Abstract
Pig homogeneity and growth are major concerns for the pig industry today. Variability in pigs' size has a strong impact on profitability as uniformity plays a key role in the overall economic value of pigs produced. This research focused on statistical methods to identify pigs at risk of growth retardation at different stages of production. Data from 125 083 Yorkshire pigs at weaning (18-28 d), 59 533 pigs at the end of the nursery period (70-82 d) and 48 862 pigs at slaughter (155-170 d) were analyzed under three different cut-points (lowest 10, 20 and 30%) to characterize light animals. Records were randomly split into 2:1 training:testing sets, and each training data set was analyzed through an ordinary least squares approach and four machine learning algorithms (decision tree, random forest, and two alternative boosting approaches). A wide range of weighting functions were applied to give increased relevance to lighter pigs. Each resulting classification norm was used to classify light pigs in the testing data set. Both sensitivity and specificity were retained to construct the receiver operating characteristic curve, and the statistical performance of each analytical approach was evaluated by the area under the curve (AUC). In all production stages and cut-points, the random forest machine learning algorithm provided the highest AUC, closely followed by boosting procedures. For weaning BW (WW), factors related to birth BW and litter size accounted for more than 75% of the important prediction factors for light pigs. BW at the end of the nursery period and slaughter BW analyses revealed a similar pattern where WW and BW at the end of the nursery period accounted for more than 40 and 50% of statistical importance among the prediction factors, respectively. Machine learning algorithms are useful tools to easily evaluate the risk factors affecting the efficiency and homogeneity in swine. Since the BW at birth and weaning are key factors, sow nutrition and feeding management during gestation and lactation, along with piglet management during lactation, are identified as important influences on pig weight variability.

Abstract
BACKGROUND Beyond programmed death-ligand 1 (PD-L1) assessed by the combined positive score (CPS) and tumor mutational burden (TMB), no other biomarkers are approved for immunotherapy interventions. Here, we investigated whether additional clinical and pathological variables may impact on immunotherapy outcomes in recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients. METHODS R/M HNSCC patients treated with immunotherapy were reviewed. Analyzed variables at baseline included: clinicopathological, laboratory, and variables reflecting the host nutritional status such as the prognostic nutritional index (PNI) and albumin. The primary endpoint was progression free survival (PFS). The secondary endpoints were overall survival (OS) and objective response rate (ORR). Univariable and multivariable Cox models were fitted and random forest algorithm was used to estimate the importance of each prognostic variable. RESULTS A total of 100 patients were treated with immunotherapy; 50% with single agent and 50% with experimental immunotherapy combinations. In the multivariable analysis, both ECOG performance status (HR: 1.73; 95%CI 1.07-2.82; p = 0.03) and PNI levels (10-point increments, HR: 0.66; 0.46-0.95; p = 0.03) were significantly associated with PFS. However, the derived neutrophil to lymphocyte ratio (dNLR) and lactate dehydrogenase (LDH) were not significantly associated with PFS (p-values > 0.15). In the OS analysis, albumin and PNI were the only statistically significant factors in the multivariable model (p < 0.001). CONCLUSIONS In our cohort, PNI and ECOG performance status were most strongly associated with PFS in R/M HNSCC patients treated with immunotherapy. These results suggest that parameters informative of nutritional status should be considered before immunotherapy.

