Laparoscopic cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: Long term oncologic outcomes from the international PSOGI registry. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107001. [PMID: 37579618 DOI: 10.1016/j.ejso.2023.107001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 07/07/2023] [Accepted: 07/29/2023] [Indexed: 08/16/2023]
Abstract
The laparoscopic approach for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (L-CRS + HIPEC) in highly selected patients was previously reported from the PSOGI registry with a demonstrable reduction in length of stay and post-operative morbidity. This study aims to update this international PSOGI registry with a larger cohort of patients and a longer follow-up period. METHODS An international registry was designed through a networking database (REDCAP®). All centers performing L-CRS + HIPEC were invited through PSOGI to submit data on their cases. Variables such as demographics, clinical outcomes, and survival were analyzed. RESULTS A total of 315 L-CRS + HIPEC cases were provided by 14 worldwide centers. A total of 215 patients were included in the L-CRS + HIPEC group. The median peritoneal cancer index (PCI) was 3 (3-5). The median length of stay was 7 days (5-10) and the major morbidity (Clavien-Dindo ≥3) was 6.1% after 30 days. The 5-year disease-free survival (DFS) per tumor origin was: 94% for PMP-LG, 85% for PMP-HG, 100% for benign multicyst peritoneal mesothelioma (MPM), 37.4% for colonic origin, and 54%(at 3 years) for ovarian origin. The 5 years overall survival (OS) per tumor origin was: 100% for PMP-LG, PMP-HG and MPM; 61% for colonic origin, and 74% (at 3 years) for ovarian origin. In addition, a total of 85 patients were analyzed in the laparoscopic risk-reducing HIPEC (L-RR + HIPEC). The median length of stay was 5 days (4-6) and the major morbidity was 6% after 30 days. The 5-year DFS per tumor origin was: 96% for perforated low grade appendiceal mucinous neoplasm (LAMN II) and 68.1% for colon origin. The 5 years OS per tumor origin was: 98% for LAMN II and 83.5% for colonic origin. CONCLUSIONS Minimally invasive CRS + HIPEC is a safe procedure for selected patients with peritoneal carcinomatosis in specialized centers. It improves perioperative results while providing satisfactory oncologic outcomes. L-RR + HIPEC represents a promising strategy that could be evaluated in patients with high risk of developing peritoneal carcinomatosis into prospective randomized trials.

Abstract
We present an update of the 2020 Recommendations on neuromuscular blockade of the SEDAR. The previous ones dated 2009. A modified Delphi consensus analysis (experts, working group, and previous extensive bibliographic revision) 10 recommendations were produced1: neuromuscular blocking agents were recommended for endotracheal intubation and to avoid faringo-laryngeal and tracheal lesions, including critical care patients.2 We recommend not to use neuromuscular blocking agents for routine insertion of supraglotic airway devices, and to use it only in cases of airway obstruction or endotracheal intubation through the device.3 We recommend to use a rapid action neuromuscular blocking agent with an hypnotic in rapid sequence induction of anesthesia.4 We recommend profound neuromuscular block in laparoscopic surgery.5 We recommend quantitative monitoring of neuromuscular blockade during the whole surgical procedure, provided neuromuscular blocking agents have been used.6 We recommend quantitative monitoring through ulnar nerve stimulation and response evaluation of the adductor pollicis brevis, acceleromyography being the clinical standard.7 We recommend a recovery of neuromuscular block of at least TOFr ≥ 0.9 to avoid postoperative residual neuromuscular blockade.8 We recommend drug reversal of neuromuscular block at the end of general anesthetic, before extubation, provided a TOFr ≥ 0.9 has not been reached.9 We recommend to choose anticholinesterases for neuromuscular block reversal only if TOF≥2 and a TOFr ≥ 0.9 has not been attained.10 We recommend to choose sugammadex instead of anticholinesterases for reversal of neuromuscular blockade induced with rocuronium.

