Abstract
AIM To facilitate the routine tasks performed by radiologists in their evaluation of breast radiology reports, by enhancing the communication of relevant results to referring physicians via a natural language processing (NLP)-based system to classify and prioritise Breast Imaging Reporting Data System (BI-RADS). MATERIALS AND METHODS A NLP-based system was developed to classify and prioritise BI-RADS categories from breast ultrasound and mammogram reports, with the potential to streamline and speed up the standard procedures that radiologists must follow to evaluate and categorise breast imaging results. BI-RADS category extraction was divided into two specific tasks: (1) multi-label classification of BI-RADS categories (0-6) and (2) classification of high-priority (BI-RADS 0, 3, 4 and 5) and low priority (BI-RADS 1, 2, and 6) reports according to the previous BI-RADS assessment. RESULTS To develop the NLP tool, three different Bidirectional Encoder Representations from Transformers (BERT)-based models (XLM-RoBERTa, BETO, and Bio-BERT-Spanish) were trained and tested on three distinct corpora (containing only breast ultrasound reports, only mammogram reports, or both), and achieved an accuracy of 74.29-77.5% in detecting BI-RADS categories and 88.52-91.02% in prioritising reports. CONCLUSION The system designed can effectively classify all BI-RADS categories present in a single radiology report. In the clinical setting, such an automated tool can assist radiologists in evaluating breast radiology reports and decision-making tasks and enhance the speed of communicating priority BI-RADS reports to referring physicians.

Abstract
We present a combined experimental and theoretical study of the fragmentation of singly and doubly N-methylated glycine (sarcosine and N,N-dimethyl glycine, respectively) induced by low-energy (keV) O6+ ions. Multicoincidence mass spectrometry techniques and quantum chemistry simulations (ab initio molecular dynamics and density functional theory) allow us to characterise different fragmentation pathways as well as the associated mechanisms. We focus on the fragmentation of doubly ionised species, for which coincidence measurements provide unambiguous information on the origin of the various charged fragments. We have found that single N-methylation leads to a larger variety of fragmentation channels than in no methylation of glycine, while double N-methylation effectively closes many of these fragmentation channels, including some of those appearing in pristine glycine. Importantly, the closure of fragmentation channels in the latter case does not imply a protective effect by the methyl group.

Abstract
BACKGROUND Although the number of nationwide clinical registries in upper gastrointestinal cancer is increasing, few of them perform regular clinical audits. The Spanish EURECCA Esophagogastric Cancer Registry (SEEGCR) was launched in 2013. The aim of this study was to assess the reliability of the data in terms of completeness and accuracy. METHODS Patients who were registered (2014-2017) in the online SEEGCR and underwent esophagectomy or gastrectomy with curative intent were selected for auditing. Independent teams of surgeons visited each center between July 2018 and December 2019 and checked the reliability of data entered into the registry. Completeness was established by comparing the cases reported in the registry with those provided by the Medical Documentation Service of each center. Twenty percent of randomly selected cases per hospital were checked during on-site visits for testing the accuracy of data (27 items per patient file). Correlation between the quality of the data and the hospital volume was also assessed. RESULTS Some 1839 patients from 19 centers were included in the registry. The mean completeness rate in the whole series was 97.8% (range 82.8-100%). For the accuracy, 462 (25.1%) cases were checked. Out of 12,312 items, 10,905 were available for verification, resulting in a perfect agreement of 95% (87.1-98.7%). There were 509 (4.7%) incorrect and 35 (0.3%) missing entries. No correlation between hospital volume and the rate of completeness and accuracy was observed. CONCLUSIONS Our results indicate that the SEEGCR contains reliable data.

Abstract
Abstract
INTRODUCTION
Spleen is frequently damaged in abdominal trauma. Patients with splenic injury with hemodynamic instability, peritonism signs or other surgical injuries need emergent surgery. Hemodynamically stable patients are treated conservatively. Splenic embolization is indicated in injuries with blush, pseudoaneurysms or arteriovenous fistulas. It is unclear its indication in IV and V-grade splenic injuries without contrast extravasation.
Our hypothesis is that IV and V-grade splenic injuries embolization decreases conservative treatment failure.
MATERIAL AND METHODS
Retrospective observational study, including all patients with blunt splenic injuries, prospectively included in our registry of polytraumatic patients (>16 years) since 2006.
RESULTS
One hundred and seventy patients have been included since 2006. In 2006-2013, when splenic injuries with active bleeding, pseudoaneurysms or arteriovenous fistulas were embolized, 94 patients were included. 37,2% required surgery and 62,8% conservative treatment. Splenic embolization was performed in 17% of patients who were treated conservatively. Conservative treatment failure was 16,9%: 10 cases out of those who underwent medical treatment (4 required embolization and 6 needed surgery).
From 2014 to the present, when IV and V-grade injuries were included in the indications for embolization, 76 patients have been included. 38,2% required surgery and 61,8% were treated conservatively (40,4% were embolized and the rest were treated medically). One case (3,6%) of those treated medically and another (5,3%) of those embolized failed. Overall failure of conservative treatment was 4,3%.
CONCLUSION
Embolization of IV and V-grade splenic injuries decreases conservative treatment failure from 16,9% to 4,3%.