Abstract
BACKGROUND AND OBJECTIVE A long-term tracheostomy can have significant negative effects on quality of life because it causes physical, functional, sensory, psychological, social, economic, and work impairments to the life of the individual. The objective of this study was to validate in Spanish a quality-of-life questionnaire for these patients. MATERIALS AND METHODS A psychometric validation study of a questionnaire in 45 patients over 18 years of age, with tracheostomy for six months, who understand Spanish and have a good understanding of the questions of the SF-36 questionnaire and a specific quality of life questionnaire for the patient with tracheostomy (TQOL-versión española). This Vquestionnaire is a modification and cultural adaptation into Spanish of the original English instrument named Tracheostomy Specific Quality of Life Questionnaire (TQOL). The two questionnaires (TQOL-versión española) and the SF-36 were completed 6 months after the tracheostomy and between 30 and 50 days after the first administration. The reliability, repeatability, and construct validity of the TQOL-versión española were evaluated. The construct validity was assessed by the correlation between the results of the TQOL-versión española and the dimensions of the SF-36 questionnaire. RESULTS The reliability of the TQOL-versión española measured by Cronbach's alpha coefficient was .814, with variation between items from .783 to .817 in the sample at 6 months and from .794 in the validation sample, with variation between items from .758 to .813. There was intraclass correlation for the total score of the scale using the concordance analysis of Bland-Altman and agreement for the individual questions with the McNemar symmetry test. There was also a good correlation between the scales of the TQOL-versión española and the dimensions of the S-F36. CONCLUSIONS The TQOL-versión española showed good reliability, repeatability, and construct validity, therefore it is a useful tool to assess the impact on individual patients with a tracheostomy in place for more than 6 months, and to establish strategies at the healthcare and social levels to improve the quality of daily life.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is diagnosed based on the clinical signs, but its presentation is heterogeneous and potentially confounded by concurrent conditions, such as obesity and insulin resistance. miRNA have recently emerged as putative pathophysiological and diagnostic factors in PCOS. However, no reliable miRNA-based method for molecular diagnosis of PCOS has been reported. The aim of this study was to develop a tool for accurate diagnosis of PCOS by targeted miRNA profiling of plasma samples, defined on the basis of unbiased biomarker-finding analyses and biostatistical tools. METHODS A case-control PCOS cohort was cross-sectionally studied, including 170 women classified into four groups: non-PCOS/lean, non-PCOS/obese, PCOS/lean, and PCOS/obese women. High-throughput miRNA analyses were performed in plasma, using NanoString technology and a 800 human miRNA panel, followed by targeted quantitative real-timePCR validation. Statistics were applied to define optimal normalization methods, identify deregulated biomarker miRNAs, and build classification algorithms, considering PCOS and obesity as major categories. RESULTS The geometric mean of circulating hsa-miR-103a-3p, hsa-miR-125a-5p, and hsa-miR-1976, selected among 125 unchanged miRNAs, was defined as optimal reference for internal normalization (named mR3-method). Ten miRNAs were identified and validated after mR3-normalization as differentially expressed across the groups. Multinomial least absolute shrinkage and selection operator regression and decision-tree models were built to reliably discriminate PCOS vs non-PCOS, either in obese or non-obese women, using subsets of these miRNAs as performers. CONCLUSIONS We define herein a robust method for molecular classification of PCOS based on unbiased identification of miRNA biomarkers and decision-tree protocols. This method allows not only reliable diagnosis of non-obese women with PCOS but also discrimination between PCOS and obesity. CAPSULE We define a novel protocol, based on plasma miRNA profiling, for molecular diagnosis of PCOS. This tool not only allows proper discrimination of the condition in non-obese women but also permits distinction between PCOS and obesity, which often display overlapping clinical presentations.

Abstract
Simple Summary Drug resistance is the principal limiting factor to achieving good survival rates in patients with cancer. The identification of potential biomarkers for diagnosis and prognostic prediction, as well as the design of new molecular-targeted treatments, will be essential to improving head and neck squamous cell carcinoma (HNSCC) patient outcomes. In this sense, the sensitization of resistant cells and cancer stem cells (CSCs) represents a major challenge in cancer therapy. We conducted a proteomic study involving cisplatin-resistance and CSCs with the aim to unravel the molecular and cellular mechanisms by which tumor cells acquire resistance to chemotherapy. Syntenin-1 (SDCBP) was identified as an important protein involved in the chemoresistance and stemness of HNSCC tumors. Abstract To characterize the mechanisms that govern chemoresistance, we performed a comparative proteomic study analyzing head and neck squamous cell carcinoma (HNSCC) cells: CCL-138 (parental), CCL-138-R (cisplatin-resistant), and cancer stem cells (CSCs). Syntenin-1 (SDCBP) was upregulated in CCL-138-R cells and CSCs over parental cells. SDCBP depletion sensitized biopsy-derived and established HNSCC cell lines to cisplatin (CDDP) and reduced CSC markers, Src activation being the main SDCBP downstream target. In mice, SDCBP-depleted cells formed tumors with decreased mitosis, Ki-67 positivity, and metastasis over controls. Moreover, the fusocellular pattern of CCL-138-R cell-derived tumors reverted to a more epithelial morphology upon SDCBP silencing. Importantly, SDCBP expression was associated with Src activation, poor differentiated tumor grade, advanced tumor stage, and shorter survival rates in a series of 382 HNSCC patients. Our results reveal that SDCBP might be a promising therapeutic target for effectively eliminating CSCs and CDDP resistance.

Abstract
6081 Background: Treatment selection based on actionable alterations (AAs) is an appealing strategy for pts with R/M SGT. The GEMS-001 study (NCT02069730) at Princess Margaret Cancer Centre (PM) and the Vall D´Hebron Institute of Oncology (VHIO) pre-screening program facilitate the identification of AAs for R/M SGT pts and treatment selection. Methods: We analyzed R/M SGT treated at PM and VHIO from 2015 to 2020. Clinicopathological features, molecular alterations and treatment modalities were correlated with outcomes. The primary endpoint was overall response rate (ORR) by RECIST 1.1. Clinical benefit rate (CBR) was defined by pts with partial response or stable disease ≥4 months. Clinical actionability of multigene panel testing (NGS) and immunohistochemistry (IHC) were assessed as per institutional molecular tumor boards or investigators. Pts were opportunistically matched to available therapies from each center. Results: In total 206 pts were enrolled. On IHC, HER2 overexpression was present in 9%, Androgen Receptor (AR) 33%, Estrogen/Progesterone Receptor (ER/PR) 11% and ALK overexpression 0%. On NGS, PIK3CA mutation (mut) was in 9%, NTRK fusion 6%, NOTCH1-3 mut 5%, HRAS mut 6%, ERBB2/3 alterations (alt) 4% and FGFR1-4 alt 3%. Up to 92 pts (45%) displayed at least 1 AA and 36 pts (18%) had ≥2 AAs. A total of 60 pts (29%) were matched to AAs. Of those matched, median age was 60 years (range 33-84), M:F 21:39, 95% ECOG≤1 with a median number of prior treatment lines 0 (range 0-3), and their AAs included 26 AR, 9 HER2 or ERBB2 overexpression, 9 PIK3CA mut, 3 NTRK fusion, 3 FGFR1-3 alt and 10 other AAs (2 ER/PR overexpression, 2 EGFR mut, 1 c-kit mut, 1 BAP1 mut, 1 Non-V600 BRAF mut, 1 CDKN2A mut, 1 CHEK2 mut and 1 PTCH1 mut). Overall, ORR was 27% for the matched population. See table for outcomes. Conclusions: In our cohort, almost one third of the population received therapies matched to AAs. Our results suggest that targeted therapies have promising activity in pts with R/M SGT supporting comprehensive molecular and IHC profiling in treatment determination.[Table: see text]

