Abstract
AbstractMoisture transport during food drying can be phenomenologically described by Fick’s second law and by the so-called anomalous diffusion model. However, in the literature, many studies have shown the extensive use of empirical/semiempirical models (EMs/SEMs) to adjust experimental data for the drying of thin-layer foods. This research aims to perform a critical analysis of the most commonly used EMs/SEMs and compare them with Fick’s second law and an anomalous diffusion model using two different sets of hot-air drying data. Two waste byproducts from the food industry, spent coffee grounds and passion fruit peels, were selected for analysis. The selected EMs/SEMs were found to be mathematically interrelated (i.e., some are a subset of others), and their appropriateness was incorrectly justified mainly by their statistical goodness-of-fit. As shown, it is highly recommended that researchers start analyzing drying data with phenomenological models. The extensive use of EMs and SEMs can be replaced by the anomalous diffusion model, which has a high capacity to adjust empirical data and a sound phenomenological description of the process.

Abstract
Derivatives of 3,9-dimethoxypterocarpan (1, homopterocarpin) were prepared by nitration, amination, and oxidation reactions, among others, and their antifungal activity was evaluated against the phytopathogenic fungi Colletotrichum gloeosporioides and C. lindemuthianum. Derivatives were purified by chromatographic techniques and identified by nuclear magnetic resonance spectroscopy. Eight derivatives were obtained from 1 corresponding to 3,9-dimethoxy-8-nitropterocarpan (2), 3,9-dimethoxy-2,8-dinitropterocarpan (3), 3,9-dimethoxy-2,8,10-trinitropterocarpan (4), 2,8-diamino-3,9-dimethoxypterocarpan (5), 3,9-dimethylcoumestan (6), medicarpin (7), 2'-hydroxy-4-(2-hydroxyethylsulfanyl)-7,4'-dimethoxyisoflavan (8), and 4-(2-hydroxyethylsulfanyl)-7,2',4'-trimethoxyisoflavan (9). The in vitro antifungal activity of the derivatives was determined at concentrations between 35 and 704 μM. Compounds 7 and 8 at 704 μM, showed an inhibition of radial growth and spore germination close to 100%, exceeding that found for the starting compound 1, which was 46%. Growth inhibition assays were also performed for the derivative 8 on papaya fruits (Carica papaya L. cv. Hawaiana) and mango (Mangifera indica L. cv. Hilacha) infected with C. gloeosporioides. Compound 8 showed fungal growth inhibition in fruits higher than that found for 1 and thymol (a recognized natural antifungal), under the same conditions. In general, derivatives that exhibited greater antifungal activity correspond to the compounds containing hydroxyl groups in the structure. Some of the compounds obtained could be considered promising for the control of phytopathogenic fungi.

Abstract
There is a high percentage of error in the approach of patients with joint pain by primary care physicians. An algorithm can help improve this misdiagnosis problem. Our study seeks to determine the effectiveness of an algorithm when used by primary care physicians for the diagnosis of cases of joint pain patients. A randomized clinical experiment was carried out. Primary care physicians from five cities in Colombia developed a series of clinical cases, which were presented to them through a website on their personal cell phones. Half of the doctors developed the cases using the diagnostic algorithm, and the other half developed the cases without the use of the algorithm. Main measures were proportion of correct diagnosis, number, type of laboratory and diagnostic images requested for the diagnostic approach of clinical cases. Two hundred and twenty-four primary care physicians participated. The overall proportion of cases correctly diagnosed was 37.3% higher in the intervention group; we found a greater difference in cases of spondyloarthritis (60.8%), followed by systemic lupus erythematosus with joint involvement (32.2%), rheumatoid arthritis (30.3%) and osteoarthritis (25.9%). The average number of tests requested to develop clinical cases was lower in the intervention group than in the control group, both globally and for each of the four diseases, with statistically significant differences for each of the comparisons. The diagnostic algorithm proved to be an effective tool when used by primary care physicians; the proportion of correct diagnoses increased, and the number of tests requested in the development of the cases decreased.

Abstract
The design and development of gluten-free foods requires a comprehensive understanding of the behavior of the raw materials to attain the same cooking and nutritional quality as gluten-based food. The objective of this study was to determine the optimal hot-air drying conditions for elaboration of cassava flour to be used in a gluten-free pasta formulation. The results showed that the operational conditions to minimize the hot-air drying time (57 min) to produce cassava flour with higher water holding capacity was 57 ℃ at 3 m/s. Then, the optimal formulation for the pasta was found to be cassava (26 g/100 g), amaranth flour (12 g/100 g), and carboxymethyl cellulose (0.23 g/100 g), which maximized the Aw (0.160), moisture content (3.10 g/100 g), hardness (5.02 N), and protein content (9.30 g/100 g), and it is used for the sensorial analysis, which showed that an earthy taste was the main problem with consumer satisfaction.

