Abstract
BACKGROUND Despite the recognized impact of diet on non-communicable diseases, the association between the Mediterranean diet and periodontal diseases is still uncertain. This study aimed to determine the association between adherence to the Mediterranean Diet Index (MDI) and self-reported gingival health status in Chilean adults, exploring the feasibility of using validated web-based survey questionnaires. METHODOLOGY Cross-sectional data were collected from a representative sample of a population of Chilean adults (18-60 years old) using a low-cost and time-saving methodology. By the PsyToolkit platform, anonymous survey data were downloaded and analyzed in bivariate (crude) and backward stepwise selection multivariate logistic regression models adjusted for sociodemographic determinants, smoking, and dental attendance using STATA 17. Odds ratios (OR) [95% confidence intervals] were estimated. RESULTS In total, 351 complete statistical data were mostly obtained from female university students who had never smoked and reported having visited a dentist in the previous year. Multivariate regression models showed an association between MDI and very good/good gingival health status (OR 1.18 [95% CI 1.04-1.34], p=0.013), absence of bleeding on toothbrushing (OR 1.12 [95% CI 1.01-1.25], p=0.035), and absence of clinical signs of gingival inflammation (OR 1.24 [95% CI 1.10-1.40], p<0.001), after controlling for age, sex, educational level, smoking, and dental attendance. CONCLUSIONS We associated adherence to the Mediterranean diet with better self-reported gingival health status in a population of Chilean adults in an entirely web-based research environment. Longitudinal studies with random sampling are required to establish the effect of diet on gingival and periodontal health. Nevertheless, this evidence could contribute to the design of low-cost surveillance programs to reduce the burden of periodontal disease and related "common risk factors".

Abstract
Giant cell arteritis (GCA), known as temporal arteritis, is a serious condition requiring immediate treatment to prevent complications. GCA can be difficult to diagnose, especially in emergency department (ED) settings where ophthalmology and rheumatology services may be unavailable. Temporal artery ultrasound (TAUS) is a valuable tool for diagnosing GCA. In the ED, TAUS can be used to quickly rule out GCA and avoid unindicated steroid treatment, which can cause serious morbidity in elderly patients. This article discusses the use of TAUS for evaluating patients with suspected GCA in the ED and its potential to expedite treatment and ensure appropriate, timely follow-up for patients with this potential vision and life-threatening condition.

Abstract
OBJECTIVE Emotional dysregulation and irritability are common in individuals with autism spectrum disorder (ASD). We conducted the first meta-analysis assessing the efficacy of a broad range of pharmacological interventions for emotional dysregulation and irritability in ASD and predictors of response. METHOD Following a preregistered protocol (PROSPERO: CRD42021235779), we systematically searched multiple databases until January 1, 2021. We included placebo-controlled randomized controlled trials (RCTs) and evaluated the efficacy of pharmacological interventions and predictors of response for emotional dysregulation and irritability. We assessed heterogeneity using Q statistics and publication bias. We conducted subanalyses and meta-regressions to identify predictors of response. The primary effect size was the standardized mean difference. Quality of studies was assessed using the Cochrane Risk of Bias Tool (RoB2). RESULTS A total of 2,856 individuals with ASD in 45 studies were included, among which 26.7% of RCTs had a high risk of bias. Compared to placebo, antipsychotics (standardized mean difference = 1.028, 95% CI = 0.824-1.232) and medications used to treat attention-deficit/hyperactivity disorder (ADHD) (0.471, 0.061-0.881) were significantly better than placebo in improving emotional dysregulation and irritability, whereas evidence of efficacy was not found for other drug classes (p > .05). Within individual medications, evidence of efficacy was found for aripiprazole (1.179, 0.838-1.520) and risperidone (1.074, 0.818-1.331). Increased rates of comorbid epilepsy (β = -0.049, p = .026) were associated with a lower efficacy. CONCLUSION Some pharmacological interventions (particularly risperidone and aripiprazole) have proved efficacy for short-term treatment of emotional dysregulation and irritability in ASD and should be considered within a multimodal treatment plan, taking into account also the tolerability profile and families' preferences.