Abstract
BACKGROUND To demonstrate whether extensive intraoperative peritoneal lavage (EIPL) could yield better results in overall survival and less recurrence, regardless of peritoneal cytology, compared to standard peritoneal lavage (SPL). METHODS A prospective randomised multicenter study including 94 patients (47 per arm) to detect a 20% difference in 3-year overall survival in patients with locally advanced tumours without peritoneal carcinomatosis. Three samples of peritoneal fluid were obtained (at the beginning, the end of procedure and after the assigned peritoneal lavage). Clinicopathological and surgical data were analysed by group. Postoperative complications, location of recurrence and surgical approach were evaluated. Overall survival was calculated by the Kaplan-Meier method and the uni/multivariate analysis for prognostic factors was carried out using Cox regression analysis. RESULTS A total of 86 patients were analysed (4 excluded per group). No statistical differences were observed in clinicopathological or surgical data between groups, considering both groups well-balanced for analysis. Overall survival at 3 years was 64.3% for SPL vs. 62.3% for EIPL (p 0.421). Only three patients had at least one positive peritoneal cytology (1:2). There were no differences regarding postoperative complications (SPL: 37.2% vs. EIPL: 32.5%, p 0.65) or between location of recurrence and number of recurrences. The number of recurrences did not differ between surgical approaches, but locoregional and peritoneal recurrences were fewer with the laparoscopic approach (p 0.048). CONCLUSIONS The regular use of extensive peritoneal lavage in patients with locally advanced gastric cancer, regardless of peritoneal cytology, has not been effective as prophylaxis of peritoneal recurrence or better survival.

Abstract
The use of artificial intelligence (AI) algorithms in the field of radiology is becoming more common. Several studies have demonstrated the potential utility of machine learning (ML) and deep learning (DL) techniques as aids for radiologists to solve specific radiological challenges. The decision-making process, the establishment of specific clinical or radiological targets, the profile of the different professionals involved in the development of AI solutions, and the relation with partnerships and stakeholders are only some of the main issues that have to be faced and solved prior to starting the development of radiological AI solutions. Among all the players in this multidisciplinary team, the communication between radiologists and data scientists is essential for a successful collaborative work. There are specific skills that are inherent to radiological and medical training that are critical for identifying anatomical or clinical targets as well as for segmenting or labelling lesions. These skills would then have to be transferred, explained, and taught to the data science experts to facilitate their comprehension and integration into ML or DL algorithms. On the other hand, there is a wide range of complex software packages, deep neural-network architectures, and data transfer processes for which radiologists need the expertise of software engineers and data scientists in order to select the optimal manner to analyse and post-process this amount of data. This paper offers a summary of the top five challenges faced by radiologists and data scientists including tips and tricks to build a successful AI team.

Abstract
BACKGROUND AND PURPOSE Spain has been one of the countries more heavily stricken by SARS-CoV-2, which has had huge implications for stroke care. The aim was to analyse the impact of the COVID-19 epidemic outbreak on reperfusion therapies for acute ischaemic stroke in the northwest of Spain. METHODS This was a Spanish multicentre retrospective observational study based on data from tertiary hospitals of the NORDICTUS network. All patients receiving reperfusion therapy for ischaemic stroke between 30 December 2019 and 3 May 2020 were recorded, and their baseline, clinical and radiological characteristics, extra- and intra-hospital times of action, Code Stroke activation pathway, COVID-19 status, reperfusion rate, and short-term outcome before and after the setting of the emergency state were analysed. RESULTS A total of 796 patients received reperfusion therapies for ischaemic stroke. There was a decrease in the number of patients treated per week (46.5 patients per week vs. 39.0 patients per week, P = 0.043) and a delay in out-of-hospital (95.0 vs. 110.0 min, P = 0.001) and door-to-needle times (51.0 vs. 55.0, P = 0.038). Patients receiving endovascular therapy obtained less successful reperfusion rates (92.9% vs. 86.6%, P = 0.016). COVID-19 patients had more in-hospital mortality. CONCLUSION A decrease in the number of patients benefiting from reperfusion therapies was found, with a delay in out-of-hospital and door-to-needle times and worse reperfusion rates in northwest Spain. COVID-19 patients had more in-hospital mortality.

