Abstract
Klebsiella spp. is an important pathogen in humans and animals and due to the indiscriminate use of antibiotics, its prevalence and antibiotic resistance has increased in companion animals. The main goal of this study was to investigate the prevalence and antibiotic resistance of Klebsiella spp. isolated from clinically ill cats and dogs admitted in veterinary clinics in the North of Portugal. A total of 255 clinical specimens were collected and, after isolation, the identification of Klebsiella strains was performed using the BBL Crystal™ identification system and confirmed by PCR-based sequencing with specific primers. Antibiotic resistance profile was determined through the disc diffusion method. Beta-lactam resistance genes were screened through a multiplex PCR assay. Fifty Klebsiella strains were isolated and, 39 were identified as Klebsiella pneumoniae and 11 as Klebsiella oxytoca. Thirty-one were recovered from dogs and 19 from cats. The Klebsiella isolates were recovered mainly from skin wounds, respiratory tract, and from urine. Fifty percent of K. oxytoca and K. pneumoniae isolates revealed to be Multidrug Resistant (MDR) strains, with most of them positive for the presence of blaTEM-like and blaSHV genes. This data shows that MDR Klebsiella are highly disseminated in companion animals and that extended-spectrum beta-lactamases can be easily found among these isolates. This highlights the potential role of dogs and cats as a reservoir of resistant Klebsiella spp. that have the potential to be transmitted to humans.

Abstract
Abstract
Introduction
Cryptogenic stroke (CS) represents one-third of ischemic strokes. Atrial fibrillation (AF) can be detected in up to 30% of CS. Therefore, there is a clinical need for predicting AF to guide the optimal secondary prevention strategy. The evidence about the role of advanced echocardiography, including left atrial 3D index volume and left atrial strain (LAS) techniques, to predict underlying AF in this setting is lacking.
Methods
From April 2019 to November 2021 seventy-eight consecutive patients with ischemic stroke or transient ischemic attack with ABCD2 scale ≥4 of unknown etiology were prospectively recruited. Echocardiography was performed during admission. All patients underwent 15 days wearable Holter monitoring. The primary outcome measure was AF detection during follow-up.
Results
Twenty -two patients (28%) developed AF. Patients in the AF group were older (81±6.3 vs 76.5±7.8 years; p=0.012). Left atrial (LA) diastolic indexed volume was higher in AF group (37.2±12.8 vs 29.7±11 ml/m2 p=0.01). 3D LA indexed volume were also higher in patients with AF (41.4±14 vs 32.2±10 ml/m2 p=0.009). LAS reservoir, LAS conduct and LAS contraction (LASct) were significantly lower in patients with AF (19±5.6 vs 32±10.3%; 9±4.5 vs 15±7.6; 10±5.3 vs 17±6.4, respectively, all p<0.001). On multivariate analysis LASct <13.5% and LA 3D indexed volume >44.5 ml/m2 were independent predictors of AF (OR 10.9 [95% CI 1.09–108.2], p=0.042) (Table 1, Figure 1)
Conclusion
LASct <13.5% and LA 3D indexed volume >44.5 ml/m2 are independent predictors of underlying AF in patients with CS. Our results demonstrate the usefulness of advanced echocardiography in this challenging clinical setting.