Abstract
BACKGROUND The standard treatment of T2-T3ab,N0,M0 rectal cancers is total mesorectal excision (TME) due to the high recurrence rates recorded with local excision. Initial reports of the combination of pre-operative chemoradiotherapy (CRT) and transanal endoscopic microsurgery (TEM) have shown reductions in local recurrence. The TAU-TEM study aims to demonstrate the non-inferiority of local recurrence and the improvement in morbidity achieved with CRT-TEM compared with TME. Here we describe morbidity rates and pathological outcomes. PATIENTS AND METHODS This was a prospective, multicentre, randomised controlled non-inferiority trial including patients with rectal adenocarcinoma staged as T2-T3ab,N0,M0. Patients were randomised to the CRT-TEM or the TME group. Patients included, tolerance of CRT and its adverse effects, surgical complications (Clavien-Dindo and Comprehensive Complication Index classifications) and pathological results (complete response in the CRT-TEM group) were recorded in both groups. Patients attended follow-up controls for local and systemic relapse. TRIAL REGISTRATION NCT01308190. RESULTS From July 2010 to October 2021, 173 patients from 17 Spanish hospitals were included (CRT-TEM: 86, TME: 87). Eleven were excluded after randomisation (CRT-TEM: 5, TME: 6). Modified intention-to-treat analysis thus included 81 patients in each group. There was no mortality after CRT. In the CRT-TEM group, one patient abandoned CRT, 1/81 (1.2%). The CRT-related morbidity rate was 29.6% (24/81). Post-operative morbidity was 17/82 (20.7%) in the CRT-TEM group and 41/81 (50.6%) in the TME group (P < 0.001, 95% confidence interval 42.9% to 16.7%). One patient died in each group (1.2%). Of the 81 patients in the CRT-TEM group who received the allocated treatment, 67 (82.7%) underwent organ preservation. Pathological complete response in the CRT-TEM group was 44.3% (35/79). In the TME group, pN1 were found in 17/81 (21%). CONCLUSION CRT-TEM treatment obtains high pathological complete response rates (44.3%) and a high CRT compliance rate (98.8%). Post-operative complications and hospitalisation rates were significantly lower than those in the TME group. We await the results of the follow-up regarding cancer outcomes and quality of life.

Abstract
Introduction Apical periodontitis (AP) is a common oral disease caused by the inflammatory destruction of the periapical tissues due to the infection of the root canal system of the tooth. It also contributes to systemic bacterial translocation, where peripheric mononuclear blood cells (PBMCs) can act as carriers. Toll-like receptor (TLR) 2 mediates the response to infection and activates inflammatory responses. DNA methylation can be induced by bacteria and contributes to the modulation of this response. Despite the evidence that supports the participation of PBMCs in immune-inflammatory disorders, the inflammatory profile and epigenetic regulatory mechanisms of PBMCs in AP individuals are unknown. Aim To determine TLR2 gene methylation and inflammatory profiles of PBMCs in AP. Methods Cross-sectional exploratory study. Otherwise, healthy individuals with AP (n=27) and controls (n=30) were included. PMBCs were isolated by a Ficoll gradient, cultured for 24 hours, and both RNA and DNA were extracted. DNA was bisulfite-treated, and specific sites at the promoter region of the TLR2 gene were amplified by qPCR using validated primers. To verify its amplification, agarose gels were performed. Then, the PCR product was sequenced. mRNA expression of TLR2 was determined by qPCR. The soluble levels of 105 inflammatory mediators were first explored with Proteome Profiler Human Cytokine Array Kit. Consequently, tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, IL-6Rα, IL-1β, and IL-12p70 levels were measured by Multiplex assay. Results PBMCs from individuals with AP demonstrated a proinflammatory profile showing higher soluble levels of TNF-α, IL-6, and IL-1β compared to controls (p<0.05). Higher TLR2 expression and higher global methylation pattern of the promoter region of the gene were found in AP compared to controls (p<0.05). The CpGs single-sites at positions -166 and -146 were completely methylated, while the site -102 was totally unmethylated, independently of the presence of AP. DNA methylation of CpG single-sites in positions -77 and +24 was positively associated with TLR2 expression. Conclusions PBMCs from AP subjects show a hyperinflammatory phenotype and TLR2 upregulation in association with single CpG-sites’ methylation from the TLR2 gene promoter, thereby contributing to a sustained systemic inflammatory load in individuals with periapical endodontic diseases.

Abstract
This report traces the progressive expansion of health accounts (HA) to measure national health expenditures, from the first attempts in 1926 by the American Medical Association to the present day. Milestones in the development of A System of Health Accounts (SHA) are covered, from the economic background to initial efforts by a few countries and organizations, to the need for a set of accounting standards for health care systems, and finally, to consolidation with SHA 2011. International organizations, such as the World Health Organization, Organization for Economic Cooperation and Development, Eurostat, the World Bank, and the United States Agency for International Development have been critical to expanding national HA exercises and ensuring that these are standardized, comparable, and become institutionalized. National efforts to track health expenditures have not only enriched collective results, but have become an important component of global leadership, informing policy the world over. More than 100 countries have created HA under the global standard and have gained a better understanding of health spending and financial flows. These results are key for monitoring progress toward national and global initiatives, such as the Sustainable Development Goals and Universal Health Coverage. Challenges remain to be tackled, among them institutionalization and quality of results. Social responsibility for improving data sources and expanding the generation and usability of health accounts are also needed.