Abstract
We studied the influences of the thickness of the porous silicon layer and the conductivity type on the porous silicon sensors response when exposed to ethanol vapor. The response was determined at room temperature (27 ∘C) in darkness using a horizontal aluminum electrode pattern. The results indicated that the intensity of the response can be directly or inversely proportional to the thickness of the porous layer depending on the conductivity type of the semiconductor material. The response of the porous sensors was similar to the metal oxide sensors. The results can be used to appropriately select the conductivity of semiconductor materials and the thickness of the porous layer for the target gas.

Abstract
Breast cancer spreading to different organs have been related to different molecules and mechanisms, but cutaneous metastasis remains unexplored. Increasing evidence showed that MUC1 and some of its carbohydrate associated antigens may be implicated in breast cancer metastasis. In this study we analyzed these tumor markers in order to identify breast cancer cutaneous metastatic profiles. A cohort of 26 primary tumors from breast cancer patients with cutaneous metastases were included; also, cutaneous and lymphatic node metastatic samples and primary tumors from breast cancer patients without metastases were analysed. Immunohistochemical (IHC) studies demonstrated that both underglycosylated MUC1 (uMUC1) and sialyl Lewis x (sLex) to be positively associated with cutaneous metastatic primary tumors (p < 0.05). Notably, a high percentage of tumors with cutaneous metastases were characterized as triple negative and Her2+ tumors (37.5 % and 29 %, respectively). Some discordant results were found between primary tumors and their matched cutaneous metastases. To determine if MUC1 variants may be carriers of carbohydrate antigens, subcellular fractions from a cutaneous metastatic lesion were obtained, immunoprecipitated and analyzed by Western blot. We found that the isolated uMUC1 with a molecular weight of>200 kDa was also the site for binding of anti-sLex MAb; in coincidence, a high correlation of positive IHC expression of both markers was observed. Our findings confirm that breast cancer cutaneous metastases were associated to highly malignant primary tumors and sustain the hypothesis that u-MUC1 and sLe x may drive breast cancer cutaneous metastases.

Abstract
BACKGROUND AND PURPOSE Perioperative chemotherapy (periCTX) based on the "MAGIC" scheme has become a standard treatment in Europe for locally advanced oesophagogastric cancer. We assessed implementation and long-term oncological outcomes of MAGIC periCTX for locally advanced gastric cancer. METHODS Population-based cohort study of all patients with locally advanced gastric cancer undergoing surgical resection with curative intent in Catalonia and Navarra (the first two autonomous communities included in the EURECCA Upper GI Spanish Working Group) between January 2011 and December 2013. The main variable was the percentage of patients treated with MAGIC periCTX. Kaplan-Meier analysis and Cox proportional hazards model were used to assess the survival benefit of periCTX. RESULTS Among 814 patients, 217 (26.6%) received periCTX (especially patients more likely to receive it: aged < 70 years, with proximal tumors, low anesthetic risk, and cT3-4/cN+ clinical stage). 35% did not complete perioperative chemotherapy, with no relationship with age. PeriCTX showed no effect on postoperative morbimortality. Histological tumor regression was more often absent or poor (38.2%) than total or almost total (27.8%), although clinico-pathological lymph-node downstaging was higher than expected by staging inaccuracy (38.7% vs. 24.2%). PeriCTX was associated with a better survival only in cT3-4 and cN+ patients, showing less prognostic relevance than optimal oncological surgery with D2 lymphadenectomy. CONCLUSIONS Only 26.6% of locally advanced resectable gastric cancer patients received PeriCTX. Pathological response was poor, although some degree of nodal downstaging was observed. Survival benefit of periCTX was limited to cT3-4 and cN+ patients, being less relevant than D2 lymphadenectomy.