Abstract
En este estudio se caracterizó la microbiota natural (levaduras y bacterias ácido lácticas) observada durante la fermentación espontánea de variedades de uva de Chile, con el fin de evaluar su potencial para producir vinos con menor contenido de etanol. El potencial de fermentación de las levaduras seleccionadas se determinó en términos de consumo de azúcar y producción de etanol. Las cepas con potencial para producir vinos reducidos en etanol se estudiaron adicionalmente en inoculaciones secuenciales con Saccharomyces cerevisiae. Se identificaron nueve especies no Saccharomyces y solo tres géneros de bacterias ácido lácticas. Durante las etapas finales de fermentación, S. cerevisiae y L. mesenteroides fueron dominantes, mientras que solo Candida, Metchnikowia, Torulaspora y Lachancea spp. se observaron después de 14 días de fermentación. La fermentación de cultivo puro con cepas aisladas seleccionadas mostró aproximadamente un 50% de utilización de azúcar, con una producción de etanol que varió desde 6.25 a 9.25% v/v. Nuestros resultados sugieren que las levaduras nativas R. glutinis, M. pulcherrima y H. uvarum, aisladas en este estudio, son potenciales para producir vinos reducido en etanol. Sin embargo, se necesitan más estudios sobre la contribución en sabor y el aroma.

Abstract
OBJECTIVE To identify ways that provision of hemophilia care can be maximized at the local level, irrespective of available resources or cultural or geographic challenges. METHODS The SHIELD group used its multinational experience to share examples of local initiatives that have been employed to deliver optimal hemophilia care. RESULTS The examples were reviewed and categorized into four key themes: guidelines and algorithms for delivery of care; collaboration with patients and allied groups for care and education; registries for the monitoring of treatment and outcomes and health care planning and delivery; and opportunities for personalization of care. These themes were then incorporated into a road map for collaborative care in hemophilia that reflected the contribution of best practice. DISCUSSION Differing healthcare reimbursement systems, budgetary constraints, and geographical and cultural factors make it difficult for any country to fully deliver ideal care for people with hemophilia. The SHIELD approach for collaborative care provides illustrative examples of how four key themes can be used to optimize hemophilia care in any setting.

Abstract
BACKGROUND Obesity has been associated with reduced dexmedetomidine clearance, suggesting impaired hepatic function or reduced hepatic blood flow. The aim of this study was to clarify the effect of obesity in dexmedetomidine metabolic clearance. METHODS Forty patients, ASA I-III, 18-60 yr old, weighing 47-126 kg, scheduled for abdominal laparoscopic surgery, were enrolled. Anaesthetic agents (propofol, remifentanil, and dexmedetomidine) were dosed based on lean body weight measured by dual X-ray absorptiometry. Serial venous samples were drawn during and after dexmedetomidine infusion. A pharmacokinetic analysis was undertaken using non-linear mixed-effect models. In the modelling approach, the total body weight, lean body weight, and adjusted body weight were first tested as size descriptors for volumes and clearances. Hepatic blood flow, liver histopathology, liver enzymes, and gene expression of metabolic enzymes (UGT2B10 and UGT1A4) were tested as covariates of dexmedetomidine metabolic clearance. A decrease in NONMEM objective function value (ΔOFV) of 3.84 points, for an added parameter, was considered significant at the 0.05 level. RESULTS A total of 637 dexmedetomidine serum samples were obtained. A two-compartmental model scaled to measured lean weight adequately described the dexmedetomidine pharmacokinetics. Liver blood flow was a covariate for dexmedetomidine clearance (ΔOFV=-5.878). Other factors, including fat mass, histopathological damage, and differential expression of enzymes, did not affect the dexmedetomidine clearance in the population studied (ΔOFV<3.84). CONCLUSIONS We did not find a negative influence of obesity in dexmedetomidine clearance when doses were adjusted to lean body weight. Liver blood flow showed a significant effect on dexmedetomidine clearance. CLINICAL TRIAL REGISTRATION NCT02557867.