Abstract
Background: Systemic cancer therapy has traditionally been administered using an intravenous (IV) route, implying patients’ frequent visits to hospitals to access to their therapy. If we consider the actual pipeline in oncology, oral chemotherapy will be the main component of cancer treatment in the next few years. This shift in the administration route requires different care models in order to guarantee treatment efficacy and safety. Objective: To analyze time trends in oral chemotherapy consumption in Portugal. Method: Oral chemotherapy consumption over a 13-year period (2008–2020) was analyzed, considering dispensed units by the administration route with respective costs, resorting to the drug regulatory agency (INFARMED I.P.) database. Oral consumption patterns were further explored using common daily doses (CDD) for three conditions, including chronic myeloid leukemia (CML), non-small-cell lung cancer (NSCLC), and breast cancer (BC), to adjust for the effect of varying doses. Data were analyzed descriptively resorting to Microsoft Office Excel 2010. Results: Overall chemotherapy consumption increased +Δ54.7%, with the highest contribution in units observed in oral forms (+Δ58.8%). The total expenditure increased +Δ96.5%, and despite the increase in oral forms (+Δ221.6%), intravenous forms continued to be the major cost driver, with an important contribution from immunotherapy. Much of the increase was led by the approval of 40 new IV and 48 new oral cancer medications with higher costs introduced in the market. Using CDD as an alternative metric to units had varying impacts by indication. The observed increases seemed to focus on specific cancer sites with varying effect; in CML, there was a 2.39-fold increase, compared to 4.41 for NSCLC and 1.86 for BC. However, for BC, two distinct sub-patterns were observed for hormone therapy (increasing 1.83) and for the novel tyrosine kinase inhibitors (increasing 40.8). Conclusion: The growing use of oral chemotherapy is obvious and calls for investments in supporting patients in managing medication adherence and adverse events. The shifts in the healthcare system are complex and need to be prioritized. Our data suggest that priority could be attributed to cancer sites driving innovation, namely, advanced breast cancer.

Abstract
Introduction PTSD is a chronic, debilitating condition with limited treatment efficacy. Accessing traumatic memories often leads to overwhelming distress, impacting treatment process. Current approved pharmacological treatments have exhibited small to moderate effects when compared with placebo. Evidence suggests 3,4,-methylene-dioxymethamphetamine(MDMA)-assisted psychotherapy as a viable option for refractory PTSD. Objectives Comprehensive review of early clinical research, proposed mechanisms, safety and emerging therapeutic models. Methods Eligible studies will be identified through strategic search of MEDLINE. Results Pre-clinical and imaging studies suggest memory reconsolidation and fear extinction as candidate psychological and neurological mechanisms, involving MDMA’s combined effects of increasing serotonergic activity, as well the release of oxytocin and brain-derived neurotrophic factor in key memory and emotional circuits. Resulting reduction in amygdala and insula activation and increasing connectivity between the amygdala and hippocampus may create a “tolerance window” of neuroplasticity for emotional engagement and reprocessing of traumatic memories during psychotherapy. Early clinical trials report impressive and durable reduction in PTSD symptoms, with a safety profile comparable to that of SSRIs. A recently completed randomized, double-blind, placebo-controlled phase 3 trial reported full remission of PTSD symptoms in 67% of patients at 2 months, with no increase in suicidality, cardiovascular events or abuse behavior. Emerging treatment models underline the importance of unmedicated therapeutic sessions for preparation for the experience and subsequent integration as essential for full benefit and safety of the clinical context. Conclusions The psychological impact associated with the COVID-19 pandemic is an reminder of the emotional and economic burden associated with PTSD. MDMA-assisted therapy may be a breakthrough approach meriting further multidisciplinary investment and clinical research. Disclosure No significant relationships.

Abstract
Background The existing digital healthcare solutions demand a service development approach that assesses needs, experience, and outcomes, to develop high-value digital healthcare services. The objective of this study was to develop a digital transformation of the patients’ follow-up service after cardiac surgery, based on a remote patient monitoring service that would respond to the real context challenges. Methods The study followed the Design Science Research methodology framework and incorporated concepts from the Lean startup method to start designing a minimal viable product (MVP) from the available resources. The service was implemented in a pilot study with 29 patients in 4 iterative develop-test-learn cycles, with the engagement of developers, researchers, clinical teams, and patients. Results Patients reported outcomes daily for 30 days after surgery through Internet-of-Things (IoT) devices and a mobile app. The service’s evaluation considered experience, feasibility, and effectiveness. It generated high satisfaction and high adherence among users, fewer readmissions, with an average of 7 ± 4.5 clinical actions per patient, primarily due to abnormal systolic blood pressure or wound-related issues. Conclusions We propose a 6-step methodology to design and validate a high-value digital health care service based on collaborative learning, real-time development, iterative testing, and value assessment.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive diaphragm weakness and deteriorating lung function. Bulbar involvement and cough weakness contribute to respiratory morbidity and mortality. ALS-related respiratory failure significantly affects quality of life and is the leading cause of death. Non-invasive ventilation (NIV), which is the main recognized treatment for alleviating the symptoms of respiratory failure, prolongs survival and improves quality of life. However, the optimal timing for the initiation of NIV is still a matter of debate. NIV is a complex intervention. Multiple factors influence the efficacy of NIV and patient adherence. The aim of this work was to develop practical evidence-based advices to standardize the respiratory care of ALS patients in French tertiary care centres. METHODS For each proposal, a French expert panel systematically searched an indexed bibliography and prepared a written literature review that was then shared and discussed. A combined draft was prepared by the chairman for further discussion. All of the proposals were unanimously approved by the expert panel. RESULTS The French expert panel updated the criteria for initiating NIV in ALS patients. The most recent criteria were established in 2005. Practical advice for NIV initiation were included and the value of each tool available for NIV monitoring was reviewed. A strategy to optimize NIV parameters was suggested. Revisions were also suggested for the use of mechanically assisted cough devices in ALS patients. CONCLUSION Our French expert panel proposes an evidence-based review to update the respiratory care recommendations for ALS patients in daily practice.