Abstract
CONTEXT High-mass stars and star clusters commonly form within hub-filament systems. Monoceros R2 (hereafter Mon R2), at a distance of 830 pc, harbors one of the closest such systems, making it an excellent target for case studies. AIMS We investigate the morphology, stability and dynamical properties of the Mon R2 hub-filament system. METHODS We employ observations of the 13CO and C18O 1→0 and 2→1 lines obtained with the IRAM-30m telescope. We also use H2 column density maps derived from Herschel dust emission observations. RESULTS We identified the filamentary network in Mon R2 with the DisPerSE algorithm and characterized the individual filaments as either main (converging into the hub) or secondary (converging to a main filament) filaments. The main filaments have line masses of 30-100 M ⊙ pc-1 and show signs of fragmentation, while the secondary filaments have line masses of 12-60 M ⊙ pc-1 and show fragmentation only sporadically. In the context of Ostriker's hydrostatic filament model, the main filaments are thermally supercritical. If non-thermal motions are included, most of them are trans-critical. Most of the secondary filaments are roughly transcritical regardless of whether non-thermal motions are included or not. From the morphology and kinematics of the main filaments, we estimate a mass accretion rate of 10-4-10-3 M ⊙ yr-1 into the central hub. The secondary filaments accrete into the main filaments with a rate of 0.1-0.4×10-4 M ⊙ yr-1. The main filaments extend into the central hub. Their velocity gradients increase towards the hub, suggesting acceleration of the gas.We estimate that with the observed infall velocity, the mass-doubling time of the hub is ~ 2:5 Myr, ten times larger than the free-fall time, suggesting a dynamically old region. These timescales are comparable with the chemical age of the Hii region. Inside the hub, the main filaments show a ring- or a spiral-like morphology that exhibits rotation and infall motions. One possible explanation for the morphology is that gas is falling into the central cluster following a spiral-like pattern.

Abstract
Consumer concern on the quality of products and animal welfare has greatly increased during the past decades. Dietary synthetic antibiotic products used as growth promoters have been restricted or banned in many countries. Edible plants, essential oils, or their main components were suggested as natural feed supplements to improve growth, products' quality, and welfare-related parameters. Thymol (THY), a main component of oregano essential oil, has been proved as an effective antimicrobial and antioxidant compound. Tocopherol (TOC) evidenced antioxidant activity with potential as a growth promoter and a synergic antioxidant activity between TOC and ascorbyl palmitate (AP) has also been reported. Herein, we evaluated whether broiler diet supplementation with THY, and THY with a formulation mix containing TOC and AP (1:0.5:0.5, respectively) have potential as growth enhancers under commercial conditions. Potential protective effects against foot pad dermatitis and hock burns were also evaluated. Newly hatched male broiler chicks with similar body weight (BW) were randomly assigned to 1 of 7 groups (4 replicates each) as follows: Basal (no feed supplements added), Promotor (Basal + 6.26 μmol flavomycin/kg feed), BHT (Basal + 1.33 mmol of buthylated hidroxytoluene (BHT)/kg feed), Prom-BHT (Basal + 6.26 μmol flavomycin/kg feed + 1.33 mmol of BHT/kg feed), TOC-AP (Basal + 0.67 mmoles of TOC + 0.67 mmoles of AP/kg feed), THY (Basal + 1.33 mmoles of THY/kg feed), and THY-TOC-AP (Basal + 0.67 mmoles of THY + 0.67 mmoles of a mix 1:1 of TOC-AP). Along 7 wk, BW, feed intake, and feed conversion ratio were evaluated. Skin injuries were assessed at 35 d of age. At the end of the study (42 d), compared to Basal group, similarly enhanced final BW were observed in all groups but TOC-AP. No main differences between groups were detected in feed intake, feed conversion ratio, or skin injuries. Findings suggest that THY itself or in combination with TOC-AP may have value as a natural growth enhancer alternative for broilers.

Abstract
In addition to the classical morphological evaluation of pancreatic disease, the constant technological advances in imaging techniques based fundamentally on computed tomography and magnetic resonance imaging have enabled the quantitative functional and molecular evaluation of this organ. In many cases, this imaging-based information results in substantial changes to patient management and can be a fundamental tool for the development of biomarkers. The aim of this article is to review the role of emerging functional and molecular techniques based on computed tomography and magnetic resonance imaging in the evaluation of pancreatic disease.

