Abstract
PURPOSE Salvage surgery is mandatory when regional persistence/recurrence after chemoradiation. The aim of this study is to describe the outcomes of salvage surgery. METHODS A retrospective study was conducted in patients with locally advanced head and neck squamous cell carcinoma that were primarily treated with chemorradiation and underwent salvage neck dissection (ND) with suspected recurrent/persistent nodal disease. All patients had a response evaluation at 12 weeks through clinical examination and computed tomography-positron emission tomography. Decision for ND was taken in case of suspected persistence or if there was suspicion of recurrence, histologically confirmed. RESULTS There were 40 patients included. 32/40 (80%) ND were done because of confirmed/suspected persistence and 8/40 (20%) were done because of recurrences. Persistence was confirmed histologically in 14/32 (43.8%) cases and recurrence in 6/8 (75%) cases. Median survival from diagnosis was 39 months (95% CI 28.162-49.838). Significant differences were observed between patients who had viable tumour cells in the sample and those who did not, but the differences were only significant when only deaths due to tumour progression were considered (p = 0.014). 14/32 (43.8%) patients with suspected or confirmed persistence developed a recurrence after the ND and 3/8 (37.5%) patients with suspected or confirmed recurrence developed a new recurrence. New recurrences were more frequent in cases that had viable tumor in the specimen. CONCLUSIONS Patients with nodal persistence/recurrence have a poor prognosis, even after salvage surgery. However, in a substantial number of patients the disease is controlled after ND, so it should be offer to these patients.

Abstract
This work employed a two-step biorefining process, consisting of a hemicellulose-rich liquor production through ultrasound-assisted cold alkaline extraction (CAE), followed by thermochemical treatment of the resultant solid phase. The post-CAE solid phase's pyrolytic potential was assessed by application of thermogravimetric analysis (TGA) and Friedman's isoconversional method, and also from hydrogen production. The solid phases remaining after the CAE treatment were more reactive than the untreated raw material. Notably, the alkali concentration employed in the first step was the individual variable most pronounced influence on their activation energy (Ea). Thus, at a degree of conversion α = 0.50, Ea ranged from 109.7 to 254.3 kJ/mol for the solid phases, compared to 177 kJ/mol for the raw material; this value decreased with rising glucan content. At maximal degradation, the post-CAE solid phases produced up to 15.57% v/v more hydrogen than did the untreated raw material.

Abstract
BACKGROUND The purpose of this study was to evaluate p16, p53, EGFR, pEGFR protein expression and HPV infection as possible markers of tumor progression in a series of sinonasal inverted papilloma (SNIP) and sinonasal squamous cell carcinoma (SNSCC). METHODS A series of 49 SNIP, 11 SNSCC associated with SNIP (SNIP-SNSCC) and 52 SNSCC not associated with SNIP were analyzed for p16, p53, EGFR, and phosphorylated EGFR (pEGFR) expression by immunohistochemistry. Human papillomavirus (HPV) infection status was evaluated by DNA-PCR. Results were correlated to clinical and follow-up data. RESULTS Reduced or loss of p16 expression was observed in 18% SNIP, 64% SNIP-SNSCC and 87% of SNSCC. Reduced or loss p16 staining in SNIP correlated with shorter recurrent SNIP-free follow-up. In contrast, p16 expression was not predictive of recurrent SNSCC in cases with SNIP-SNSCC and SNSCC. P53, EGFR, and pEGFR expression did not differ between the tumor groups, nor were they related to recurrent SNIP-free follow-up or recurrent SNSCC. Oncogenic HPV types 16 and 18 were detected in 5% of SNIP and 18% of SNIP-SNSCC, but not in SNSCC. There was no correlation between HPV infection and >70% p16 immunostaining. CONCLUSIONS HPV infection appears to play a minor role in SNIP and SNSCC and p16 immunostaining does not appear a valid surrogate marker for HPV. However, reduced or loss p16 expression may have prognostic value as a risk marker for recurrent SNIP.

Abstract
BACKGROUND AND AIMS Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures. METHODS Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator. RESULTS A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity. CONCLUSIONS This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement.