Introduction
CHA2DS2-VASc Score is widely used to predict thromboembolic risk in patients with Atrial Fibrillation (AF). However the role of CHA2DS2-VASC score for predicting AF in patients with cryptogenic stroke (CS) remains unknown.
Methods
Sixty-three consecutive patients with ischemic stroke or transient ischemic attack with ABCD2 scale≥4 of unknown etiology, were prospectively recruited. They were classified according to
CHA2DS2-VASc Score: group 1 (score ≤ 5), and group 2 (score >5). The primary outcome measure was the occurrence of AF during clinical follow-up.
Results
Twenty-six (41%) patients had a CHA2DS2VASC score > 5 (group 2). Patients in this group were older (81 ± 5.5 vs 75 ± 8 years; p < 0.001) and more frequently female (73% vs 43% p = 0.019). Patients in group 2 present more often hypertension (84% vs 43% p = 0.001), diabetes (38% vs 11%, p = 0.009) , dyslipidemia 77% vs 49%, p = 0.024), and a prior history of coronary artery disease (27% vs 5%, p = 0.026). Notably, patients with higher CHA2DS2VASC showed worse left atrial ejection fraction (41.7 ± 13.1 vs 52.2 ± 15%, p = 0.009) and worse left atrial strain reservoir (21.5 ± 7.1 vs 33.8 ± 11%, p < 0.001), conduct (9.5 ± 4.8 vs 16.6 ± 8.4%;p < 0.001) and contraction (12 ± 4.6 vs 17.2 ± 7.3, p = 0.002). During follow-up AF was detected more often in group 2 (42% vs 11% p = 0.006). In multivariate analysis CHA2SD2VAS > 5 was an independent predictor of AF in patients with CS (HR 7.3 [95% CI 1.2-45.6] p = 0.032)
Conclusion
A CHA2DS2VASC score >5 is an independent predictor of AF in patients with CS. This score provides a new clinical tool to inform clinicians with regards to the optimal treatment of these challenging patients