Abstract
Antioxidant are regularly included in poultry feed as protection from deterioration during storage. Recently the interest for the use of natural phytochemicals in animal diets has been increased. Thymol (THY) has been proven to be an effective antioxidant for extending broiler meat quality during storage with similar action to the widely used butylated hydroxytoluene (BHT). This study evaluates whether THY can also have a protective effect on the feed mash by assessing its antioxidant potential and related changes in fatty acid (FA) balance. Feed mash was assigned to 1 of 4 treatments, control (CON, no additive), vehicle (VEH, ethanol 96%), BHT (400 mg BHT /kg feed) and THY (400 mg THY /kg feed). Three replicates of each treatment were taken after 0, 30, and 60 d of storage at room temperature (23 ± 3°C) and relative humidity (40 ± 5%). Peroxide value (PV), titratable acidity (TA) and FA relative composition were determined. As expected, there were no treatment effects on those variables at 0 d of storage. However, higher PV values were detected in the CON and VEH groups after 30 and 60 d of storage in comparison to the THY and BHT treated samples (CON = VEH > THY = BHT). While a slight increase was also observed in TA through storage time, no particular treatment effects were detected. Relative FA composition changed with storage time only in the CON and VEH group which had a decrease in polyunsaturated fatty acids and an increase in saturated FA. No changes were detected in the Thy and BHT treated feeds. The results suggest a similar THY and BHT protective effect on feed mash lipid oxidation. Thus, THY could be considered as a useful natural alternative to help sustain quality of poultry feed.

Abstract
INTRODUCTION This study shows the results obtained from evaluating the main psychosocial stressors perceived in the process of social reintegration and their relation to a remaining sentence time in prison. MATERIAL AND METHODS A questionnaire based on an ad hoc design was administered, using a Likert scale, with a total of 383 inmates serving sentences in southeast Spain. RESULTS Findings show that inmates with a remaining sentence period of more than one year, like those who had served more than a year of their sentence, showed greater concern about possible economic difficulties. CONCLUSIONS The psychosocial stressors studied might provide relevant information to facilitate the process of social reintegration after the completion of a prison sentence.

Abstract
The behaviour of different coagulant enzymes during the coagulation of goat's milk was studied by diffuse reflectance. During the first 5 min a decrease was observed in the diffuse reflectance profile which correlated with the recorded decrease in viscosity measurements; this decrease was followed by a continuous increase in the reflectance value. The milk clotting time for all the enzymes studied can be calculated from a plot of the first derivative of the diffuse reflectance value vs time by assuming the maximum value of the first derivative. There were no significant differences ( p ≤ 0.05) between the milk clotting time determined by diffuse reflectance and the value obtained using the Berridge method.

Abstract
The objective of this study was to characterize cardiac sympathetic denervation in Parkinson's disease (PD) patients without neurogenic orthostatic hypotension (NOH), both in terms of hemodynamics and in its relation with vascular denervation. We studied 20 PD patients without NOH. We analyzed the heart rate and blood pressure variability during various physical maneuvers. The following parameters were calculated: expiratory-inspiratory ratio, stroke volume, cardiac output, cardiac index, left ventricular ejection time, left ventricular work index, thoracic fluid content, total peripheral resistance and baroreflex sensitivity (BRS). We also measured direct and spectral derivatives of cardiac (cardiovagal) parasympathetic function. Myocardial I-123 metaiodobenzylguanidine (MIBG) scintigraphy was performed and early and late heart/mediastinum uptake ratios were analyzed. We observed that the late heart/mediastinum uptake ratio was 1.33±0.21. This parameter was correlated with years since diagnosis (correlation coefficient:-0.485; P=0.05), Unified Parkinson's Disease Rating Scale (UPDRS) III score (cc:-0.564; P=0.02) and pressure recovery time in the Valsalva maneuver (cc: 0.61; P<0.001). At rest, it was correlated with BRS (cc:0.75; P=0.003) and low-frequency diastolic blood pressure (LFDBP; cc: 0.58;P=0.017). We found no correlations with any of the cardiography impedance variables. In linear regression models, the variable that best correlated with MIBG results was LFDBP. Our results support that in absence of NOH the degree of denervation of the heart does not produce any effect on its inotropic function. Moreover, BRS and LFDBP can be used as an indirect measure of cardiac sympathetic denervation at rest.