Abstract
OBJECTIVES Low rates of participation in cancer clinical trials are commonly reported, raising concerns about missed opportunities to engage patients in treatment trials. We reviewed eligibility for and enrollment in pancreatic cancer clinical trials for patients seen at a National Cancer Institute (NCI)-designated cancer center during 1 year, to calculate participation rates with detailed information to determine the best-case participation rate. MATERIALS AND METHODS This retrospective cohort study used the Abramson Cancer Center Cancer Registry, clinical trial protocols, and electronic medical records (EMRs) to determine eligibility for all available pancreatic cancer clinical trials. Patient characteristics and reasons for ineligibility were abstracted from EMRs. We then computed participation rates based on enrollment in trials using EMR and clinical trials monitoring data. RESULTS Of 233 new pancreatic cancer patients in 2014, 47 or 20% enrolled in a clinical trial (enrollment fraction). According to the EMR, of the 66 patients who were eligible for a trial, 54 (82% of eligible) accepted and 47 (71% of eligible) ultimately enrolled in a trial, 8 (12% of eligible) declined, and 4 (6% of eligible) had no record of patient decision. Enrollment in a trial by both the EMR and clinical trials database was confirmed for 71% of eligible patients. CONCLUSIONS This study reveals that 71% of newly diagnosed pancreatic cancer patients who were eligible for a trial were enrolled in a treatment trial. We contend that in-depth analysis, rather than enrollment fraction, should be used to inform the gap between actual participation and optimal clinical trial participation for cancer patients.

Abstract
We describe an experimental system based on optical microscopy, permitting the analysis of the four dimensional structure of the flow inside evaporating sessile droplets by monitoring the motion of tracers in horizontal planes localized at different heights. Inter-plane particle identification is accomplished via 3D tracking algorithms. The multiple plane observation is achieved using a piezoelectric device to make the microscope objective oscillate vertically, while a high-speed camera captures images. The droplet evaporation process lasts several minutes and greatly accelerates as the fluid advances toward complete evaporation. In order to capture the dynamics of the whole process, two cameras with the same optical output but different temporal resolution are used sequentially. Using image processing algorithms, we obtain the full trajectories of multiple tracers, velocities of particles on the free surface of the droplets, and velocity fields. The information available may be used to understand the geometry of the sedimentation pattern.

Abstract
El desarrollo constante de las aplicaciones de comunicación inalámbrica, que se refleja en el creciente número de usuarios y la variedad de dispositivos inalámbricos que son utilizados para aplicaciones diarias, representa una demanda creciente del recurso espectro radioeléctrico. Un ejemplo de esto es el concepto de Internet de las cosas, en inglés Internet of Things (IoT), lo que significa que muchos de los dispositivos utilizados en hogares, oficinas o incluso en lugares públicos se conectan a Internet y entre sí, permitiendo una amplia gama de aplicaciones de telecomunicaciones. Las tecnologías inalámbricas permiten conexiones de forma flexible sin necesidad de redes cableadas, pero a expensas de aumentar el uso del espectro radioeléctrico. Estudios realizados por la Comisión Federal de Comunicaciones de Estados Unidos (FCC) muestran que el uso de bandas de frecuencia no es uniforme y varía dependiendo de la hora del día y la ubicación geográfica. En la hora pico algunas bandas están sobrecargadas mientras que otras permanecen sin ser usadas en toda su capacidad. Por lo tanto, la eficiencia con la que se administra el acceso a este recurso finito es de gran importancia para el futuro y la idea de desarrollar herramientas para un mejor uso del espectro de radio guarda relación con una demanda de uso compleja y en crecimiento. Los avances tecnológicos permiten el desarrollo de sistemas de comunicación con el potencial de utilizar los recursos de radio de una manera más dinámica y eficiente. En este contexto, las técnicas de Radio Cognitiva, en inglés Cognitive Radio (CR) ofrecen una mayor eficiencia y flexibilidad con respecto al uso de este recurso. Este documento presenta los fundamentos sobre CR, sus beneficios y desafíos, información sobre los estándares existentes de los sistemas de CR, así como ejemplos de implementación de estos sistemas.