Abstract
OBJECTIVE To assess the rate of endophthalmitis after intravitreal injection (IVI) in a «clean room» of a single health centre, following the guidelines of the Spanish Vitreo-Retinal Society (SERV). An analysis was performed on the culture specimens, response to treatment, and final outcomes (guidelines). MATERIAL AND METHODS A retrospective, observational study was conducted on a consecutive case series of patients diagnosed with infectious endophthalmitis after IVI in a single health centre between 2010 and 2015. Intravitreal and systemic treatment was given following the SERV guidelines. The patients were followed up the case was resolved. RESULTS There were 5 cases of endophthalmitis out of 9467 IVI (incidence 0.053%). Positive cultures were obtained in aqueous and/or vitreous fluid in all cases, with Staphylococcus epidermidis being involved in 4 out of 5 cases. In 2 cases, final visual acuity was non-light perception due to intractable retinal detachments after resolution of the infectious process. CONCLUSIONS IVI performed in a «clean room» have a low incidence of endophthalmitis. The most common infectious agent was Staphylococcus species. In 2 cases the functional prognosis was poor.

Abstract
Abstract
Background: The role of the HER2-enriched (HER2E) subtype determined by the Prosigna Assay in the neoadjuvant setting has remained largely uncharacterized. In this study, we examine whether Prosigna can identify a subgroup of HER2+ patients for whom combination neoadjuvant therapy that includes trastuzumab (Herceptin) is associated with a greater likelihood of pathological complete response (pCR). Methods: In this single-arm retrospective analysis, 75 patients determined to be HER2+ by IHC were treated with a neoadjuvant regimen (NAC) consisting of 8-12 cycles of anthracyclines and taxanes as well as Herceptin. The Prosigna Assay was performed on the NanoString nCounter® Dx Analysis System at HU Virgende la Victoria de Málaga/CIMES-UMA. pCR was used as the endpoint for this study and was determined using the Miller & Payne scoring criteria. Results: Mean patient age for this study population was 49 (±11.1yr) and all patients were determined to be HER2+ by IHC. The overall pCR rate in this patient population was 46.2%. Of the 75 patient samples analyzed for this study, 59 (78.6%) were HER2E, 4 (5.3%) were Luminal A and 12 (16.1%) were Luminal B, as identified by the Prosigna Assay. Of the 16 tumors classified as Luminal (A or B) by Prosigna within this HER2+ population, only 2 (12.5%) responders were observed. Categorical analysis revealed that Prosigna subtype predicted response to a NAC regimen combined with Herceptin (Odds ratio [Her2E vs. non-Her2E]=6.4, p=0.023). Further analysis of the Her2E subtype revealed that tumors with profile expression that correlated well with the prototypical Her2E centroid were significantly more likely to respond to combination NAC and Herceptin (Odds ratio [Unit increase of 1 in Her2E correlation]=88.2, p=0.004). Conclusions: The results of this study indicate that HER2+ patients with greater correlations to the HER2E subtype have an increased likelihood of response to combination neoadjuvant regimens that included HER2-targeted therapy.

Abstract
BACKGROUND The EUROCARE study collects and analyses survival data from population-based cancer registries (CRs) in Europe in order to provide data on between-country differences in survival and time trends in survival. METHODS This study analyses data on liver cancer, gallbladder and extrahepatic biliary tract cancers ("biliary tract cancers"), and pancreatic cancer diagnosed in 2000-2007 from 88 CRs in 29 countries. Relative survival (RS) was estimated overall, by region, sex, age and period of diagnosis using the complete approach. Time trends in 5-year RS over 1999-2007 were also analysed using the period approach. RESULTS The prognosis of the studied cancers was poor. Age-standardised 5-year RS was 12% for liver cancer, 17% for biliary tract cancers and 7% for pancreatic cancer. There were some between-country differences in survival. In general, RS was low in Eastern Europe and high in Central and Southern Europe. For all sites, 5-year RS was similar in men and women and decreased with advancing age. No substantial changes in survival were reported for pancreatic cancer over the period 1999-2007. On average, there was a crude increase in 5-year RS of 3 percentage points between the periods 1999-2001 and 2005-2007 for liver cancer and biliary tract cancers. CONCLUSIONS The major changes in imaging techniques over the study period for the diagnosis of the three studied cancers did not result in an improvement in the prognosis of these cancers. In the near future, new innovative treatments might be the best way to improve the prognosis in these cancers.