Abstract
HIV represents a persistent infection which negatively alters the immune system. New tools to reinvigorate different immune cell populations to impact HIV are needed. Herein, a novel nanotool for the specific enhancement of the natural killer (NK) immune response towards HIV-infected T-cells has been developed. Bispecific Au nanoparticles (BiAb-AuNPs), dually conjugated with IgG anti-HIVgp120 and IgG anti-human CD16 antibodies, were generated by a new controlled, linker-free and cooperative conjugation method promoting the ordered distribution and segregation of antibodies in domains. The cooperatively-adsorbed antibodies fully retained the capabilities to recognize their cognate antigen and were able to significantly enhance cell-to-cell contact between HIV-expressing cells and NK cells. As a consequence, the BiAb-AuNPs triggered a potent cytotoxic response against HIV-infected cells in blood and human tonsil explants. Remarkably, the BiAb-AuNPs were able to significantly reduce latent HIV infection after viral reactivation in a primary cell model of HIV latency. This novel molecularly-targeted strategy using a bispecific nanotool to enhance the immune system represents a new approximation with potential applications beyond HIV.

Abstract
Simple Summary Therapy resistance in head and neck squamous cell carcinoma (HNSCC) patients is the main obstacle to achieve more effective treatments that improve survival and quality of life of these patients. Therefore, it is of vital importance to unravel the molecular and cellular mechanisms by which tumor cells acquire resistance to chemotherapy. We conducted a comparative proteomic study involving cisplatin-resistant cells and cancer stem cells with the aim of identifying proteins potentially implicated in the acquisition of cisplatin resistance. Through this study, we identified for the first time tetraspanin-1 (TSPAN1) as an important protein involved in the development, progression and chemoresistance of HNSCC tumors. Abstract Sensitization of resistant cells and cancer stem cells (CSCs) represents a major challenge in cancer therapy. A proteomic study revealed tetraspanin-1 (TSPAN1) as a protein involved in acquisition of cisplatin (CDDP) resistance (Data are available via ProteomeXchange with identifier PXD020159). TSPAN1 was found to increase in CDDP-resistant cells, CSCs and biopsies from head and neck squamous cell carcinoma (HNSCC) patients. TSPAN1 depletion in parental and CDDP-resistant HNSCC cells reduced cell proliferation, induced apoptosis, decreased autophagy, sensitized to chemotherapeutic agents and inhibited several signaling cascades, with phospho-SRC inhibition being a major common target. Moreover, TSPAN1 depletion in vivo decreased the size and proliferation of parental and CDDP-resistant tumors and reduced metastatic spreading. Notably, CDDP-resistant tumors showed epithelial–mesenchymal transition (EMT) features that disappeared upon TSPAN1 inhibition, suggesting a link of TSPAN1 with EMT and metastasis. Immunohistochemical analysis of HNSCC specimens further revealed that TSPAN1 expression was correlated with phospho-SRC (pSRC), and inversely with E-cadherin, thus reinforcing TSPAN1 association with EMT. Overall, TSPAN1 emerges as a novel oncogenic protein and a promising target for HNSCC therapy.

Abstract
Advances in immunotherapy have achieved remarkable clinical outcomes in tumors with low curability, but their effects are limited, and increasing evidence has implicated tumoral and non-tumoral components of the tumor microenvironment as critical mediators of cancer progression. At the same time, the clinical successes achieved with minimally invasive and optically-guided surgery and image-guided and ablative radiation strategies have been successfully implemented in clinical care. More effective, localized and safer treatments have fueled strong research interest in radioimmunotherapy, which has shown the potential immunomodulatory effects of ionizing radiation. However, increasingly more observations suggest that immunosuppressive changes, metabolic remodeling, and angiogenic responses in the local tumor microenvironment play a central role in tumor recurrence. In this review, we address challenges to identify responders vs. non-responders to the immune checkpoint blockade, discuss recent developments in combinations of immunotherapy and radiotherapy for clinical evaluation, and consider the clinical impact of immunosuppressive changes in the tumor microenvironment in the context of surgery and radiation. Since the therapy-induced modulation of the tumor microenvironment presents a multiplicity of forms, we propose that overcoming microenvironment related resistance can become clinically relevant and represents a novel strategy to optimize treatment immunogenicity and improve patient outcome.