Abstract
Introduction: Autism spectrum disorder (ASD) is a heterogeneous group of neurodevelopmental disorders with complex multifactorial etiologies. Medical comorbidities are common in ASD and include functional gastrointestinal disorders (fGID), which are reported in 30-70% of patients. In this research study, we aimed to systematically assess the prevalence of gastrointestinal problems in ASD and describe their clinical correlates. Methods: In this retrospective study, we reviewed the medical records of all patients admitted to the Comprehensive Medical Program for ASD (AMITEA) at Gregorio Marañón University General Hospital from January 2012 to December 2015. All patients fulfilled the clinical criteria for ASD (DSM-IV-TR). In addition to fGID, epidemiological and clinical variables were collected at intake. Clinical and demographic features were compared among subjects with and without comorbid gastrointestinal problems. Results: The analyses included all patients with documented information about presence/absence of fGID (n = 845; 95% of patients). Ages ranged from 1 to 53 years (mean = 10.52; SD = 8.92; 80.4% males). At least one fGID was present in 30.5% of patients, constipation being the most prevalent (47.4% of fGID patients); fGID were significantly associated with intellectual disability (ID) (p = 0.017), sleep disorders (p = 0.012), and prescription of psychopharmacological treatment (p = 0.019). Conclusions: Almost one-third of ASD patients in our sample had at least one fGID. The presence of fGID was associated with ID, sleep problems and with behavioral problems (as measured by the prescription of psychotropic drugs). This subsample of ASD patients with fGID deserves particular attention in future research projects, focusing on specific phenotypic characteristics and overlapping biological markers that may underlie both pathologies.

Abstract
This report traces the progressive expansion of health accounts (HA) to measure national health expenditures, from the first attempts in 1926 by the American Medical Association to the present day. Milestones in the development of A System of Health Accounts (SHA) are covered, from the economic background to initial efforts by a few countries and organizations, to the need for a set of accounting standards for health care systems, and finally, to consolidation with SHA 2011. International organizations, such as the World Health Organization, Organization for Economic Cooperation and Development, Eurostat, the World Bank, and the United States Agency for International Development have been critical to expanding national HA exercises and ensuring that these are standardized, comparable, and become institutionalized. National efforts to track health expenditures have not only enriched collective results, but have become an important component of global leadership, informing policy the world over. More than 100 countries have created HA under the global standard and have gained a better understanding of health spending and financial flows. These results are key for monitoring progress toward national and global initiatives, such as the Sustainable Development Goals and Universal Health Coverage. Challenges remain to be tackled, among them institutionalization and quality of results. Social responsibility for improving data sources and expanding the generation and usability of health accounts are also needed.

Abstract
In this work, gold nanoparticles protected by the macrocycle cucurbit[7]uril were used as a catalyst in the reduction of the hazardous antimicrobial nitrofurantoin. 4-Nitrophenol was also employed as the substrate of the reduction for comparative purposes. The kinetic data were modeled to the Langmuir-Hinshelwood equation to know the affinities of the reactants for the surface and the real kinetic constants, a comparison at the molecular level that is made for the first time. From the results, it was observed that the adsorption of nitrofurantoin was stronger than that of 4-nitrophenol whilst the kinetic constant on the surface was higher for 4-nitrophenol than for nitrofurantoin. Additionally, shifts in the nanoparticle surface plasmon band permitted insights to be obtained into the adsorption rate and strength. The reaction induction times were also investigated and were highly dependent on the borohydride concentration and, due to the higher surface affinity of nitrofurantoin compared with 4-nitrophenol, an increase in nitrofurantoin concentration increased the induction time, while a lag phase was not observed for 4-nitrophenol.

Abstract
A divergent selection experiment for intramuscular fat (IMF) of LM at 9 wk of age was performed in rabbits. The objective of this work was to compare the lipid metabolism in muscles and fat tissues of the high-IMF and low-IMF lines. Lipogenic, catabolic, and lipolytic activities were studied in 2 muscles with different oxidative patterns (LM and semimembranosus proprius) and in the perirenal fat depot at 2 ages, 9 and 13 wk. In addition, adipocytes were characterized in perirenal fat. In the fifth generation, direct response to selection was 0.26 g IMF/100 g muscle. Lines showed differences in their lipogenic activities of muscles and fat tissues at 13 wk but not at 9 wk. The high-IMF line showed greater glucose-6-phosphate dehydrogenase (G6PDH), malic enzyme (EM), and fatty acid synthase (FAS) activities in LM than the low-IMF line, with probabilities = 1.00, 0.93, and 0.90, respectively. Differences between lines were particularly great for G6PDH activity, representing 1.13 SD. The high-IMF line also showed greater G6PDH and FAS activities in semimembranosus proprius (P = 0.98 for G6PDH and 0.95 for FAS) and perirenal fat (P = 0.91 for G6PDH and 0.96 for FAS). However, in perirenal fat, EM activity was greater in the low-IMF line (P = 0.90). No differences between lines were found in almost any catabolic or lipolytic activities of muscles. Regarding adipocyte characteristics, the high-IMF line showed larger adipocytes in perirenal fat depot tissue (P = 0.97) compared to the low-IMF line, but no differences between lines were observed in the number of adipocytes. This study sheds light on the metabolic activities involved in the genetic differentiation of lipid deposition in rabbits. This study shows that lipogenic activities in muscles and fat tissues, in particular G6PDH in LM, are involved in the lipid accumulation in muscle and adipose tissues.