Abstract
Many problems in poultry production are caused by a combination of interrelated factors such as management, stress, nutrition, and exposure to pathogens. Saprophagous flies that develop in poultry manure are a potential route of pathogen transmission. Besides being a nuisance, defecation and regurgitation of flies soil equipment and structures and can reduce light levels of lighting fixtures. These effects clearly affect management and may contribute to reductions in poultry egg production, health, and welfare. Many essential oils or their main components have bioactive effects such as natural repellents and insecticides, antioxidants, anticholesterolemics, and antimicrobials. This study evaluated if supplementing quail feed with thymol or isoeugenol as functional food could alter the production of flies from manure. Dropping samples deposited by quail fed with a supplementation of 2,000 mg of thymol or isoeugenol per kg of feed or no supplement (control) were collected. Each sample was incubated inside an emergence cage that was inspected daily to collect emerging adult flies. Fewer flies emerged from droppings of quail fed a thymol-supplemented diet (P = 0.01) and there was a tendency to a lower emergence from droppings of isoeugenol-fed quail (P = 0.09). The number of positive containers for Musca domestica was smaller from quail droppings of thymol- (P = 0.02) or isoeugenol- (P = 0.01) supplemented feed than from the control counterparts, suggesting an oviposition repellent effect. Supplementing quail feed with thymol or isoeugenol has an overall moderate effect against flies, reducing M. domestica emergence.

Abstract
Dissemination of knowledge in genetics to be applied in medicine has created a growing need for capacity building in health care workers. The CAPABILITY ARGENTINA outreach project protocol was designed as a model to introduce genetics in areas without genetic services. Our aim was for genetic health care to become part of primary care in an Argentine province lacking genetic services. The program was innovative as professionals from the referral center (Garrahan Hospital S.A.M.I.C.) traveled to remote areas to train professionals through problem-based education. A logical framework was designed for a local needs assessment. Teaching materials (Powerpoint presentations, printed syllabus, and CD) and a web page were developed. A demonstration project was carried out in the Province of Chaco, Argentina. A total of 485 health workers were trained. The number of consultations increased significantly in participating areas comparing before and after the training period. To support this increase, a complementary project was set up from a public hospital sponsored from within Argentina to build a cytogenetic laboratory in the capital of the Province of Chaco. The model was improved for reproduction in other areas in Argentina. CAPABILITY ARGENTINA is a capacity building model for training of primary care professionals in genetics that may be applied to other medical specialties. The outcomes of the programme have a direct impact on clinical practice.

Abstract
BACKGROUND This study aimed to analyze nerve trunk anatomy in the infraclavicular fossa and to correlate these data with the most common anthropometric parameters. METHODS A Mylab 30 Gold (Esaote) and the linear transducer LA523 (7.5 MHz frequency) were used. The probe was oriented according to a parasagittal plane, parallel to the lateral chest wall and immediately medial to the coracoid process underneath the clavicle. Measurements included the distance between the artery and the cutaneous surface (mm) and the apical corner of the ultrasound image (mm), the number of identified nervous cords and their position related to the axillary artery, and the position and number of axillary veins. Sex, age, height, weight, body mass index (BMI), biceps girth, and breast size were recorded. Statistical analysis included calculation of linear Pearson correlation coefficient and Student's t test. RESULTS Two hundred and two consecutive patients were enrolled. The position of the three cords was highly variable around the artery. In a small but significant percentage of patients (8.9%), the medial and the lateral cords were located together at the top of the artery. The visibility of the trunks and the distance between the upper part of the artery and the apical corner of the ultrasound image correlated with anthropometric characteristics. The vein position with respect to the artery and nerves was markedly variable. CONCLUSION Sono-anatomic study of the infraclavicular region adds important data that is useful when conducting nerve blocks to improve safety and likelihood of success.

Abstract
The aim of our study was to analyse several serum biochemical markers in order to evaluate the discriminant capacity of trace elements individually and jointly in drowning (seawater drowning and freshwater drowning) and their correlation with age, sex, postmortem interval, time in water and concentrations of the trace elements in the drowning medium. Sixty-seven cases of drowning (53 seawater drownings (SWD); 14 freshwater drownings (FWD) and 73 control cases (other asphyxias, n=44, and other causes of death, n=29) were selected according to the scene, cause and circumstances of death, together with autopsy findings. Serum strontium (Sr), magnesium (Mg), sodium (Na), chloride (Cl), calcium (Ca), iron (Fe), urea, creatinine (Cr) and cardiac Troponine T (cTn-T) were measured in the left ventricle (Lv), right ventricle (Rv) and peripheral blood. Lv-Rv differences for each marker and Sr, Mg, Na, Cl, Ca and Fe concentrations in the drowning medium were determinated. Mean concentrations of Sr, Cl and Mg in both ventricles and peripheral serum and Lv-Rv differences and Ca Lv and Na Rv were significantly higher in cases of drowning than for other causes of death. In SWD, Sr, Mg, Ca, Na and Cl were significantly higher in Lv than in Rv as a result of aspirating water. In contrast, haemodilution is evident from the significantly higher levels of Fe and urea in Rv than in Lv in cases of SWD, and from the higher Mg and Cr levels in Rv in FWD. In the case of SWD, serum levels of Sr are confirmed as the best parameter for diagnosis, although other trace elements may also be useful, such as the serum concentrations of Mg and Cl. In the case of FWD, the joint determination of Sr and other biochemical markers, especially Fe, may increase correct diagnosis.

