were examined. The level of total cholesterol, cholestasis and cytolysis markers was determined in the blood using the analyzer «Labsystems» (Finland). Intestinal bacterial overgrowth syndrome was assessed using a hydrogen breath test with lactulose on the LactophaH2 apparatus of AMA (St. Petersburg). Intestinal dysbiosis was determined by plating feces on nutrient media. Bile acids in bile were determined on the AmazonX mass spectrometer (Bruker Daltonik GmbH, Bremen, Germany). Ultrasound examination of the abdominal cavity performed with the apparatus «SHIMADZU SDN-500» (Japan). Liver elastography was performed using the AIXPLORER apparatus (France).Results. The syndrome of intestinal bacterial overgrowth in 67% of cases was established in the presence of ileocecal insufficiency, in 33% of cases — with preserved ileocecal function. The combination of intestinal bacterial overgrowth syndrome and intestinal dysbiosis was detected in 81,8% of patients. The majority of the examined patients showed clinical symptoms of damage the hepatobiliary system and intestines, which was confirmed by change laboratory parameters — increase the level of total cholesterol, markers of cholestasis and cytolysis compared with the control group. In the study of bile acids in bile, decrease free (mainlycholic) and increase conjugated (glycodesoxycholic, taurodesoxycholic, glycocholic, taurocholic) bile acids was observed compared with the control group. In general, patients with the syndrome of intestinal bacterial overgrowth revealed the presence of non-calculous cholecystitis — in 11,5% of cases, I stage of cholelithiasis — in 25,7%, II stage of cholelithiasis — in 18,9%, non-alcoholic fatty liver disease on stage steatosis and steatohepatitis — in 43,9% of cases.Conclusion. Intestinal bacterial overgrowth syndrome is the beginning of bacterial translocation, which is the triggering factor in inflammation of the liver and biliary tract. In turn, diseases of the hepatobiliary system contribute to the development of intestinal dysbiosis by reducing the synthesis of bile acids with antibacterial action, as well as violations of their excretion. Thus, strong association of intestinal bacterial overgrowth syndrome with damage to the hepatobiliary system has been established.

La diversidad en los antropónimos de los peruanos
Authors: Rojas Salazar Marcelino 
Published: February 2019

El Perú tiene una población de 31 237 000 habitantes, según los resultados del último Censo Nacional ejecutado por el Instituto Nacional de Estadística e Informática (INEI)en 2017. El 49,2% son hombres y el 50,8% son mujeres. El territorio peruano posee una riqueza cultural tanto en la arquitectura, la escultura, la pintura, la música, ladanza, la gastronomía, la literatura y la lingüística. Este último aspecto se refiere a la diversidad de lenguas que se consideran idiomas en el país. Así, cada lengua poseesu propia estructura fonológica, morfológica y sintáctica, además, de su propio sistema de antroponimia. Desde los últimos 25 años, los peruanos inscriben los nombresy apellidos de sus hijos mediante el organismo público llamado Registro Nacional de Identificación y Estado Civil (Reniec), que se encarga de la identificación y entrega deldocumento nacional de identidad (DNI). Por otra parte, ocurre una situación en la cual los padres registran a los futuros ciudadanos del país con nombres motivados por lamoda e influenciados por la televisión, la música, un evento cívico, la política, el deporte o el cine; o sea, se van dejando de lado los nombres de los abuelos, de los tíos, del santoy patrón del pueblo o de los mismos padres como fuente de inspiración para registrar a sus hijos. Sin embargo, esta libre elección por nombres supeditados a la moda puede traer consecuencias en el proceso de desarrollo de la autoestima del niño, debido a que existen nombres que poseen una carga semántica belicosa, agresiva e iracunda en la sociedad. Por ello, los padres deben considerar esta situación para evitar futuros conflictos emocionales.
Violencia, poder y obreros en el valle de Chicama (1912)
Authors: Ortiz Díaz María Luz 
Published: February 2019

Esta investigación explora desde un enfoque multidisciplinario los hechos de violencia contra trabajadores rurales acaecidos en abril de 1912 en el valle de Chicama. Dentrodel movimiento obrero constituyó un hecho importante, porque es una organización inicial de protesta colectiva que no ocurrió en la capital sino en una provincia, y que nuestrahistoriografía nacional, que también está centralizada en Lima, no ha investigado con la profundidad que lo amerita. A nivel internacional es también un hito importante, comolo menciona Cesar Lévano, únicamente comparable a la violencia ejercida a las clases subalternas en Colombia con los Bananeros, o con los obreros salitreros de Santa María deIquique en Chile. Hubo un aproximado de 1502 a 5003 jornaleros rurales muertos de los valles del norte.