Abstract
Itolizumab is a humanized anti-CD6 monoclonal antibody (mAb) that has previously shown encouraging results, in terms of safety and positive clinical effects, in a 6-week monotherapy clinical trial conducted in rheumatoid arthritis (RA) patients. The current Phase I study evaluated the safety and clinical response for a longer treatment of 12 itolizumab intravenous doses in subjects with active RA despite previous disease-modifying anti-rheumatic drug (DMARD) therapy. Twenty-one subjects were enrolled into four dosage groups (0·1, 0·2, 0·4 and 0·8 mg/kg). Efficacy end-points including American College of Rheumatology (ACR)20, ACR50 and ACR70 response rates and disease activity score in 28 joints (DAS28) were monitored at baseline and at specific time-points during a 10-week follow-up period. Itolizumab was well tolerated up to the highest tested dose. No related serious adverse events were reported and most adverse events were mild. Remarkably, itolizumab treatment did not produce lymphopenia and, therefore, was not associated with infections. All patients achieved a clinical response (ACR20) at least once during the study. Eleven subjects (55%) achieved at least a 20% improvement in ACR just 1 week after the first itolizumab administration. The clinical response was observed from the beginning of the treatment and was sustained during 24 weeks. The efficacy profile of this 12-week treatment was similar to that of the previous study (6-week treatment). These results reinforce the safety profile of itolizumab and provide further evidence on the clinical benefit from the use of this anti-CD6 mAb in RA patients.

Abstract
The major infectious diseases in Chile encompass the periodontal diseases, with a combined prevalence that rises up to 90% of the population. Thus, the population-based surveillance of periodontal diseases plays a central role for assessing their prevalence and for planning, implementing, and evaluating preventive and control programs. Self-report questionnaires have been proposed for the surveillance of periodontal diseases in adult populations world-wide.

Abstract
The aim of this study was to (1) optimize a method for the measurement of parabens and phenols in adipose tissue, (2) evaluate the stability of chemical residues in adipose tissue samples, and (3) study correlations of these compounds in urine, serum, and adipose tissue. Samples were obtained from adults undergoing trauma surgery. Nine phenols and seven parabens were determined by isotope diluted TurboFlow-LC-MS/MS. The analytical method showed good accuracy and precision. Limits of detection (LOD) for parabens and phenols ranged from 0.05 to 1.83ng/g tissue. Good recovery rates were found, even when biological samples remained defrosted up to 24h. Benzophenone-3 (BP-3; range of values: <LOD-1.48ng/g tissue) and methylparaben (MeP; <LOD-1.78ng/g tissue) were detected in >70% of adipose tissue samples, while bisphenol-A (BPA; <LOD-3.28ng/g tissue) and 2-phenylphenol (2-PP; <LOD-0.78ng/g tissue) were detected in >40% of adipose tissue samples. In general, levels were similar between adipose tissue and serum, while a correlation between adipose tissue and urine was only found for BP-3. In conclusion, adipose tissue samples in this study were found to contain environmental chemicals considered to be non-persistent, whose levels were weakly or not at all correlated with the urine burden. Therefore, adipose tissue may potentially provide additional information to that obtained from other biological matrices. Further investigations are warranted to explore whether adipose tissue might be a suitable matrix for assessment of the consequences for human health of mid/long-term exposure to these chemicals.

Abstract
BACKGROUND The incidence of perineal hernia after abdominoperineal excision and extralevator abdominoperineal excision ranges from 1 to 26%. In this systematic review, we compared surgical options and postoperative outcomes of perineal hernia repair in this setting from 2012 to 2016 with findings in a review of publications 1944-2011. METHODS We searched the PubMed database using the keywords "hernia" AND "perineum" identified 392 papers published from 1946 to 2016. Two hundred and ninety-six papers published before 2012 were excluded and 96 were found to be potentially relevant. RESULTS Twenty-one studies with a total of 108 patients were included in the final analysis. Perineal hernia repair was performed using the perineal approach in 75 patients (69.44%), the laparoscopic approach in 25 patients (23.14%), the open abdominal approach in three patients (2.77%) and the laparoscopic perineal approach in three patients (2.77%) and the open abdominoperineal approach in two patients (1.8%). Non-absorbable mesh was used in 41 (37.96%) of cases, composite mesh in 20 (18.51%) and biological mesh in 19 (17.59%). Flap reconstruction was used in 25 patients (23.14%). First and second recurrences were observed in 26 (24.07%) and 7 (26.92%) cases, respectively. CONCLUSIONS Comparison of perineal hernia repair from 1944 to 2011 and from 2012 to 2016 showed that perineal and laparoscopic approaches are currently the most commonly used techniques. Primary defect closure was abandoned in favor of synthetic or composite mesh placement. Use of flap reconstruction spread rapidly and the recurrence rate was low. Randomized control trials and a larger sample size are needed to confirm these data and to develop a gold standard treatment for secondary hernia repair after abdominoperineal excision or extralevator abdominoperineal excision.