Abstract
Vitreous humour is routinely sampled in Forensic Medicine as several post-mortem analyses can be performed. However, it is not used for DNA analyses probably due to its scarce cellularity. In these samples, in which the study of nuclear DNA is difficult, the analysis of mtDNA is an alternative approach. The aim of this study was to investigate the utility of vitreous humour for forensic identification purposes. Samples were collected during vitrectomy from retinopathy patients, in collection bags with saline solution. Blood samples were also obtained in order to contrast results. Before DNA organic extraction, several centrifugation steps were needed to concentrate the vitreous humour samples. Unlike blood, direct amplification of 400-bp fragments of the hipervariable regions I and II (HVI and HVII) was not successful, possibly due to damage to the DNA strand caused by the surgery conditions (UV radiation, oxidative stress). Therefore, amplification of two overlapping fragments for each control region was performed in vitreous humour. In order to eliminate undesired products, all samples were purified by an enzymatic method. Thereafter, mtDNA fragments were sequenced using dye terminators in a MegaBACE 500 capillary sequencer. Sequences of HVI and HVII of approximately 400 bp were obtained from all samples. The sequences obtained from each patient matched almost perfectly those from blood. In summary, herein we describe for the first time a methodology suitable for the mtDNA analysis of vitreous humour samples.

Abstract
The histopathological alterations that permit the diagnosis of death by asphyxia are very unspecific, although pulmonary alterations are of great importance in this respect. The postmortem diagnosis of drowning, particularly, continues to be one of the most difficult in forensic pathology. The aim of this study is to jointly evaluate microscopic findings and immunohistochemical surfactant protein A (SP-A) expression in the upper and lower lobes of lungs in different causes of death, and their possible application to the diagnosis of drowning. We studied 120 cadavers from subjects with a mean age of 48.73 years (SD 19.45; range 2-86 years), and with a mean post-mortem interval of 30 hours (SD 39.59; range 3-216 hours). According to the scene, cause and circumstances of death, and autopsy findings, cases were classified into groups as follows: (a) drowning (n=47); (b) other asphyxia (n=44) and (c) other causes (n=29). In the upper and lower lobes of lungs, histological studies of H&E staining and immunohistochemical surfactant protein A expression were made. The presence and severity of congestion, haemorrhage and oedema, together with immunohistochemical SP-A expression, may have a diagnostic value in differentiating asphyxia and drowning from other causes of death, and drowning from other types of asphyxia. Our findings suggest that both lobes should be investigated to establish the diagnosis, although the findings in the upper lobe might be the most important for differentiating the exact cause of death.

Abstract
Elder abuse is recognized internationally as a growing problem. Recent years have seen an increase in the number of authors recommending that the MDs systematically question old people concerning possible abuse. The aim of our study was to ascertain the extent of suspicion of elder abuse and the different types of abuse. We design a cross-sectional survey including 460 patients > or = 65 years at different health centers (South East Spain). A face-to-face interview and a physical examination was carried out. Extent of suspected abuse was 44.6%. Female sex, > or = 75 years, widowhood, living alone or with children, accommodation in house of relatives and income < or = 300 euros/month were the associated sociodemographic variables. The risk factors associated are recent worsening of health, living with a mentally ill person, excessive consumption of alcohol or illegal drugs, arguing frequently with relatives or the dependence on someone to carry out a daily activity. The signs in the physical examination associated are dehydration/malnutrition, pressure ulcers and poor body and/or mouth hygiene. There is a high extent of suspicion of elder abuse and the keyword in this respect is prevention.