Abstract
Abstract
Introduction
Cryptogenic stroke (CS) represents up to 30% of ischemic strokes. Since atrial fibrillation (AF) can be detected in up to one-third of CS, there is a clinical need for estimating the probability of underlying AF in CS to guide the optimal secondary prevention strategy.
Surrogate markers of left atrial dysfunction such as left atrial size, left atrial strain (LAS) and NTproBNP has been described as predictors of AF in patients with CS. However the evidence about AF markers in comprehensive and prospective studies in CS is still limited.
Purpose
The present study was designed to develop the first score to predict underlying AF in CS patients that includes markers of atrial dysfunction. To reach our aim we developed a comprehensive analysis including clinical, laboratory, electrocardiografic and advanced echocardiographic variables in patients with CS.
Methods
Sixty-three consecutive patients with ischemic stroke or transient ischemic attack with ABCD2 scale ≥4 of unknown etiology were prospectively recruited. Clinical, laboratory, electrocardiografic and echocardiographic variables were collected. All patients underwent 15 days wearable Holter monitoring. Main objective was the Decryptoring score creation to predict AF in CS. Score variables were initially selected by a univariate logistic regression and, thereafter, the score points were derived according to a multivariant analysis.
Results
AF was detected in 15 patients (24%). Patients in the AF group were older (81.4±6.9 vs 76.5±7.8 years; p=0.035. There was no difference in sex between groups. Regarding cardiovascular risk factors patients who developed AF had more often hypertension (87% vs 52%; p=0.018) without differences in diabetes, dyslipidemia and tobacco consumption. T troponin and NTproBNP were higher in the AF group (47±55.9 vs 16.8±12.4 ng/L; p=0.018 and 1379±1650 vs 317±496 ng/ml; p=0.001 respectively). There were no differences in ECG parameters such as p wave voltage, interatrial block, PR interval or QRS.
LAS reservoir, LAS conduct and LAS contraction were lower in patients with AF (18.6±4.6 vs 32.1±10.9%; 8±4.3 vs 15.6±8%; 10.5±3.4 vs 16.6±7 respectively, all p<0.001).
Age >75 (9 points), hypertension (1 point), Troponin T >40 ng/L (8.5 points), NTproBNP >200 pg/ml (0.5 points), LAS reservoir <25.3% (24.5 points) and LAS conduct <10.4% (0.5 points) were included in the score. The rate of AF detection was 0% among patients with a score of <10 and 80% among patients with a score >35.
Conclusion
The proposed score offers an accurate AF prediction in patients with CS providing a new clinical tool to orient the optimal treatment in these patients.

Abstract
Abstract
INTRODUCTION
Different difficulty factors have been described in rectal cancer surgery as BMI, male gender, tumor height, neoadjuvant treatment or narrow pelvis. Pelvimetry is not a routine preoperative study in rectal cancer.
MATERIAL AND METHODS
Retrospective observational study in 228 patients. Operative time was evaluated as a difficult surgical parameter and its relationship with pelvimetric variables was studied.
RESULTS
Our average operative time was 255,4 ± 65,8 minutes. Significant results were found with regard to patients’ BMI, distance to the anal margin, type of approach, need for neoadjuvant therapy and the following pelvimetry parameters. In the univariate analysis, the parameters were pubis height, pelvis depth, angle of the right levator in coronal plane, the ratio of the pelvis inlet diameter with respect to its depth, the ratio of the angle promontory-S3-coccyx with respect to the angle S3-coccyx-lower border of the pubis and the ratio of the area of the mesorectum to the area of the pelvis in the sagittal plane. In multivariate analysis, the variables that most influenced the surgical time were the type of approach, the BMI, the location of the tumor, the intraoperative complications and the ratio of the mesorectum area to the area of the pelvis in the sagittal plane.
CONCLUSION
Pelvimetry is a simple tool that completes preoperative studies and also obtains better surgical planning in complex pelvises.