Abstract
This review compiled and analyzed the operational conditions (dissolved oxygen, feast and famine ratio, sequential batch reactor cycle length, organic loading rate (OLR), pH, C/N, and temperature) established during the feast and famine culture strategy for the mixed microbial cultures (MMC) selection to understand how these variables could affect the synthesis of polyhydroxyalkanoates, polyglucose, triacylglycerides, levulinic acid and adipic acid from non-fermented substrates. According to the reported information, the dissolved oxygen has a greater impact on the type and amount of produced compound. In a lesser extent, the OLR and the cycle length were identified to have an impact on the accumulation of polyhydroxyalkanoates, whose accumulation was favored at lower OLR and longer cycle lengths. Thereby, the information of this work will allow the design of future strategies for the simultaneous accumulation of compounds of interest other than the polyhydroxyalkanoates or understand the operational conditions that would optimize the polyhydroxyalkanoates production.

Abstract
Genetic resistance is the most recommended measure to control verticillium wilt in olive (VWO), a vascular disease caused by the soil-borne fungus Verticillium dahliae, which has promoted the development of olive breeding programs aimed at obtaining new resistant and highly yielding cultivars in recent years. Screening has been commonly performed under controlled conditions in grow chamber after artificial inoculation during the early stage of breeding programs, but additional evaluation is necessary to confirm previous results as well as to test for additional agronomic traits. During this study, 20 breeding selections initially classified as resistant to the disease have been re-evaluated in artificially infested soils under natural environmental conditions. The maximum disease incidence (52.6%) was reached at 26 months after planting, and the disease intensity index reached the maximum value of 38.5% at 29 months after planting. Nine breeding selections consistently confirmed the previous results regarding resistance to V. dahliae infection; however, contradictory results, compared with those of previous evaluations under controlled conditions in grow chambers, were obtained for the rest of selections tested, thereby underlining the need for long-term experimentation under natural environmental conditions. Additional positive agronomic traits, such as early bearing, were also observed for some of the resistant selections, but plant vigor varied. Some seem highly promising for release as new cultivars when characterization of other important agronomic traits is completed in the future.

Abstract
Prognosis for relapsed or refractory (R/R) acute myeloid leukemia (AML) despite salvage therapy is dismal. This phase I dose-escalation trial assessed the safety and preliminary clinical activity of selinexor, an oral exportin-1 (XPO1) inhibitor, in combination with FLAG-Ida in younger R/R AML patients. The aim was to find the recommended phase 2 dose (RP2D) and maximum tolerated dose (MTD). Fourteen patients were included, and selinexor dosage was 60 mg (3 patients), 80 mg (3 patients), and 100 mg (7 patients) weekly. No dose-limiting toxicities were reported. Grade ≥3 non-hematologic adverse events (AEs) occurred in 78.6% of patients. Two patients were non MTD evaluable due to early death, and overall, 3 out of 14 patients (21.4%) had fatal AEs. Five out of 12 (42%) response and MTD evaluable patients achieved a complete remission (CR; n=4) or CR with incomplete hematologic recovery (CRi, n=1), and 4 patients (33%) subsequently underwent allogeneic transplantation. The median overall survival (OS) and event-free survival (EFS) were 6.0 (range 0.9-19.3) and 1.1 months (range 0.7-19.3), respectively. Using selinexor 100 mg/weekly, CR/CRi rate of 66.7%, OS 13.6 months (range, 1.6-19.3), and EFS 10.6 months (range, 0.9-19.3). At last follow-up, 3 patients were alive. Selinexor 100 mg/weekly with FLAG-Ida combination in R/R AML showed acceptable tolerability and efficacy, establishing the RP2D of this regimen in future clinical trials.

Metabolic syndrome during gestation and lactation: An important renal problem in dams. selenium renal clearance. J Trace Elem Med Biol 2021; 64:126709.