Abstract
Suicidal behavior is a problem with important social repercussions. Some groups of the population show a higher risk of suicide; for example, depression, alcoholism, psychosis or drug abuse frequently precedes suicidal behavior. However, the relationship between metabolic alterations in the brain and premorbid clinical symptoms of suicide remains uncertain. The serotonergic and noradrenergic systems have frequently been, implicated in suicidal behavior and the amount of serotonin in the brain and CSF of suicide victims has been found to be low compared with normal subjects. However, there are contradictory results regarding the role of noradrenergic neurons in the mediation of suicide attempts, possibly reflecting the heterogeneity of conditions that lead to a common outcome. In the present work we focus on the subgroup of suicide victims that share a common diagnosis of major depression. Based on post-mortem studies analyzing mRNA expression by in situ hybridization, serotonergic neurons from the dorsal raphe nucleus (DRN) from depressive suicide victims are seen to over-express cytochrome oxidase mRNA. However, no corresponding changes were found in the expression of tyrosine hydroxylase (TH) mRNA in the noradrenergic neurons of the Locus Coeruleus (LC). These results suggest that, despite of the low levels of serotonin described in suicide victims, the activity of DRN neurons could increase in the suicidally depressed, probably due to the over activation of serotonin re-uptake. No alteration was found in noradrenergic neurons, suggesting that they play no crucial role in the suicidal behavior of depressive patients.

Abstract
Trace element determination can be applied in forensic medicine to diagnose the cause of death. Drowning is the second leading cause of death from unintentional injury. Despite the many diagnostic methods used, the post-mortem diagnosis of drowning continues to be one of the most difficult in forensic pathology. Strontium is a highly sensitive marker of water aspiration in a liquid medium rich in this metal. The aims of this study were to confirm the diagnostic value of strontium in cases of drowning compared with other causes of death, to analyse factors that could affect its concentration and to ascertain the sensitivity and specificity of strontium in right and left ventricles and peripheral serum for the post-mortem diagnosis of drowning. We studied 120 cadavers selected from medico-legal autopsies with different causes of death. Strontium (Sr) levels were measured in the serum (left and right ventricles and peripheral vein) of all cadavers and, in the case of drowning, in the water medium itself, by using Zeeman AAS. Our results confirm the usefulness of blood Sr levels for diagnosing seawater and freshwater drowning, although great care should be exercised in the latter case.

Abstract
BACKGROUND Sharing information with relatives of elderly patients in primary care and in hospital has to fit into the complex set of obligations, justifications and pressures concerning the provision of information, and the results of some studies point to the need for further empirical studies exploring issues of patient autonomy, privacy and informed consent in the day-to-day care of older people. OBJECTIVES To know the frequency with which "capable" patients over 65 years of age receive information when admitted to hospital, the information offered to the families concerned, the person who gives consent for medical intervention, and the degree of satisfaction with the information received and the healthcare provided. METHOD A descriptive questionnaire given to 200 patients and 200 relatives during the patients' stay in hospital. RESULTS Only 5% of patients confirmed that they had been asked whether information could be given to their relatives. A significantly higher proportion of relatives received information on the successive stages of the care offered than did patients themselves. As the age of the patients increased, so the number who were given information, understood the information and were asked for their consent for complementary tests decreased. The degree of satisfaction with the information offered was high for both patients and relatives (86.5% and 84%, respectively), despite the irregularities observed. CONCLUSIONS The capacity of elderly patients to participate in the decision-making process is frequently doubted simply because they have reached a certain age and it is thought that relatives should act as their representatives. In Spain, the opinion of the family and doctors appears to play a larger role in making decisions than does the concept of patient autonomy.

Abstract
This paper represents a reflection on the limits and objectives of the information pharmacists should offer in pharmacies. The obligation of a pharmacist to follow the patient's therapeutic progress makes it necessary to integrate this figure into an ethical-legal framework and to define the objective of the health-related information offered, taking into account the patient's welfare and constitutional rights.

Abstract
We studied the impact of various motor and nonmotor symptoms upon quality of life in patients with Parkinson's disease (PD). The study comprised 110 patients with PD (age: 68.6 years, course of the disease: 7.6 years). The Unified Parkinson Disease Rating Scale (UPDRS; I-IV) and Parkinson's Disease Questionnaire (PDQ-39) were recorded. We recorded the correlations between years of disease and UPDRS IV, as well as PDQ-39 and UPDRS I, II, III and IV. Introduction of all variables into a linear regression model showed that 3 variables accounted for 51% of the variance in PDQ-39. Mental condition, gait disorders and complications of dopaminergic drugs are the variables that most affect the quality of life of patients with PD.