DECRYPTORING study
Introduction
Cryptogenic stroke (CS) represents up to 30% of all stroke types. In one third of CS, atrial fibrillation (AF) is identified as the underlying cause. Predictors of AF in the setting of CS have been described, however these findings were based on retrospective studies and with maximum ECG monitoring of 72 hours. To overcome these limitations, we designed the prospective Decryptoring study whose objective is to create a comprehensive predictive model for AF in patients with CS.
Methods
From April 2019, 41 consecutive patients with a CS and age > 60 years were included. On admission, a transthoracic echocardiogram with 3D volume and left atrial (LA) strain was performed. All patients were monitored with a 15-day ECG-Holter after discharge. Patients were classified according to AF detection.
Results
AF was detected in 9 patients (22%). Patients with AF were older (75.9 ± 8 vs. 81.9 ± 4.3 years, p = 0.041). There was no difference in T-troponin levels. NTproBNP was higher in the group with AF (350 ± 586 pg / ml vs. 1084 ± 1416 pg / ml, p = 0.018). Regarding LA strain, patients with AF presented reservoir LA strain (25.5 ± 8.2% vs 17.4 ± 4.3%; p = 0.006) and conduct LA strain (12 ± 5.2% vs 7.2 ± 1.5%; p = 0.01) lower than patients without AF. There were no differences in contraction LA strain or other echocardiographic variables. The risk of developing AF was higher in patients with NTproBNP> 165 pg / ml (OR 11.3 [95% CI 1.2-102.9] p = 0.031), LA reservoir strain <19.1% (OR 7.7 [IC 95 % 1.5-40.0] p = 0.016) and LA conduct strain <9.1% (OR 7.8 [95% CI 1.3-45.0] p = 0.022) (Table).
Conclusions
This prospective study, demonstrates that high NTproBNP, low reservoir LA strain and low conduct LA strain are associated with underlying AF in patients with cryptogenic stroke.
No AF (n = 32) AF (n = 9) P value Age (years) 75.9 ± 8 81.9 ± 4.3 p = 0.041 NTPROBNP (pg/ml) 350 ± 586 1084 ± 1416 P = 0.018 LA indexed diastolic volume (ml/m2) 30 ± 11.8 33.8 ± 9.8 P = 0.35 LA EF (%) 45 ± 16.7 45 ± 12.8 P = 1 Reservoir LA strain (%) 25.5± 8.2 17.4± 4.3 P = 0.006 Conduct LA strain (%) 12 ± 5.2 7.2 ± 1.5 P = 0.01 Contraction LA strain (%) 13.5 ±5.3 10.2± 3.9 P = 0.10 NTPROBNP > 165 pg/ml 12 (41%) 8 (89%) OR 11.3 [IC 95% 1.2-102.9]; p = 0.031 Reservoir LA strain <19.1% 6 (20%) 6 (67%) OR 7.7 [IC 95% 1.5-40.0]; p = 0.016 Conduct LA strain <9.1% 9 (31%) 7 (78%) OR 7.8 [IC 95% 1.3-45.1]; p = 0.022

Abstract
The Alzheimer's Prevention Initiative (API) Autosomal Dominant Alzheimer's Disease (ADAD) trial evaluates the anti-amyloid-β antibody crenezumab in cognitively unimpaired persons who, based on genetic background and age, are at high imminent risk of clinical progression, and provides a powerful test of the amyloid hypothesis. The Neurosciences Group of Antioquia implemented a pre-screening process with the goals of decreasing screen failures and identifying participants most likely to adhere to trial requirements of the API ADAD trial in cognitively unimpaired members of Presenilin1 E280A mutation kindreds. The pre-screening failure rate was 48.2%: the primary reason was expected inability to comply with the protocol, chiefly due to work requirements. More carriers compared to non-carriers, and more males compared to females, failed pre-screening. Carriers with illiteracy or learning/comprehension difficulties failed pre-screening more than non-carriers. With the Colombian API Registry and our prescreening efforts, we randomized 169 30-60 year-old cognitively unimpaired carriers and 83 non-carriers who agreed to participate in the trial for at least 60 months. Our findings suggest multiple benefits of implementing a pre-screening process for enrolling prevention trials in ADAD.

Abstract
OBJECTIVE Gastroenteritic salmonellosis is still the second cause diagnosed of infectious diarrhea, most of these clinical pictures are mild and self-limited and therefore the use of antibiotics is limited to few cases. The aim of the study was to describe the episodes of diarrhea caused by Salmonella enterica subsp. enterica, assessing the suitability of the request and the use of antibiotics according to the criteria included in the methodology. METHODS A retrospective, descriptive, observational study was conducted, collecting data from the clinical history. RESULTS A total of 122 episodes were included. The reason for consultation was diarrhea, which generated a greater demand in the Hospital Emergency Services (42.6%). The most frequent serotypes isolated were Enteritidis (53.3%), and Typhimurium (40.2%). The adequate request of the stool was 90.2%. Antibiotic was prescribed in 64.6% (79) of the episodes, most patients under 65 years (58 episodes), the average age was 48.43 years. They were treated mainly with ciprofloxacin and azithromycin, in 57 and 14 episodes, respectively. The average duration of antibiotic treatment was 6 days. There was an adequate use of antibiotics in 49.1% of episodes. When the origin of the request was the Hospital Emergency Service, it was inadequate in 63.5% (33) of them. It was inadequate in 60.0% (39) of episodes when ser. Enteritidis was isolated. Almost half, 48.85% (42) of the 58 episodes in which antibiotics were prescribed among those under 65 (86), were treated without being indicated. CONCLUSIONS Training actions should be implemented focused on optimizing the management of antibiotics in this entity.