Abstract
Young rabbits, the dams of which came from a full diallel cross among four maternal lines (A, V, H and LP) and the sires from a single paternal line (R), that produce sixteen genetic groups, was carried out to evaluate the genetic groups and to estimate the crossbreeding genetic parameters of meat quality. The meat quality traits were recorded by NIRS from a sample of 285 longissimus lumborum muscles. Crossbreeding parameters were estimated according to Dickerson model. No differences in protein were found. The line A had significant differences with V line for intramuscular fat, and fatty acids groups. Significant differences for these traits appeared between the crossbred AH and VV (in favor of AH). As conclusion, the significant contrasts between genetic types for chemical composition of the meat are mainly consequence of direct-maternal genetic effects, having grandmaternal and maternal heterosis effects a less relevant role.

Abstract
Intramuscular fat (IMF) is one of the main parameters affecting meat quality. This work analyzes the effect of selection for IMF on sensory attributes and instrumental texture parameters in rabbit meat. A total of 115 rabbits after 6 generations of divergent selection for IMF were slaughtered at 9 or 13 wk (57 and 58 animals, respectively). For each animal, the left longissimus dorsi muscle (LD) was analyzed by near-infrared spectroscopy to measure IMF whereas the right LD was used for the sensory or instrumental texture analysis. Sensory attributes measured were rabbit odor, liver odor, rabbit flavor, liver flavor, aniseed flavor, hardness, juiciness, and fibrousness. The instrumental texture parameters maximum shear force, shear firmness, and total work to cut the sample were measured by a Warner-Bratzler shear test. The line selected for high IMF showed 58% greater IMF than the line selected for low IMF. This divergence affected firmness that was 9.9% greater in the low-IMF line, although no effect was found for the other instrumental texture traits. No effect of selection was observed in any odor or flavor, except for aniseed flavor, which was greater in the high-IMF line than in the low-IMF line. Age had an effect on IMF, instrumental texture parameters, and sensory attributes. Rabbits at 13 wk showed greater IMF and instrumental and sensory hardness and more intense odor and flavor and lower juiciness than rabbits at 9 wk.

Abstract
The CD6 molecule is a pan T cell marker involved in T cell regulation. Although CD6 expression has been correlated with human autoimmune diseases, only a few therapeutic approaches are exploring this molecule as target in the clinic. The biological functions and mechanisms of actions of CD6 have not been definitively established. It is probable that this molecule plays a dual role as a modulator of intracellular signaling. Itolizumab is a humanized monoclonal antibody specific for human CD6, developed at the Center of Molecular Immunology in Havana, Cuba. Its parent murine antibody, the IOR-T1 mAb, had been obtained in the 80's at the Institute of Oncology and Radiology, also in Havana. This article provides an overview of the clinical data obtained in Cuban patients with autoimmune diseases who have been treated with IOR-T1 mAb or itolizumab. Furthermore, we discuss the possible mechanism of action of itolizumab basing the analysis on recent site mutagenesis and structural data, which, contrary to previous interpretations, points to a steric blocking of the CD6-CD166 interaction in the cellular context. Overall, the conducted clinical studies have demonstrated that itolizumab has favorable clinical effects and a safety profile when used as monotherapy in patients with rheumatoid arthritis and psoriasis. So far, in vitro and in vivo evidences indicate that itolizumab has immunomodulatory and anti-inflammatory effects. Hence, itolizumab represents a new therapeutic option for autoimmune diseases such as rheumatoid arthritis and psoriasis.

Abstract
The effects of different cooking techniques on the lipids of pork meat were evaluated. The assayed cooking techniques were deep-frying (DF), shallow-frying (SF), roasting (RO) and boiling (BO). Modi fication of the roasting meat due to reheating in a microwave oven after 24 h at 4 °C (MW), was also studied. In DF and SF significant increases were found in the lipid content (13.7 and 16.7 g/100 g of dry basis, respectively) and in the nun-polar lipids (11.2 and 14.2 g/100 g of dry basis, respectively) due to the absorption of the oil used in these cooking treatments. The main variations in the fatty acid composition of phospholipids and non-polar lipids were observed in the polyunsaturated fatty acid fraction. There was an increase in the content of free fatty acids (SFA, MUFA, PUFA) after MW, BO and RO. By contrast, free fatty acid content in DF and SF was similar to the content of initial raw meat. MW showed the greatest degradation of the phospholipid fraction, with a significant decline in phosphatidyl ethanolamine. All cooking treatments produced an increase in lipid oxidation, this be ing higher in RO and MW treatments.