Abstract
To identify the putative relevance of autophagy in laryngeal cancer, we performed an immunohistochemistry study to analyze the expression of the proteins involved in this process, namely, LC3, ATG5 and p62/SQSTM1. Additionally, Prostate tumor-overexpressed gene 1 protein (PTOV1) was included due to its potential relevance in laryngeal cancer. Moreover, as cancer resistance might involve autophagy in some circumstances, we studied the intrinsic drug resistance capacity of primary tumor cultures derived from 13 laryngeal cancer biopsies and their expression levels of LC3, ATG5, p62 and PTOV1. Overall, our results suggest that (i) cytoplasmic p62 and PTOV1 can be considered prognostic markers in laryngeal cancer, (ii) the acquisition of resistance seems to be related to PTOV1 and autophagy-related protein overexpression, (iii) by increasing autophagy, PTOV1 might contribute to resistance in this model and (iv) the expression of autophagy-related proteins could classify a subgroup of laryngeal cancer patients who will benefit from a therapy based upon autophagy inhibition. Our study suggests that autophagy inhibition with hydroxychloroquine could be a promising strategy for laryngeal cancer patients, particularly those patients with high resistance to the CDDP treatment that in addition have autophagy upregulation.

Abstract
The purpose of this study was to evaluate the effect of two doses of D-chiro-inositol (DCI) in combination with Myo-inositol (MYO) in women with PCOS undergoing ICSI. This was a multicenter controlled, randomized, double-blind parallel group study with two MYO-DCI formulations for 12 weeks. The study group (SG) was administered 550 mg of MYO + 150 mg of DCI twice daily; the control group (CG) was administered 550 mg of MYO + 13.8 mg of DCI twice daily. The participants comprised 60 women with PCOS undergoing ICSI. At baseline, no differences were found between the two groups regarding age, BMI, HOMA-IR or testosterone levels. The pregnancy and live birth rates were significantly higher in the SG than in the CG (65.5 vs. 25.9 and 55.2 vs. 14.8, respectively) [risk ratio (RR) = 0.4; 95%CI (0.2, 0.79); p = .003 and RR = 0.27; 95%CI (0.10, 0.70); p = .002 respectively]. The risk of ovarian hyperstimulation syndrome (OHSS) was lower in the SG (3.44 vs. 18.5%, p = .07). The combination of MYO-DCI at high doses of DCI improves the pregnancy rates and reduces the risk of OHSS in women with PCOS undergoing ICSI.

Abstract
BACKGROUND Although considerable progress has been made in the last 30 years in the treatment of cleft palate (CP), a multidisciplinary approach combining examinations by a paediatrician, maxillofacial surgeon, otolaryngologist and speech and language pathologist followed by surgical operation is still required. In this work, we performed an observational cross-sectional study to determine whether the CP grade or number of ventilation tubes received was associated with tympanic membrane abnormalities, hearing loss or speech outcomes. METHODS Otologic, audiometric, tympanometric and speech evaluations were performed in a cohort of 121 patients (children > 6 years) who underwent an operation for CP at the Vall d'Hebron Hospital, Barcelona from 2000 to 2014. RESULTS The most and least frequent CP types evaluated according to the Veau grade were type III (55.37%) and I (8.26%), respectively. A normal appearance of the membrane was observed in 58% individuals, of whom 55% never underwent ventilation ear tube insertion. No statistically significant associations were identified between the CP type and number of surgeries for insertion of tubes (p = 0.820). The degree of hearing loss (p = 0.616), maximum impedance (p = 0.800) and tympanic membrane abnormalities indicative of chronic otitis media (COM) (p = 0.505) among examined patients revealed no statistically significant association with the grade of CP. However, an association was identified between hypernasality and the grade of CP (p = 0.053), COM (p = 0.000), hearing loss (p = 0.000) and number of inserted ventilation tubes. CONCLUSION Although the placement of tympanic ventilation tubes has been accompanied by an increased rate of COM, it is still important to assess whether this is a result of the number of ventilation tubes inserted or it is intrinsic to the natural history of middle ear inflammatory disease of such patients. Our results do not support improvements in speech, hearing, or tympanic membrane abnormalities with more aggressive management of COM with tympanostomy tubes.

Abstract
Objectives To assess the efficacy and safety of fluocinolone acetonide 0.025%
otic solution versus placebo in treating patients with otic
eczema. Methods In this multicentre, randomized, double-blind, parallel-group phase
3 clinical trial, conducted at 12 Spanish centres between March
2012 and March 2013, patients received fluocinolone acetonide
0.025% or placebo otic solution twice daily for 7 days (days
1–7) with an 8-day follow-up (days 9–15). Outcome measures
included change in itching from baseline (day 1) to study days
4–8 and 9–15, and change in otoscopic signs (erythema, oedema,
and scaling) from baseline to the end of treatment (day 8) and
end of follow-up (day 15). Results Patients treated with fluocinolone acetonide 0.025% (n = 66), as
compared with placebo-treated patients (n = 69), showed
significantly higher reductions in itching from baseline to
study days 4–8 and 9–15, and in individual and global otoscopic
signs from baseline to the end of treatment (day 8) and end of
follow-up (day 15). Incidence and severity of adverse events was
similar between the fluocinolone and placebo groups. Conclusions Fluocinolone acetonide 0.025% otic solution, administered twice
daily for 7 days, is an effective and safe treatment for otic
eczema.