Abstract
Anaerobic digestion allows efficient treatment of high loaded wastewater, and membrane technology allows obtaining high quality effluents with complete biomass retention. However, high biomass concentration interferes with membrane fouling. In the present work, a new bioreactor that integrates an attached biomass anaerobic culture on a fixed bed and a submerged membrane has been started up. The recirculation between the digestion and filtration chambers is coupled to the gas-lift effect of the bubbling employed for the scouring of the membranes, avoiding the use or electromechanical pumps that damage the suspended biomass. The support material retains the biomass in the digestion tank despite the downwards flow, avoiding the submerged membrane contacting with a high concentrated suspension. This novel system, called an anaerobic filter membrane bioreactor was immediately started up, achieving chemical oxygen demand (COD) removal efficiencies of 96% at an organic loading rate (OLR) of 7 kg COD/m3·d. In order to select filtration flux, specific gas demand and filtration cycle duration, the results of 15 short term assays, eight hours for each one, is presented for fluxes between 15.7 and 17.7 L/m2·h, cycle duration between 10 and 30 minutes, and three levels of scouring. It was checked that reversible and irreversible fouling were directly related when dTMP/dt > 2.5 mbar/min.

Abstract
OBJECTIVE To evaluate if the cancer registry database can be used to monitor treatment effectiveness using nivolumab treatment of non-small cell lung cancer (NSCLC) as an example. METHOD An observational inception cohort was used, where all registered cases of NSCLC with authorisation to initiate treatment with nivolumab were monitored retrospectively to evaluate disease characteristics and response to prior treatments. Current exposure to nivolumab was prospectively characterised and treatment outcomes classified based on the clinical information registered in the patient medical record. The main outcome measure used to assess treatment effectiveness was overall survival (OS). Secondary outcomes considered were progression free survival (PFS) as a measure of effectiveness and occurrence of Adverse Drug Reaction (ADRs) as a measure of safety. Data were analysed using SPSS, version 24. RESULTS A total of 115 patients received treatment with nivolumab for NSCLC, between November 1st 2015 and July 31st 2016, and were registered in the database. The majority were non-squamous type (n=107). The median OS was 11.4 months {CI95%: 11.1-11.7}, with a 1-year survival of 44%, in line with clinical trial data. Median PFS was 5.4 months {CI95%: 2.8-7.9}. Treatment was discontinued in 82 cases, most frequently due to disease progression. There were 38 cases of ADRs documented in the patient medical chart, 21 of which led to treatment discontinuation. CONCLUSION The analysed data suggest that the cancer registry is a powerful tool to monitor treatment effectiveness, although considerable investment is needed to improve the medical culture of recording treatment exposure, particularly documentation of ADRs.

Abstract
OBJECTIVE The importance in human diarrhoeal disease of Hafnia alvei is unclear. The objective of the study was to describe the population which was isolated H. alvei in stool cultures and the therapeutic management of these cases in our Health Area. METHODS A descriptive retrospective study was carried out in 2014 and 2015. Epidemiological, clinical, treatment and evolution variables were collected in the computerized clinical history. RESULTS A collection of 7,290 stool specimens were processed, 3,321 in 2014 and 3,969 in 2015, of which 58 (1.7%) and 53 (1.3%) were positive for H. alvei, respectively. A 60.4% of samples were isolated in women. The mean age was 38.68 years. A 68.5% of samples were from primary care. In 71.2% there was related clinic, diarrhoea in 57.7%. In 75.7% of the cases there was not associated underlying disease. A 43.2% of the cases received treatment. A 66.7% of treated patients came from Primary Care. The mean duration of treatment was 8 days. The evolution was favourable in 85.4% of the cases treated. All strains were susceptible to ciprofloxacin and trimethoprim/sulfamethoxazole. CONCLUSIONS More evidence is needed to support H. alvei as a cause of gastroenteritis.