Abstract
We generalize Morita's works [J. Phys. A 7, 289 (1974); J. Phys. A 7, 1613 (1974)] on ground states of Ising chains, for chains with a periodic structure and different spins, to any interaction order. The main assumption is translational invariance. The length of the irreducible blocks is a multiple of the period of the chain. If there is parity invariance, it restricts the length in general only in the diatomic case. There are degenerated states and under certain circumstances there could be nonregular ground states. We illustrate the results and give the ground state diagrams in several cases.

Abstract
OBJECTIVE The significance of detecting herpes simplex virus (HSV) DNA in the cerebrospinal fluid (CSF) of infants with HSV encephalitis after receipt of prolonged therapy with high-dose (60 mg kg(-1) day(-1)) acyclovir is unknown. We report the clinical and laboratory characteristics, neuroimaging studies and outcomes of four neonates with HSV encephalitis who had persistence of CSF HSV DNA, by polymerase chain reaction (PCR) after 15 to 21 days of high-dose acyclovir therapy. STUDY DESIGN Retrospective chart review. RESULTS All four infants had abnormal neuroimaging studies and subsequently experienced severe developmental delay or death. CONCLUSION A persistently positive CSF HSV PCR in neonates may be another risk factor for worse neurodevelopmental outcome. Prospective studies are needed to document how often HSV DNA persists in CSF, elucidate whether it represents an initially high CSF viral load, ongoing viral replication or viral resistance, and determine its possible association with neurodevelopmental impairment.

Abstract
The identification of human artifacts at the early archaeological site of Monte Verde in southern Chile has raised questions of when and how people reached the tip of South America without leaving much other evidence in the New World. Remains of nine species of marine algae were recovered from hearths and other features at Monte Verde II, an upper occupational layer, and were directly dated between 14,220 and 13,980 calendar years before the present ( approximately 12,310 and 12,290 carbon-14 years ago). These findings support the archaeological interpretation of the site and indicate that the site's inhabitants used seaweed from distant beaches and estuarine environments for food and medicine. These data are consistent with the ideas that an early settlement of South America was along the Pacific coast and that seaweeds were important to the diet and health of early humans in the Americas.

Abstract
The aim of this study was to evaluate the impact on initial graft function of the degree of steatosis detected in the back-table biopsy, and its repercussion on the clinical results of the transplant (early posttransplant mortality and morbidity). We undertook a retrospective analysis of 300 liver transplants performed at our center from 1997 to 2004. A wedge liver biopsy was done routinely during back-table surgery (available in 294 transplants). The degree of steatosis was classified as: S0-no steatosis, 201 transplants; S1-mild steatosis (<30%), 58 transplants; S2-moderate steatosis (30% to 60%), 18 transplants; and S3-severe steatosis (>60%), 17 transplants. The ischemia-reperfusion (I/R) injury, based on the maximum mean peak aspartate transferase in the first 72 posttransplant hours, tended to be greater as the degree of graft steatosis increased: S0, 1316; S1, 1985; S2, 2446; and S3, 2955 (P < .005 between S0 and S3). This greater initial hepatic dysfunction was correlated in the group with severe steatosis with a higher rate of severe renal failure requiring hemofiltration/hemodialysis: S0, 9%; S1, 15%; S2, 11%; and S3, 41% (P < .001); as well as with a higher early mortality (90 days): S0, 10%; S1, 21%; S2, 11%; and S3, 41% (P < .001). The Kaplan-Meier survival curve showed a significant difference (log-rank and Breslow) between the group with severe steatosis and the group with no steatosis (P = .002). We conclude that the degree of liver graft steatosis is an important determinant of I/R injury, although this progressive increase in the I/R injury with the degree of steatosis only had clinical repercussions in the case of severe steatosis.

Abstract
INTRODUCTION Liver transplantation is currently the best therapeutic option for small hepatocellular carcinoma (HC) in selected cirrhotic patients. The main aim of this study was to analyze the results of a recent series of liver transplant cirrhotic patients with small HC applying strict preoperative selection criteria. PATIENTS AND METHODS During a period of 6 years we performed 53 liver transplants with a final diagnosis of HC on cirrhosis. The selection criteria for liver transplantation (LT) by modern imaging techniques were the Milan criteria (TNM I and II of the modified classification). RESULTS Of the 53 patients, 44 (83%) were transplanted with preoperatively known HC, and 9 (17%) with incidental HC. The mean time on the waiting list was 74 +/- 62 days. Despite using strict selection criteria, 23 patients (43%) exceeded the Milan criteria in the specimen and 17 (32%) even exceeded the extended criteria of the UCSF. With a mean follow-up of 2 years, only two patients have developed recurrences. The overall survival at 1, 3, and 5 years was 80%, 70%, and 70%, respectively. The survival of patients that exceeded the Milan or USF criteria at 1, 3, and 5 years was 72% and 76%; 67% and 69%; 67% and 69%, respectively. CONCLUSIONS The results of liver transplantation for HC are excellent when applying strict preoperative selection criteria. The current imaging methods lead to a considerable infrastaging percentage (30% to 40%), extending the indications for liver transplant due to HC beyond the scope that clinical reports would justify.