Abstract
The optimal approach following the isolation of Staphylococcus aureus from an intravascular catheter tip in the absence of concomitant bacteremia remains unclear. We aimed to determine the rate of delayed complications in these patients. We performed a retrospective observational study (during the period 2002-2012) including patients with a catheter tip culture yielding S. aureus. Patients were followed up for ≥6 months. The primary endpoint was the occurrence of delayed staphylococcal complications (either bacteremia and/or metastatic distant infections). A total of 113 patients were included (75 % male, median age 61 years): 46 and 67 with negative and positive blood cultures, respectively. We found a lower rate of delayed staphylococcal complications in cases with no bacteremia within 48 h since catheter removal than in cases of confirmed S. aureus catheter-related bacteremia (0.0 % vs. 25.4 %; p-value < 0.001). In the group without bacteremia, there was a subgroup of 15 patients (32.6 %) who did not receive antimicrobial treatment. Again, delayed complications occurred less commonly in this subgroup of patients without bacteremia (0.0 % vs. 25.4 %; p-value = 0.033). In contrast to patients with S. aureus catheter-related bacteremia, no delayed infectious complications were observed in patients with an isolated catheter tip culture yielding S. aureus and negative blood cultures within 48 h of catheter removal. Futures studies are needed to assess if the therapeutic approach could be different for this group of patients.

Abstract
The objective of this study was to analyse the survival rate and cause of death in children with systemic lupus erythematosus (SLE) during the past 30 years in Chile. A retrospective analysis was performed between 1969 and 2000 on patients attending pediatric rheumatology centres in Santiago, Chile. Survival and causes of death in 31 children followed from 1969 to 1980 fulfilling the 1982 American College of Rheumatology criteria for SLE and treated with oral steroids were compared with 50 other patients who were treated with oral steroids and an aggressive treatment of IV bolus of cyclophosphamide (38 patients) and azathioprine (12 patients). Global survival at five and 10 years follow-up for the patients studied from 1969 to 1980 was 68 and 40%, respectively. During the second study period these values were significantly improved and global survival reached 95% at five years and 90% at 10 years follow-up (P, 0.05). Survival at 10 years follow-up for patients with lupus nephropathy increased from 28% (study period 1964-1980) to 86% (study period 1984-2000). Twelve children died (38%) during the 1964-1980 study period. The causes of death were six due to kidney failure, three due to infectious conditions and another three of unknown causes. During the 1980-2000 study period mortality reached 6% (three cases), two cases died of a lupus flare-up and one case due to infection. In the last three decades, we have seen an important increase in the survival of children with SLE, especially in those patients with renal involvement. Management with immunosuppressive drugs, such as IV cyclophosphamide or azathioprine has changed the prognosis in these children. These results demonstrate that our children with SLE increased their life expectancy but are now faced with new types of morbidity because of the sequelae related to the disease itself.

Abstract
Rheumatoid arthritis is an autoimmune disease characterized by joint inflammation that affects approximately 1% of the general population. Itolizumab, a monoclonal antibody specific for the human CD6 molecule mainly expressed on T lymphocytes, has been shown to inhibit proliferation of T cells and proinflammatory cytokine production in psoriasis patients. We have now assessed the immunological effect of itolizumab in combination with methotrexate in rheumatoid arthritis by analyzing clinical samples taken from 30 patients enrolled in a clinical trial. T and B cell subpopulations were measured at different time points of the study. Plasma cytokine levels and anti-idiotypic antibody response to itolizumab were also evaluated. The combined treatment of itolizumab and methotrexate led to a reduction in the frequency of T cell subpopulations, and plasma levels of proinflammatory cytokines showed a significant decrease up to at least 12 weeks after treatment ended. No anti-idiotypic antibody response was detected. These results support the relevance of the CD6 molecule as a therapeutic target for the treatment of this disease.