Abstract
OBJECTIVE The human papillomavirus (HPV), is necessary to cause a woman developing cervical cancer. The aim of the study was to estimate the prevalence of women with HPV infection, covered by the program of prevention and early detection of cervical cancer of Castile and León (Spain). METHODS Samples of women included in the screening program were analyzed. Including a total of 120,326 cervical swab samples, collected in the period from January 2012 to December 2014. RESULTS 12,183 HPV positive samples were detected, representing a prevalence of 9.6 ‰, (IC 95% 9.5%-9.8%) in the female population. High-risk HPV were found in higher proportion that HPV low-risk genotypes. HPV prevalence correlates inversely with women age. Coinfections of multiple genotypes were found in one third of screened women population. CONCLUSIONS Data showed in this study are the first and wider Spanish results from a cervical cancer screening program population non opportunistic based on HPV detection. These results would serve as a reference for future prevalence studies and to evaluate the future impact of HPV vaccination campaigns.

Abstract
The effect of blanching and frozen storage on the stability of pigments β-carotene and capsanthin in three cultivars of red pepper (Capsicum annuum) fruits was elucidated by the determination of pigments in samples treated by various blanching procedures. Pigment concentration was performed after different storage times by HPLC. The dependence of the concentration of pigments on the conditions of blanching and the storage time was assessed by stepwise regression analysis, and the similarities and dissimilarities among the cultivars and decomposition rates were calculated by principal component analysis. The stability of pigments depended significantly on the conditions of blanching, the storage time and the type of cultivar, the effect of storage time was higher than that of blanching conditions. The significant differences between the decomposition rate of pigments in various cultivars emphasizes the predominant importance of the selection of cultivars with advantageous storage characteristics.

Abstract
Obesity and emphysema are associated with low-grade systemic inflammation and oxidant stress. Assuming that the oxidant stress induced by emphysema would be decreased by obesity, we analyzed the oxidant/antioxidant state in a rat model combining both diseases simultaneously. Obesity was induced using sucrose, while emphysema by exposure to tobacco smoke. End-points evaluated were: body weight, abdominal fat, plasma dyslipidemia and malondialdehyde (MDA), insulin and glucose AUC, activities of Mn-superoxide dismutase (Mn-SOD), glutathione reductase (GR), glutathione transferase (GST) and glutathione peroxidase (GPx); lung MnSOD and 3-nitrotyrosine (3-NT) immunostaining, and expression of αV and β6 integrin subunits. In rats with obesity, the body weight, abdominal fat, plasma triglyceride levels, glucose AUC, insulin levels, GST activity, and αV and β6 integrin expressions were amplified. The rats with emphysema had lower values of body weight, abdominal fat, plasma insulin, triglycerides and glucose AUC but higher values of plasma MDA, GPx activity, and the lung expression of the αV and β6 integrins. The combination of obesity and emphysema compared to either condition alone led to diminished body weight, abdominal fat, plasma insulin MDA levels, GPx and GST activities, and αV and β6 integrin expressions; these parameters were all previously increased by obesity. Immunostaining for MnSOD augmented in all experimental groups, but the staining for 3-NT only increased in rats treated with tobacco alone or combined with sucrose. Results showed that obesity reduces oxidant stress and integrin expression, increasing antioxidant enzyme activities; these changes seem to partly contribute to a protective mechanism of obesity against emphysema development.

Abstract
BACKGROUND Heroin and its contaminants may be an important source of allergens in young people. We present a case of severe endophthalmitis in a patient that also suffered from anaphylactoid symptoms (hypotension, urticaria, glottic oedema) whenever he ingested lemon. METHODS Prick tests with a battery of 42 aeroallergens including fruits and citrus fruits (orange, mandarin, grapefruit and lemon) and specific IgE to these allergens were carried out. Immunodetection was performed using the patient's serum and the following allergens: lemon, Candida, Aspergillus, Penicillium and Alternaria recombinant Alt 1 (Laboratories Diater). RESULTS Skin tests were negative for Candida, Penicillium, Aspergillus and Cladosporium (ALK-Spain) as were specific IgE antibodies for CAP (Thermofisher, Sweden) and positive only for lemon and, doubtfully, to Candida. Specific IgE tests to pollen, arthropods, fungi, dander and foods were positive only for lemon (0.49kU/L). Serological study of fungi ruled out fungal infection at that time. The immunodetection showed that the patient's serum recognised a protein of approximately 25kDa of lemon peel, one of approximately 12-13kDa of Penicillium, and perfectly recognised Alt a 1. CONCLUSIONS Lemon surface can be contaminated by Candida and other fungi. In heroin addicts with positive skin tests for lemon, the possibility of these serious complications should be taken into account.