Abstract
The results reported by different studies on telemonitoring in patients with chronic obstructive pulmonary disease (COPD) have been contradictory, without showing clear benefits to date. The objective of this study was to ascertain whether an early discharge and home hospitalization telehealth program for patients with COPD exacerbation is as effective as and more efficient than a traditional early discharge and home hospitalization program. A prospective experimental non-inferiority study, randomized into two groups (telemedicine/control) was conducted. The telemedicine group underwent monitoring and was required to transmit data on vital constants and ECGs twice per day, with a subsequent telephone call and 2 home visits by healthcare staff (intermediate and at discharge). The control group received daily visits. The main variable was time until first exacerbation. The secondary variables were: number of exacerbations; use of healthcare resources; satisfaction; quality of life; anxiety-depression; and therapeutic adherence, measured at one and 6 months of hospital discharge. A total of 116 patients were randomized (58 to each group) without significant differences in baseline characteristics or time until first exacerbation, i.e. median 48 days (pp. 25-75:23-120) in the control group, and 47 days (pp. 25-75:19-102) in the intervention group; p = 0.52). A significant decrease in the number of visits was observed in the intervention versus the control group, 3.8 ± 1 vs 5.1 ± 2(p = 0.001), without significant differences in the number of exacerbations. In conclusion follow-up via a telemedicine program in early discharge after hospitalization is as effective as conventional home follow up, being the cost of either strategy not significantly different.

Abstract
Deer antlers can be used as an index of individual performance both in ecological and productive contexts. Their quality is often measured only by their biometrical features, such as size, asymmetry or weight. Mechanic characteristics cannot normally be measured without destroying the antler and hence losing the commercial value of the trophies. Here, we studied ultrasonic velocities, density, and tensile strength across various sections of cast antlers of Iberian red deer (Cervus elaphus hispanicus). We found that the speed value depended on the section of the antler and the propagation direction. For antler sections, velocities were lowest for mid–beam and highest for brow tine. Results were similar for density and indirect tensile strength, probably related to differences in functionality among antler sections. Density explained most of the variability of ultrasound–speed. The time elapsed from antler shed affected density more than ultrasound speed. The indirect tensile strength showed a non–linear, decelerating relationship with ultrasound speed. We discuss the applications of ultrasound speed as a non–invasive tool to measure density and physical properties of antlers and antler sections, and their potential use as an index of quality.

Abstract
We present an analytical model for the role of hydrogen bonding on the spin-orbit coupling of a model DNA molecule. Here, we analyze in detail the electric fields due to the polarization of the hydrogen bond on the DNA base pairs and derive, within a tight binding analytical band folding approach, an intrinsic Rashba coupling which should dictate the order of the spin active effects in the chiral-induced spin selectivity effect. The coupling found is ten times larger than the intrinsic coupling estimated previously and points out to the predominant role of hydrogen bonding in addition to chirality in the case of biological molecules. We expect similar dominant effects in oligopeptides, where the chiral structure is supported by hydrogen-bonding and bears on orbital carrying transport electrons.

Abstract
INTRODUCTION The short-term results of endoscopic treatment of vesicoureteral reflux (VUR) are excellent. Over time, however, a number of patients have been identified for whom VUR reappeared after being resolved with this technique. The aim of this study was to analyse the factors related to this event. MATERIAL AND METHODS A retrospective, analytical, case-control study included 395 ureteral units with primary VUR treated successfully at our centre, with a minimum follow-up of 3 years. We identified cases in which VUR reappeared and analysed the demographic variables, those related to VUR (grade, laterality, initial study) and those related to the operation (materials used). RESULTS We identified 77 ureteral units with recurrence in the 395 included units (19.5%). The recurrence rate was 29.7% for the patients treated with dextranomer/hyaluronic acid (Dx/HA), 20.2% for those treated with polydimethylsiloxane (MP) and 12.2% for polytetrafluoroethylene (PTFE). The onset of recurrence rose to 35% for patients treated before 1 year of age and those with gradeV VUR. Urinary dysfunction symptoms also increased the recurrence rate to 34.9%. CONCLUSION The use of resorbable dextranomer/hyaluronic acid material was related to recurrence in the endoscopic treatment of VUR. The high-grade reflux and treatment at an early age, as well as the presence of urinary dysfunction, are also factors associated with recurrence.

Abstract
Currently, treatment for acute rhinitis (AR) is symptomatic but no clear agreement exists to control its development. Propolis extract may appear as a promising natural treatment for AR, but its beneficial effects have not yet been fully tested. Forty children suffering from AR and common cold symptoms aged between 2-12 years were enrolled in a prospective epidemiological multicentre study. A 7-day treatment with propolis nasal spray (3 times/day) was applied and a comparison of symptomatology, subjective global improvement and quality of life (QoL) between baseline (day 1) and final (day 7) visits were performed. The main goal was to evaluate the changes in symptom intensity using the Jacksons scoring test. After 7 days of treatment there was a significant decrease of symptoms both in the total score (p less than 0.0001) and in regard to each AR symptom (p less than 0.01). On the whole, the sample reported no symptoms by day 7, and the resolution of symptoms occurred approximately at day 4. Furthermore, there was no need for supplementary treatment. Both the subjective global improvement impression and the QoL of patients appeared to significantly improve after treatment. No adverse events (AEs) were found globally. It can be concluded that propolis nasal spray effectively improves recovery from infectious AR and common cold symptoms in children and is an optimal alternative in the treatment of this disease without need for any adjuvant treatment.