Abstract
BACKGROUND AND OBJECTIVES Plasma exchange with fresh-frozen plasma (FFP) is the treatment of choice in thrombotic thrombocytopenic purpura (TTP). Methylene blue-photoinactivated plasma (MBPIP) has been proposed as a safer alternative to FFP, but its effectiveness in the treatment of TTP is not well established. The purpose of this study was to investigate whether MBPIP is as effective as FFP in the treatment of TTP by plasma exchange. MATERIALS AND METHODS A retrospective analysis was carried out of 56 TTP episodes, occurring between 1990 and 2003, which had been treated by plasma exchange. MBPIP was used for fluid replacement in 27 episodes and FFP in 29. The effect of plasma (MBPIP or FFP) on treatment outcomes was analysed by multivariate logistic regression. RESULTS Compared to patients treated with FFP, those receiving MBPIP had an increased risk of dying from progressive TTP [adjusted odds ratio (OR) = 31; 95% confidence interval (CI): 1.2 to > 100], a greater number of recurrences while on plasma exchange therapy (OR = 4.6; 95% CI: 1.2-17), and a lower probability of attaining a sustained remission within 9 days of starting plasma exchange (OR = 5.2; 95% CI: 1.3-20). CONCLUSIONS MBPIP seems to be less effective than FFP in the treatment of TTP. It is therefore prudent to avoid MBPIP until therapeutic equivalency to FFP has been established by randomized, controlled trials.

Abstract
Acute dysfunction of cardiac allograft without evidence of cellular rejection is a potentially fatal complication of heart transplantation that suggests a humoral origin. In clinical practice, humoral rejection (HR) is suspected when there is evidence of severe allograft dysfunction but endomyocardial biopsy (EMB) shows no evidence of cellular rejection. Between April 1991 and August 2003, 12 patients (2.74%) among 438 heart transplants displayed this condition. Time post-heart transplant (HT) was 21.3 +/- 24.7 months (range 2 to 72 months). Immunofluorescence studies using classic markers were negative. All patients were treated with methylprednisolone "bolus" and plasmapheresis until clinical recovery, after which their immunosuppressive regimens were modified. Eleven of the 12 patients recovered satisfactory allograft function. In this series the incidence of suspected HR was low. Unlike other studies, we observed HR not only soon but also even years after HT. Plasmapheresis seems to be an effective treatment.

Abstract
We describe priority issues and some of the results obtained from the implementation of the Prevention and Reduction of Traffic Accident Injuries program in a health area. Since 1999 the public health center has made a priority of identifying and recruiting partners from other sectors (the local police association and the local education authority), increasing its capacity for working together, and setting up an intersectorial working group. Teaching activities and meetings were held. A network of people was created from 17 of a total of 39 town halls that participate in activities supported by the intersectorial group. Ten are involved in educational activities and a further seven focus on ensuring compliance with the law. The intersectorial group promoted their visibility through the local media. These activities are not aimed at reducing injuries from road traffic accidents, but rather at creating an action framework through which all the sectors involved can be mobilized. The aim is to strengthen commitment among political, technical and civil sectors by focussing on social values of respect for a healthier life.

Abstract
The simulation of hydrodynamics and transport phenomena in waste stabilization ponds is a developing tool worth studying in order to understand their internal processes and interactions. Pond design involves several physical, hydrological, geometric and dynamic variables so as to provide high hydrodynamic efficiency and maximum substrate utilization rates. CFD modelling allows the combination of these factors to predict the behaviour of ponds having different configurations. The two-dimensional depth-integrated model MIKE 21 was used in this study to simulate hydrodynamic and advection-dispersion processes in a full-scale anaerobic pond (AP) located in southwest Colombia. A set of 12 configurations including sludge contents, inlet-outlet positioning, baffling and pond geometry were modelled. Results showed that a crosswise (diagonally opposite) inlet-outlet layout, a length-to-breadth ratio of 2:1, plus provision of two cross baffles at 1/3 L and 2/3 L were the most effective measures to improve overall AP hydrodynamics and dispersion patterns.