Abstract
6031 Background: Multiple genomic alterations were described in HNC, including squamous cell carcinomas (SCC), salivary gland (SG) and nasopharyngeal (NF) tumors. Tumor molecular profiling (TMP) may increase therapeutic alternatives in early trials for pts with refractory metastatic (met) HNC. We evaluate the impact of matched/unmatched therapy (mT/uT) in HNC with potentially targetable alterations. Methods: From 2010-16, 47 met HNC pts were treated in 57 early trials after TMP. Clinical benefit was measured by: time to progression (TTP); clinical benefit rate (CBR: complete response [CR], partial response [PR] and stable disease [SD] > 4months [m]); progression-free survival [PFS] ratio≥1.3 (PFS under molecular therapeutics/PFS upon last prior chemotherapy [pT]). Results: Median age was 51 years; median number of pT lines was 1 (0-5). In total, 26 SCC, 11 SG, 8 NF and 2 nasosinusal pts (mostly with lymph nodes and lung met) were treated with small kinases (SK) inhibitors (inh) (50%; main targets PI3K/HER/FGFR), immune-oncology (IO) drugs (40%, PD-1/PD-L1), angiogenesis inh (5%) or chaperone, cytidine analog, RNA polymerase (5%). 14/57 trials were mT including CDKinh (1 CDKN2A mutation [mut]), PI3Kinh (5 PIK3CA mut, 2 PTEN mut), PI3K/MEKinh (1 NRAS mut), HERinh (1 ERBB3mut), FGFRinh (2 FGFR1mRNA high, 1 FGF3/4/19 ligand amplified) and porcupine inh (1 ZNFR3mut). Distribution by tumor: IO (16 SCC/5 NF), SKmT (8SG/4SCC/2NF) and SKuT (9SCC/4SG). Responses: 1CR in SCC (IO), 5 PR in SCC (4 IO, 1 FGFRinh), 3 PR in NF (1 cytidin analog, 1 IO, 1 PI3K/MEKinh). Benefit: median TTP 9.33m (CI95% 7-20) with upward trend in NF and SG vs SCC (HR 0.6;p = 0.28), without differences according to target therapies (HR 0.8; p = 0.9); CBR of 58%, without differences by tumor type (p = 0.42) or therapy (SKmT, SKuT, IO; p = 0.5); 60% with PFS ratio≥1.3, significantly higher in SCC and SG (p = 0.016), particularly with IO drug and SKmT, respectively. Conclusions: Considering our preselected fit population as bias selection, individualized treatment selection with novel therapeutics based on TMP, especially in NF and SG irrespective of targets (SKmT, SKuT, IO), and in SCC with IO drugs, seems to confer substantial clinical benefit.

Abstract
In wild-type cells, autophagy represents a tumour-suppressor mechanism, and dysfunction of the autophagy machinery increases genomic instability, DNA damage, oxidative stress and stem/progenitor expansion, which are events associated with cancer onset. Autophagy occurs at a basal level in all cells depending on cell type and cellular microenvironment. However, the role of autophagy in cancer is diverse and can promote different outcomes even in a single tumour. For example, in hypoxic tumour regions, autophagy emerges as a protective mechanism and allows cancer cell survival. By contrast, in cancer cells surrounding the tumour mass, the induction of autophagy by radio- or chemotherapy promotes cell death and significantly reduces the tumour mass. Importantly, inhibition of autophagy compromises tumorigenesis by mechanisms that are not entirely understood. The aim of this review is to explain the apparently contradictory role of autophagy as a mechanism that both promotes and inhibits tumorigenesis using different models. The induction/inhibition of autophagy as a mechanism for cancer treatment is also discussed.

Abstract
The study of cancer stem cells (CSCs) has shown that tumors are driven by a subpopulation of self-renewing CSCs that retain the capacity to engender the various differentiated cell populations that form tumors. The characterization of CSCs has indicated that CSCs are remarkably resistant to conventional radio- and chemo-therapy. Clinically, the remaining populations of CSC are responsible for metastasis and recurrence in patients with cancer, which can lead to the disease becoming chronic and incurable. Therefore, the elimination of CSCs is an important goal of cancer treatments. Furthermore, CSCs are subject to strong regulation by the surrounding microenvironment, which also impacts tumor responses. In this review, we discuss the mechanisms by which pathways that are defective in CSCs influence ultimately therapeutic and clinical outcomes.