Abstract
BACKGROUND Metabolic syndrome (MS) in lactating dams leads to several cardiometabolic changes related to selenium (Se) status and selenoproteins expression which produce hypertension. However, little is known about the state of these dams' kidney functions and their Se deposits. METHODS Two experimental groups of dam rats were used: control (Se: 0.1 ppm) and MS (Fructose 65 % and Se: 0.1 ppm). At the end of lactation (21d postpartum) kidney weight and protein content, Se deposits, and the activity of the antioxidant selenoprotein glutathione peroxidase (GPx) were measured in dams. Kidney functional parameters: albuminuria, creatinine clearance, serum aldosterone and uric acid levels and water and electrolyte (Na+ and K+) balance were also evaluated. Systolic blood pressure (SBP) was measured. RESULTS In MS dams at the end of lactation Se deposits and GPx activity are higher in the kidney; however, lipid renal peroxidation appears, relative Se clearance increases, and the dams have lost Se by urine. MS dams have polyuria and polydipsia, high uric acid serum levels, albuminuria and high creatinine clearance, implying glomerular renal malfunction with protein loss. They also present hypernatremia, hypokalemia and hyperaldosteronemia, leading to high SBP; however, a natriuretic process is taking place. CONCLUSION Since these alterations appear, at least in part, to be related to oxidative stress in renal cells, Se supplementation could be beneficial to avoiding greater lipid renal oxidation during lactation.

Abstract
BACKGROUND Options to treat elderly patients (≥65 years old) newly diagnosed with acute myeloid leukemia (AML) include intensive and attenuated chemotherapy, hypomethylating agents with or without venetoclax, and supportive care. This multicenter, randomized, open-label, phase 3 trial was designed to assess the efficacy and safety of a fludarabine, cytarabine, and filgrastim (FLUGA) regimen in comparison with azacitidine (AZA). METHODS Patients (n = 283) were randomized 1:1 to FLUGA (n = 141) or AZA (n = 142). Response was evaluated after cycles 1, 3, 6, and 9. Measurable residual disease (MRD) was assessed after cycle 9. When MRD was ≥0.01%, patients continued with the treatment until relapse or progressive disease. Patients with MRD < 0.01% suspended treatment to enter the follow-up phase. RESULTS The complete remission (CR) rate after 3 cycles was significantly better in the FLUGA arm (18% vs 9%; P = .04), but the CR/CR with incomplete recovery rate at 9 months was similar (33% vs 29%; P = .41). There were no significant differences between arms in early mortality at 30 or 60 days. Hematologic toxicities were more frequent with FLUGA, especially during induction. The 1-year overall survival (OS) rate and the median OS were superior with AZA versus FLUGA: 47% versus 27% and 9.8 months (95% confidence interval [CI], 5.6-14 months) versus 4.1 months (95% CI, 2.7-5.5 months; P = .005), respectively. The median event-free survival was 4.9 months (95% CI, 2.8-7 months) with AZA and 3 months (95% CI, 2.5-3.5 months) with FLUGA (P = .001). CONCLUSIONS FLUGA achieved more remissions after 3 cycles, but the 1-year OS rate was superior with AZA. However, long-term outcomes were disappointing in both arms (3-year OS rate, 10% vs 5%). This study supports the use of an AZA backbone for future combinations in elderly patients with AML.

Abstract
The application of thermal pretreatments to facilitate its anaerobic digestion has associated phenols and furans production, which are commonly identified as inhibitory compounds. Phenols and furans extraction can be done from a liquid phase produced after the thermal pretreatment. In the present study this dephenolized liquid phase (DLP) showed an increase of 42% in methane yield compared to the raw liquid phase (LP) demonstrating the inhibitor character of such compounds. The main extracted phenols and furans were: 3,4-Dihydroxyphenylglycol (DHPG), Hydroxytyrosol (HT), Tyrosol (Ty), Vanillic acid (AcV), Hydroxymethylfurfural (HMF), Vanillin (V) and Furfural (F).This study also aimed to evaluate the individual effect on methane production of these specific phenols and furans the within the mixture of several ones from LP. The evaluation of the individual compounds over the methanogenesis of a dephenolized liquid phase showed that only V was inhibitory on both methane yield and methane production rate. HMF had a significantly negative effect on methane yield, but improved the methane production rate instead. Ty, F, DHPG and HT favoured the methane yield and production rate. Additionally, it was observed that negative effect of some individual phenols and furans was counteracted by the positive effect of other compounds.