Abstract
Background Osteoarthritis of the knee is a major cause of disability among adults. Electro-acupuncture is considered a potentially useful treatment for osteoarthritis. The purpose of this study is to assess the efficacy of electro-acupuncture on pain control, pain perception, plasma cortisol and beta-endorphin levels, patient-perceived quality of life, and pain medication use in patients with chronic knee pain. Methods/design This study is a placebo-controlled, randomized, double-blind, parallel design trial. One hundred sixty out-patients who are more than 50 years old and who have osteoarthritis of the knee will be recruited from the island of Mallorca, Spain. Each participant will be randomly placed into one of two groups: (sham) electro-acupuncture non-insertion technique and real electro-acupuncture. Acupuncture treatments will be the Traditional Chinese Medicine type. The patients will be evaluated after a period of 1 month (with two weekly sessions), 3 months (with one monthly session), 6 months (with one session every 45 days), and 1 year later with follow-up sessions at the end of the study (with one session every 2 months). The primary outcomes will be based on the observed changes from the baseline of the visual analogue scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain measured at 12 weeks after the end of treatment. Also to be included in the study are the possible changes in the secondary efficacy variables from baseline as assessed by the Short Form 36 version 2 health survey (patient-perceived quality of life), patient plasma cortisol and beta-endorphin levels at the different treatment stages, the Goldberg Anxiety and Depression Scale, pain medication use, functional capacity and stiffness (WOMAC subscales), and a VAS. These variables will be assessed at 1 month, 3 months, 6 months, and 1 year after study commencement. Discussion The findings from this study will help to determine whether electro-acupuncture is effective for chronic knee pain management in older people and whether electro-acupuncture can deliver results for the improvement of pain relief, stiffness, and disability. The study will therefore be a major step toward understanding the roles of the hypothalamic-pituitary-adrenal axis and the endogenous opioid system in the effectiveness of electro-acupuncture for chronic pain.

Abstract
Psoriasis is a chronic inflammatory disease with a prevalence of approximately 2-3% in the general population. The majority of diagnosed patients have plaque psoriasis, and about 20% have moderate-to-severe disease. Itolizumab, a new monoclonal antibody specific for the CD6 molecule mainly expressed on T lymphocytes, has demonstrated to inhibit in vitro ligand-induced proliferation and pro-inflammatory cytokine production. We assessed the immunological and histopathological effect of the antibody using clinical samples taken from 26 patients with moderate-to-severe psoriasis included in a clinical trial. The precursor frequency of lymphocytes activated with anti-CD2/CD3/CD28 beads, as well as the number of interferon (IFN)-γ-secreting T cells after stimulation, were measured at different time points of the study. Serum cytokine levels and anti-idiotypic antibody response to itolizumab were also evaluated. Additionally, lymphocyte infiltration and epidermis hyperplasia were studied in five patients. A significant reduction in T cell proliferation capacity and number of IFN-γ-producing T cells was found in treated patients. Serum levels of interleukin-6, tumor necrosis factor and IFN-γ showed an overall trend toward reduction. No anti-idiotypic antibody response was detected. A significant reduction in the epidermis hyperplasia was observed in analyzed patients. These results support the relevance of the CD6 molecule as a therapeutic target for the treatment of this disease.

Abstract
In order to ensure flexibility and rapid new product development, the mold industry made use of soft materials for cavity inserts in injection molds. However, materials of this kind are prone to wear. This article analyzes the topographic characterization of the surface and wear processes in injection molds cavities. Two materials have been used to produce the cavities: aluminum alloy EN AW‐6082 T4 and copper alloy Cu Zn39 Pb3. The surface topography was measured with the use of optical interferometry profiling technology; roughness and surface parameters were determined according to ISO 4287, ISO 25178, and EUR 15178N. In order to complete this research, an experimental part with different thicknesses and shapes was designed, and cavity inserts of aluminum and copper were made. Polyamide PA6, with 30% fiberglass reinforcement, was employed in the experimental procedure. Measurements of cavity mold surfaces were performed after 9,200 cycles on each mold and at different locations on the mold. The surface measurement was made with a white light vertical scanning interferometry, also known as coherence scanning interferometry (ISO DIS 25178‐604). The results are analyzed and differences between the two types of cavity inserts materials are discussed.

Abstract
The aim of this study was to evaluate the selection response on intramuscular fat (IMF) content of LM after 3 generations of divergent selection. Heritability and genetic means for IMF content were also analyzed. Selection was based on the phenotypic value of IMF content measured in 2 full sibs of the first parity. Selection pressure on females was 13% in the base generation and 26% for the next generations. Males were selected within sire families to reduce inbreeding. Line size was 13 males and 83 females in the base population and approximately 8 males and 40 females for high (High) and low (Low)lines in the next generations. A total of 668 records were used to estimate the selection response on IMF. The pedigree file used to estimate heritability and genetic means contained 1,332 animals. Data were analyzed using Bayesian methodology. Differences between lines for IMF were 0.08, 0.10, and 0.09 g/100 g muscle in the first, second, and third generation, respectively. These differences represent a direct and cumulative selection response of 9% of the mean, of which 6.8% was obtained in the first generation. Heritability of IMF content was moderate to high (0.37) with a probability of 97% of being greater than 0.20. The response to selection estimated using an animal model was 0.033, 0.052 and 0.054 g/100 g muscle in line High and -0.032, -0.046, and -0.051 g/100 g muscle in line Low in the first, second, and third generation, respectively. Results of the present experiment confirmed that IMF content can be improved through selection in rabbits.