Abstract
Cacao from South America is especially used to produce premium quality chocolate. Although the European Food Safety Authority has not established a limit for cadmium (Cd) in chocolate raw material, recent studies demonstrate that Cd concentrations in cacao beans can reach levels higher than the legal limits for dark chocolate (0.8 mg kg-1, effective January 1st, 2019). Despite the fact that the presence of Cd in agricultural soils is related to contamination by fertilizers, other potential sources must be considered in Ecuador. This field study was conducted to investigate Cd content in soils and cacao cultivated on Ecuadorian farms in areas impacted by oil activities. Soils, cacao leaves, and pod husks were collected from 31 farms in the northern Amazon and Pacific coastal regions exposed to oil production and refining and compared to two control areas. Human gastric bioaccessibility was determined in raw cacao beans and cacao liquor samples in order to assess potential health risks involved. Our results show that topsoils (0-20 cm) have higher Cd concentrations than deeper layers, exceeding the Ecuadorian legislation limit in 39% of the sampling sites. Cacao leaves accumulate more Cd than pod husks or beans but, nevertheless, 50% of the sampled beans have Cd contents above 0.8 mg kg-1. Root-to-cacao transfer seems to be the main pathway of Cd uptake, which is not only regulated by physico-chemical soil properties but also agricultural practices. Additionally, natural Cd enrichment by volcanic inputs must not be neglected. Finally, Cd in cacao trees cannot be considered as a tracer of oil activities. Assuming that total Cd content and its bioaccessible fraction (up to 90%) in cacao beans and liquor is directly linked to those in chocolate, the health risk associated with Cd exposure varies from low to moderate.

Abstract
We investigated whether apoptotic spermatocytes from the mouse Mus m. domesticus presented alterations in chromosomal synapses and DNA repair. To enrich for apoptotic spermatocytes, the scrotum's temperature was raised by partially exposing animals for 15 min to a 42ºC water bath. Spermatocytes in initial apoptosis were identified in situ by detecting activated Caspase-9. SYCP1 and SYCP3 were markers for evaluating synapses or the structure of synaptonemal complexes and Rad51 and γH2AX for detecting DNA repair and chromatin remodeling. Apoptotic spermatocytes were concentrated in spermatogenic cycle stages III-IV (50.3%), XI-XII (44.1%) and IX-X (4.2%). Among apoptotic spermatocytes, 48% were in middle pachytene, 44% in metaphase and 6% in diplotene. Moreover, apoptotic spermatocytes showed several structural anomalies in autosomal bivalents, including splitting of chromosomal axes and partial asynapses between homologous chromosomes. gH2AX and Rad51 were atypically distributed during pachytene and as late as diplotene and associated with asynaptic chromatin, single chromosome axes or discontinuous chromosome axes. Among apoptotic spermatocytes at pachytene, 70% showed changes in the structure of synapses, 67% showed changes in gH2AX and Rad51 distribution and 50% shared alterations in both synapses and DNA repair. Our results showed that apoptotic spermatocytes from Mus m. domesticus contain a high frequency of alterations in chromosomal synapses and in the recruitment and distribution of DNA repair proteins. Together, these observations suggest that these alterations may have been detected by meiotic checkpoints triggering apoptosis.