Abstract
The infection by the coronavirus SARS-CoV-2, which causes the disease called COVID-19, mainly causes alterations in the respiratory system. In severely ill patients, the disease often evolves into an acute respiratory distress syndrome that can predispose patients to a state of hypercoagulability, with thrombosis at both venous and arterial levels. This predisposition presents a multifactorial physiopathology, related to hypoxia as well as to the severe inflammatory process linked to this pathology, including the additional thrombotic factors present in many of the patients. In view of the need to optimise the management of hypercoagulability, the working groups of the Scientific Societies of Anaesthesiology-Resuscitation and Pain Therapy (SEDAR) and of Intensive, Critical Care Medicine and Coronary Units (SEMICYUC) have developed a consensus to establish guidelines for actions to be taken against alterations in haemostasis observed in severely ill patients with COVID-19. These recommendations include prophylaxis of venous thromboembolic disease in these patients, and in the peripartum, management of patients on long-term antiplatelet or anticoagulant treatment, bleeding complications in the course of the disease, and the interpretation of general alterations in haemostasis.

Magnetosomes could be protective shields against metal stress in magnetotactic bacteria. Sci Rep 2020; 10:11430.

Abstract
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic compass, allowing the bacteria to align in and navigate along the Earth’s magnetic field lines. According to the magneto-aerotactic hypothesis, the purpose of producing magnetosomes is to provide the bacteria with a more efficient movement within the stratified water column, in search of the optimal positions that satisfy their nutritional requirements. However, magnetosomes could have other physiological roles, as proposed in this work. Here we analyse the role of magnetosomes in the tolerance of Magnetospirillum gryphiswaldense MSR-1 to transition metals (Co, Mn, Ni, Zn, Cu). By exposing bacterial populations with and without magnetosomes to increasing concentrations of metals in the growth medium, we observe that the tolerance is significantly higher when bacteria have magnetosomes. The resistance mechanisms triggered in magnetosome-bearing bacteria under metal stress have been investigated by means of x-ray absorption near edge spectroscopy (XANES). XANES experiments were performed both on magnetosomes isolated from the bacteria and on the whole bacteria, aimed to assess whether bacteria use magnetosomes as metal storages, or whether they incorporate the excess metal in other cell compartments. Our findings reveal that the tolerance mechanisms are metal-specific: Mn, Zn and Cu are incorporated in both the magnetosomes and other cell compartments; Co is only incorporated in the magnetosomes, and Ni is incorporated in other cell compartments. In the case of Co, Zn and Mn, the metal is integrated in the magnetosome magnetite mineral core.

Abstract
Self-sustaining smouldering combustion (SSS) is a technology based on the flameless oxidation of an organic substrate and limited by the rate at which oxygen is diffused to the surface of the substrate. This work aims to evaluate the SSS combustion as a treatment process for the stabilization of anaerobic digestate, determining the limits of operational conditions, (moisture content (MC), air flux) that allow for a self-sustaining process. Maximum possible MC was found at 82 wt% with Darcy air flux of 50 cm/s. The digestate destruction rate (kg/(h·m2), and the addition of sand as an inert solid, to enhance the oxygen diffusion, were also investigated. A sand/substrate mass ratio of 1 allowed for SSS at 85 wt% MC, but decreased the digestate destruction rate. The average composition of the emitted gases showed ca. 25% CO and 10% H2, whereas the analysis of the ashes showed almost complete digestate inertization.