Abstract
Bacillus amyloliquefaciens CECT 8237 and CECT 8238, formerly known as Bacillus subtilis UMAF6639 and UMAF6614, respectively, contribute to plant health by facing microbial pathogens or inducing the plant's defense mechanisms. We sequenced their genomes and developed a set of ad hoc scripts that allowed us to search for the features implicated in their beneficial interaction with plants. We define a core set of genes that should ideally be found in any beneficial Bacillus strain, including the production of secondary metabolites, volatile compounds, metabolic plasticity, cell-to-cell communication systems, and biofilm formation. We experimentally prove that some of these genetic elements are active, such as i) the production of known secondary metabolites or ii) acetoin and 2-3-butanediol, compounds that stimulate plant growth and host defense responses. A comparison with other Bacillus genomes permits us to find differences in the cell-to-cell communication system and biofilm formation and to hypothesize variations in their persistence and resistance ability in diverse environmental conditions. In addition, the major protection provided by CECT 8237 and CECT 8238, which is different from other Bacillus strains against bacterial and fungal melon diseases, permits us to propose a correlation with their singular genetic background and determine the need to search for additional blind biocontrol-related features.

Abstract
Severe aplastic anemia (SAA) is a rare disorder leading to bone marrow failure, which if left untreated, is invariably fatal. Conventional therapies with immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation (HSCT) are highly effective. HSCT can offer a greater outcome in younger patients who have an available HLA match-related donor. Recent studies showing the addition of antithymocyte globulin (ATG) to the conditioning regimen improves engraftment and reduces the risk of graft-versus-host disease (GVHD).There are currently two ATG preparations in the USA, equine (or horse) and rabbit ATG. These agents are pharmacologically distinct, having significant differences in their pharmacokinetics and in vivo immunosuppressive effects [N Engl J Med 365(5):430–438, 2011]. Here, we report a case of two monozygotic twins with constitutional SAA that evolved to myelodysplastic syndrome (MDS) who both underwent allogeneic peripheral blood stem cell transplantation (PBSC) from the same single HLA antigen mismatched sibling donor with the only difference in the transplant regimen being the type of ATG used in the preparative regimen; one twin received horse ATG and the other received rabbit ATG during conditioning. This report emphasizes that dramatic differences in donor T cell chimerism and clinical outcomes including GVHD can occur as a consequence of the type of ATG that is utilized in the transplant conditioning regimen. These differences highlight that these agents should not be considered interchangeable drugs when used in this setting.

OBJECTIVES The main objective of the present study is to analyze different genotypic and phenotypic traits related to virulence in Enterococcus faecalis, as well as evaluated the agar invasion phenotype in a collection of isolates with different clinical origins. MATERIAL AND METHODS Seventy-nine E. faecalis isolates, with invasive and non-invasive clinical origins, have been used in this work. Presence of cytolysin activator (cylA), gelatinase (gelE), surface protein (esp), aggregation substance (asa1), endocarditis antigen (efaA), and collagen-binding protein (ace) have been analyzed by PCR. Phenotypic characterization included gelatinase activity, haemolysin production, biofilm formation and agar invasion. RESULTS All the isolates tested harboured at least one of the virulence determinants. The 95.5% of isolates from haematologic samples were positive for agar invasion test, significantly higher than isolates from non-invasive diseases. A significant reduction in relative invasion area was observed in three selected agar-invasive strains after 15 serial passages. CONCLUSIONS It has been observed a significant high prevalence of agar-invasion positive isolates among strains belonged to haematological samples. Agar invasiveness is reduced after adaptation of clinical isolates to laboratory conditions, showing that agar invasion phenotype can be modulate by culture conditions as other virulence factors observed in different bacterial species.