Abstract
BACKGROUND Everolimus (EVL)-based immunosuppressive strategies may permit the reduction of calcineurin inhibitors (CNI) and their side effects, while offering a safe and efficient treatment. Our aim was to describe our experience with EVL in everyday practice and provide information for its optimal utilization. METHODS Prospective, multicenter study of 181 kidney transplant recipients treated with EVL as part of their immunosuppressive regimen, with a follow-up of 24 months. We studied demographic data, transplant characteristics, clinical information, drugs used, serum creatinine, estimated glomerular filtration rate (eGFR), rejection episodes, and adverse events. RESULTS In total, 181 renal transplant recipients were included. Of these, 30 (16.6%) received EVL de novo and 151 (83.4%) were converted; median time from transplantation to conversion was 10 (range, 1-312) months. Main reasons for conversion were prevention of interstitial fibrosis and tubular atrophy (23.9%), intolerance to immunosuppressants (11.1%), neoplasia (13.9%), nephrotoxicity (8.9%), and cytomegalovirus infections (8.3%). The eGFR values at baseline, months 12, and 24 were 46.4 ± 27.4 mL/min, 54.8 ± 22.9 mL/min, and 55.9 ± 26.5 ml/min, respectively. Two of 181 (1.1%) patients died, 5 of 181 (2.8%) lost their grafts, 12 of 181 (6.6%) had an episode of acute rejection, 13 of 181 (7.2%) had ≥1 serious event and infection, and 85 of 181 (49.9%) had ≥1 nonserious adverse event or infection. Multivariate analysis showed that increased eGFR at month 24 was associated with lower donor age, shorter time from transplant to EVL introduction, and a baseline eGFR ≥40 mL/min. CONCLUSION Through different strategies among centers, the inclusion of EVL improved renal function during the first 12 months.

Abstract
Orujo is a traditional alcoholic beverage produced in Galicia (northwest Spain) from distillation of grape pomace, a byproduct of the winemaking industry. In this study, the effect of the distillation system (copper charentais alembic versus packed column) and the yeast strain (native yeast L1 versus commercial yeast L2) on the chemical and sensory characteristics of orujo obtained from Albariño (Vitis vinifera L.) grape pomace has been analyzed. Principal component analysis, with two components explaining 74% of the variance, is able to clearly differentiate the distillates according to distillation system and yeast strain. Principal component 1, mainly defined by C6-C12 esters, isoamyl octanoate, and methanol, differentiates L1 from L2 distillates. In turn, principal component 2, mainly defined by linear alcohols, linalool, and 1-hexenol, differentiates alembic from packed column distillates. In addition, an aroma descriptive test reveals that the distillate obtained with a packed column from a pomace fermented with L1 presented the highest positive general impression, which is associated with the highest fruity and smallest solvent aroma scores. Moreover, chemical analysis shows that use of a packed column increases average ethanol recovery by 12%, increases the concentration of C6-C12 esters by 25%, and reduces the concentration of higher alcohols by 21%. In turn, L2 yeast obtained lower scores in the alembic distillates aroma profile. In addition, with L1, 9% higher ethanol yields were achieved, and L2 distillates contained 34%-40% more methanol than L1 distillates.

Abstract
Lignocellulosic material from Leucaena leucocephala was subjected to a two-stage fractionation process to obtain a valorized effluent containing hemicellulose derivatives and a solid phase for producing cellulose pulp by conventional soda-anthraquinone delignification. This solid phase allows the production of cellulose pulp, under less rigorous conditions from NaOH-AQ process (177 °C, 21%, 120 min) than without pretreatment delignification (185 °C, 25%, 150 min) and better or similar properties in the paper sheets obtained (yield 27.6 and 34.0%, brightness 39.3 and 31.6% ISO, tensile index 7.8 and 10.5 N m/g, burst index 0.43 and 0.29 MPa m(2)/kg with and without previous autohydrolysis) have be found. Also, the first autohydrolysis stage allows up to 46.6% of the initial hemicellulose in the raw material to be extracted as xylooligomers, xylose and furfural into the liquid phase.

Abstract
Animal and plant ecologists generally follow separate paths. This often leads to disjointed approaches to solving similar ecological problems. In the past 20 years, two related, but unconnected, research fields have undergone rapid development: modular demography, with its morphological and functional analysis of resource capture, until now basically the domain of plant ecology; and foraging theory, traditionally applied and developed in animal ecology. The results of recent research on the foraging strategies of ants and clonal plants, however, outline a general framework of functional parallels between both types of organisms that could link important aspects of animal and plant foraging ecology.

Abstract
A commercial variety of Leucaena leucocephala K360 was used for pulp production and papermaking employing the soda-anthraquinone process. Also, the chemical and energy contents of the resultant black liquors were determined to simultaneously optimize: pulp and paper production and energy generation. A process temperature of (185°C), an operating time of (120 min) and an active alkali concentration of (21%) provided sheets of paper with good strength (tensile index of 12.12 Nm/g, burst index of 0.38 kPa m(2)/g, tear index of 1.29 mN m(2)/g and a Kappa number of 20.5) and black liquor with a greater calorific value (14.1 MJ/kg) than that obtained with higher active alkali concentrations. However, reducing the active alkali concentration to a level in the low operation range led to less marked degradation of cellulose and allowed paper sheets with good properties to be obtained and energy to be optimally produced from the black liquor.