Abstract
Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns that are similar to those in humans with obstructive sleep apnea syndrome (OSAS). The objectives of this multicenter prospective study were to assess the effects of surgical correction on clinical signs in dogs with brachycephalic airway obstructive syndrome (BAOS) and to evaluate the levels of several biomarkers [C-reactive protein (CRP); haptoglobin (Hp), and cardiac troponin I (cTnI)] used to determine systemic inflammation and myocardial damage. This study was conducted on 33 dogs with BAOS that were evaluated before and 1 to 2 mo after surgical correction. Palatoplasty was carried out by means of 2 different surgical techniques: carbon dioxide (CO2) laser (n = 12) and electrical scalpel (n = 21). Biomarker levels (CRP, Hp, and cTnI) were determined before and after surgery. There was a significant reduction in respiratory and gastrointestinal signs in dogs with BAOS after surgical treatment (P < 0.001). A greater reduction in respiratory signs (P < 0.002) was obtained using the CO2 laser. No statistical differences were found between CRP and cTnI levels, either before or after surgical correction. Haptoglobin concentration did increase significantly in the postsurgical period (P < 0.008). Surgical treatment in dogs with BAOS reduces clinical signs, regardless of the anatomical components present. Surgical treatment for BAOS is not useful to reduce CRP and Hp levels, probably because BAOS does not induce as obvious an inflammatory process in dogs as in human patients with OSAS. No reduction in cTnI levels was observed 1 mo after surgery in dogs with BAOS, which suggests that some degree of myocardial damage remains.

Abstract
Several epidemiological studies have shown that the outbreaks of Saharan dust over southern European countries can cause negative health effects. The reasons for the increased toxicity of airborne particles during dust storms remain to be understood although the presence of biogenic factors carried by dust particles and the interaction between dust and man-made air pollution have been hypothesized as possible causes. Intriguingly, recent findings have also demonstrated that during Saharan dust outbreaks the local man-made particulates can have stronger effects on health than during days without outbreaks. We show that the thinning of the mixing layer (ML) during Saharan dust outbreaks, systematically described here for the first time, can trigger the observed higher toxicity of ambient local air. The mixing layer height (MLH) progressively reduced with increasing intensity of dust outbreaks thus causing a progressive accumulation of anthropogenic pollutants and favouring the formation of new fine particles or specific relevant species likely from condensation of accumulated gaseous precursors on dust particles surface. Overall, statistically significant associations of MLH with all-cause daily mortality were observed. Moreover, as the MLH reduced, the risk of mortality associated with the same concentration of particulate matter increased due to the observed pollutant accumulation. The association of MLH with daily mortality and the effect of ML thinning on particle toxicity exacerbated when Saharan dust outbreaks occurred suggesting a synergic effect of atmospheric pollutants on health which was amplified during dust outbreaks. Moreover, the results may reflect higher toxicity of primary particles which predominate on low MLH days.

Abstract
Background Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns similar to those in humans with obstructive sleep apnea syndrome (OSAS). The objective of this study was to evaluate the correlation between anatomical components, clinical signs and several biomarkers, used to determine systemic inflammation and myocardial damage (C-reactive protein, CRP; Haptoglobin, Hp; cardiac troponin I, cTnI), in dogs with brachycephalic upper airway obstructive syndrome (BAOS). Results Fifty brachycephalic dogs were included in the study and the following information was studied: signalment, clinical signs, thoracic radiographs, blood work, ECG, components of BAOS, and CRP, Hp and cTnI levels. A high proportion of dogs with BAOS (88%) had gastrointestinal signs. The prevalence of anatomic components of BAOS was: elongated soft palate (100%), stenotic nares (96%), everted laryngeal saccules (32%) and tracheal hypoplasia (29.1%). Increased serum levels of biomarkers were found in a variable proportion of dogs: 14% (7/50) had values of CRP > 20 mg/L, 22.9% (11/48) had values of Hp > 3 g/L and 47.8% (22/46) had levels of cTnI > 0.05 ng/dl. Dogs with everted laryngeal saccules had more severe respiratory signs (p<0.02) and higher values of CRP (p<0.044). No other statistical association between biomarkers levels and severity of clinical signs was found. Conclusions According to the low percentage of patients with elevated levels of CRP and Hp, BAOS does not seem to cause an evident systemic inflammatory status. Some degree of myocardial damage may occur in dogs with BAOS that can be detected by cTnI concentration.

Abstract
The objective of the study was to evaluate the clinical features, response to treatment, and long-term outcome of subglottic stenosis (SGS) in a series of patients diagnosed as having Wegener's granulomatosis (WG) at a single institution. Subglottic stenosis developed in 6 out of 51 (11.7%) patients, in four of them in the absence of other features of active disease, and was the symptom that leads to WG diagnosis in three cases. In two cases, SGS began while the patients were receiving systemic immunosuppressive therapy for disease activity involving other sites. PR3-ANCAs were positive in four cases. An urgent tracheostomy was needed in two patients. Four patients achieved SGS clinical remission on standard treatment with glucocorticoids and cyclophosphamide, but three of them experienced repeated local relapses and required additional immunosuppressive therapy and mechanical dilations. In one case, a local relapse was successfully managed with endotracheal dilation of the stenotic segment and intralesional injection of a long-acting corticosteroid plus mechanical dilation of the stenotic segment (ILCD) without adding supplemental immunosuppressant drugs. Two patients with isolated SGS were also successfully managed with ILCD alone and did not require the institution of systemic immunosuppressive therapy. One patient underwent open surgical repair when the disease was under control. Our data suggest that Subglottic stenosis often occurs or progresses independently of other features of active WG, and that ILCD may be a safe alternative to conventional immunosuppressive therapy in patients who develop SGS in the absence of other features of active disease, allowing reducing the treatment-related toxicity.

Abstract
The radioprotective effects of carnosic acid (CA), carnosol (COL), and rosmarinic acid (RO) against chromosomal damage induced by gamma-rays, compared with those of L-ascorbic acid (AA) and the S-containing compound dimethyl sulfoxide (DMSO), were determined by use of the micronucleus test for antimutagenic activity, evaluating the reduction in the frequency of micronuclei (MN) in cytokinesis-blocked cells of human lymphocytes before and after gamma-ray irradiation. With treatment before gamma-irradiation, the most effective compounds were, in order, CA > RO > or = COL > AA > DMSO. The radioprotective effects (antimutagenic) with treatment after gamma-irradiation were lower, and the most effective compounds were CA and COL. RO and AA presented small radioprotective activity, and the sulfur-containing compound DMSO lacked gamma-ray radioprotection capacity. Therefore, CA and COL are the only compounds that showed a significant antimutagenic activity both before and after gamma-irradiation treatments. These results are closely related to those reported by other authors on the antioxidant activity of the same compounds, and the degree of effectiveness depends on their structure. Furthermore, the results for treatments before and after gamma-ray irradiation suggest the existence of different radioprotective mechanisms in each case.

Abstract
Surgical wound infection is one of the most frequent complications in pharyngo-laryngeal external surgery. They are usually polimicro with gram-positive, negative both aerobial and anaerobial microrganisms. The trachea is usually sterile and contamination is due to the intoduction during intubation of germs from the oropharyngeal area. A retrospective study was performed including 40 patients with pharyngo-laryngeal carcinoma. When the tracheostomy was done a culture from the internal trachea wall was obtained for micro study. Only one patient had an sterile culture from the trachea. There were 3 patients with just one microorganism and all the rest had at least two, being mixed aerobial and anaerobial flora the most frequent.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the efficacy of functional septoplasty in a group of patients with septal dysmorphy and obstructive sleep apnea syndrome (OSAS). PATIENTS AND METHOD 34 patients with nasal respiratory insufficiency and chronic snore were included from 1997 to 2003. All of them were diagnosed of OSAS by nocturnal polysomnography (PSG) and of septal dysmorphy by ORL physical examination. Patients were clinically followed-up at 1, 3 and 6 months after surgery. PSG was also evaluated at 6 months postsurgery. RESULTS A significant objective reduction of the apnea-hypopnea index (AHI) (45.8 vs 31.9), severity of OSAS, and minimal mean oxygen saturation (76.4 to 83.1) was found. Moreover, we observed a significant improvement of subjective scales of sleepiness (13 vs 6) and the patients' satisfaction degree (72% of patients improved). CONCLUSIONS Functional septoplasty is an effective treatment in patients with OSAS and septal dysmorphy.

Abstract
An analysis is made of measured ultraviolet erythemal solar radiation (UVER) data recorded during the year 2003 by the networks of the Catalan Weather Service and the Environment Department of Valencia (both on the Spanish Mediterranean coast). Results show a latitudinal variation at sea level, of 3-4% per degree and an increase with altitude of 10% per km. Based on these data the UV Index has been evaluated for the measuring stations. The maximum experimental value of the UV Index was around 9 during the summer, although higher values were recorded at two stations, one at the highest elevation and the other at the lowest latitude. The annual accumulated doses of irradiation on a horizontal plane have been presented as well as the evolution through the year in units of energy, Standard Erythemal Doses and Minimum Erythemal Doses according to different phototypes. Lastly, the UV Index forecast, determined with a multiple scattering radiative transfer model, has been analyzed. Total agreement or only one unit of difference between measured and modelled values was found in 94% of cloud-free cases.

Abstract
Lymphomas of the head and neck arise in lymph nodes and extranodal areas as Waldeyer ring, nasal cavity, thyroid gland and salivary glands. Though anatomically in close proximity, lymphomas presenting at the ENT area have different clinical characteristics if they are Hodgkin or Non-Hodgkin. We included 31 patients with the diagnosis of lymphoma and diagnosed in our Department between 1999 and 2002. We studied all the different variables that differentiate Hodgkin and Non-Hodgkin's lymphoma. Both types of lymphoma usually present as a cervical mass. Non-Hodgkin lymphoma have extranodal involvement more frequently and also a more advance disease at diagnosis. It is important to include the lymphoma in the differential diagnosis of any cervical mass or ENT lesion.

Abstract
The distribution of seven flavonoids, eriocitrin, luteolin 3'-O-beta-d-glucuronide, hesperidin, diosmin, isoscutellarein 7-O-glucoside, hispidulin 7-O-glucoside, and genkwanin, has been studied in Rosmarinus officinalis leaves, flowers, stems, and roots during plant growth. The maximum level reached by luteolin 3'-O-beta-d-glucuronide in leaves during June-August suggests the existence of a delay between the activation of the enzymes involved in the flavanone and flavone biosynthesis. The presence of hesperidin and diosmin in the vascular system is significant, and hesperidin shows even higher levels than the phenolic diterpenes and rosmarinic acid. The distribution of flavonoids observed in R. officinalis suggests a functional and structural relationship between phytoregulators and flavonoids, where flavonoids would be "protectors" of the activity of phytoregulators. A hypothesis for the general pathway of biosynthesis of these compounds in plants of the family Labiatae is proposed.

Abstract
The distribution of six compounds with three different polyphenol skeletons have been studied in Rosmarinus officinalis: phenolic diterpenes (carnosic acid, carnosol, and 12-O-methylcarnosic acid), caffeoyl derivatives (rosmarinic acid), and flavones (isoscutellarein 7-O-glucoside and genkwanin), each showing a characteristic behavior and distribution during the vegetative cycle. Only in leaves were all six compounds present, and the highest accumulation rate was related with the young stages of development. Rosmarinic acid showed the highest concentrations of all the polyphenols in all organs. The distribution of this acid in leaves, flowers, and stems suggests that in the first stages of flower growth, levels were due to in situ biosynthesis, and in the last stages, the contribution of transport phenomena was increased. The antioxidant activity of six extracts with different polyphenolic composition was evaluated in aqueous and lipid systems. The results clearly suggest that rosemary extracts are excellent antioxidants in both aqueous and lipid systems.

Abstract
The quantitative distribution of flavan-3-ols was determined using high-performance liquid chromatography in several grape seed extracts (GSEs). In all GSEs, polymers of four or more carbon units were the group of procyanidins present in the highest concentration, the real quantity ranging between 60% and 99.5%. In a previous paper we established a relation between antioxidant and anticlastogenic activity of GSEs. A higher grade of polymerization in GSEs allows the existence of a higher number of conjugated structures and higher antioxidant activity. The radioprotective effects of GSEs with various grades of polymerization were determined by use of the micronucleus test for anticlastogenic activity, evaluating the reduction in the frequency of micronuclei in cytokinesis-blocked cells of human lymphocytes exposed to gamma-rays. The radioprotective efficiency of GSEs was according to their grade of polymerization: GSE3 > GSE2 > GSE1 > dimethylsulfoxide. The higher antioxidant capacity and anticlastogenic activity of GSEs can be explained, structurally, by the high number of conjugated structures between the catechol groups in the B-rings and the 3-OH free groups of the polymeric polyphenolic skeleton and, in addition, by the stability of the aroxyl flavonoid radical generated in the processes.

Abstract
The radioprotective effects of a polyphenolic extract of Olea europaea L. leaves (OL); the flavonoids diosmin and rutin, which are widely used as pharmaceuticals; and the sulfur-containing compounds dimethylsulfoxide (DMSO) and 6-n-propyl-2-thiouracil (PTU) were determined by using the micronucleus test for anticlastogenic activity, evaluating the reduction of the frequency of micronucleated polychromatic erythrocytes (MnPCEs) in bone marrow of mouse before and after X-ray irradiation. With treatment before X-irradiation, the most effective compounds were, in order, rutin > DMSO > OL > PTU > diosmin. These results showed, for the polyphenols studied, a linear correlation (r(2) = 0.965) between anticlastogenic activity and antioxidant capacity. The magnitude of protection with treatment after X-irradiation were lower, and the most effective compounds were, in order, OL > diosmin > rutin; DMSO and PTU lacked radioprotective activity. Therefore, OL is the only substance that showed a significant anticlastogenic activity both before and after X-ray irradiation treatments. Structurally, the free oxygen radicals and lipoperoxyradicals scavenging capacity and, consequently, the anticlastogenic activity of these polyphenolic compounds are based principally on the presence of specific functional groups, mainly catechol groups (rutin, oleuropein, hydroxytyrosol, verbascoside, luteolin), that also increase the stability of the aroxyl-polyphenol radical generated in the above processes.

Abstract
The response of B16F10 melanoma and Melan-a melanocyte cell lines to treatment with five polyhydroxylated flavonoids and gallic acid, after 24 and 72 h of exposure, was determined, and the relationship between any antiproliferative effects observed and the chemical structure is discussed. After 24 h, none of the studied compounds showed significant cytotoxic activity in the B16F10 cell line, whereas compounds with an adjacent trihydroxylated substitution pattern did affect the viability of the Melan-a cell line. After 72 h of exposure, myricetin, baicalein and gallic acid significantly inhibited both B16F10 and Melan-a cell cultures, whereas luteolin and quercetin had only a moderate effect. Eriodictyol only had an effect on Melan-a cell viability, which was reduced slightly. These results suggest that the presence of a C2-C3 double bond and three adjacent hydroxyl groups in the flavonoid A- or B-rings confers greater antiproliferative activity to the flavonoid.