BACKGROUND The treatment of acute lymphoblastic leukemia (ALL) in older adults and elderly patients is a challenge, and modern protocols include targeted therapy and immunotherapy in combination with attenuated or minimal chemotherapy. However, frail patients are excluded from these trials, and reports on the outcome of this subgroup of patients are scarce. Our objective was to analyze the outcome of unfit older adults and elderly patients with Philadelphia chromosome-negative ALL included in a prospective trial (ALL-07FRAIL). PATIENTS AND METHODS Older adults and elderly patients with Charlson Comorbidity Index (CCI) ≥ 4 were included. Induction therapy consisted of vincristine and dexamethasone, and maintenance therapy with mercaptopurine and methotrexate for 2 years. RESULTS Seventy-two patients with a median age of 67 years (range, 57-89 years) and a median CCI of 5 (range, 4-12) were included. The rates of early withdrawal, early death, resistance, and complete response (CR) were 5%, 10%, 31%, and 54%, respectively. Six patients with CR abandoned the study, 5 died in CR, and 23 relapsed (cumulative relapse incidence 75%). The medians of disease-free and overall survival (OS) were 6.9 months (95% confidence interval [CI], 0.3-13.5 months) and 7.6 months (95% CI, 6.3-8.9 months), respectively. The most frequent toxic events were hematologic (neutropenia 77% and thrombocytopenia 54%, of grade III-IV in all cases). Eastern Cooperative Oncology Group score but not the CCI had significant impact on OS. CONCLUSION Complete remission with very attenuated chemotherapy can be attained in one-half of older or elderly infirm patients with ALL. These results suggest that some of these patients could benefit from the concomitant or subsequent use of immunotherapy and/or targeted therapy.

Impact of intermittent voluntary ethanol consumption during adolescence on the expression of endocannabinoid system and neuroinflammatory mediators. Eur Neuropsychopharmacol 2020; 33:126-138. [PMID: 32057593 DOI: 10.1016/j.euroneuro.2020.01.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 01/09/2020] [Accepted: 01/22/2020] [Indexed: 01/14/2023]
Abstract
The adolescent brain displays high vulnerability to the deleterious effects of ethanol, including greater risk of developing alcohol use disorder later in life. Here, we characterized the gene expression of the endocannabinoid system (ECS) and relevant signaling systems associated with neuroinflammation and emotional behaviors in the brain of young adult control and ethanol-exposed (EtOH) rats. We measured mRNA levels of candidate genes using quantitative real time PCR in the medial prefrontal cortex (mPFC), amygdala and hippocampus. EtOH rats were generated by maintenance on an intermittent and voluntary ethanol consumption during adolescence using the two-bottle choice paradigm (4 days/week for 4 weeks) followed by 2 week-withdrawal, a time-point of withdrawal with no physical symptoms. Mean differences and effect sizes were calculated using t-test and Cohen's d values. In the mPFC and hippocampus, EtOH rats had significantly higher mRNA expression of endocannabinoid-signaling (mPFC: Ppara, Dagla, Daglb and Napepld; and hippocampus: Cnr2, Dagla and Mgll) and neuroinflammation-associated genes (mPFC: Gfap; and hippocampus: Aif1) than in controls. Moreover, EtOH rats had significantly higher mRNA expression of neuropeptide Y receptor genes (Npy1r, Npy2r and Npy5r) in the hippocampus. Finally, EtOH rats also displayed higher plasma endocannabinoid levels than controls. In conclusion, these results suggest that adolescent ethanol exposure can lead to long-term alterations in the gene expression of the ECS and other signaling systems involved in neuroinflammation and regulation of emotional behaviors in key brain areas for the development of addiction.

Elevation of serum ferritin levels for predicting a poor outcome in hospitalized patients with influenza infection. Clin Microbiol Infect 2020; 26:1557.e9-1557.e15. [PMID: 32120038 DOI: 10.1016/j.cmi.2020.02.018] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Revised: 02/05/2020] [Accepted: 02/14/2020] [Indexed: 01/04/2023]
Abstract
OBJECTIVES There is increasing evidence that ferritin is a key marker of macrophage activation, but its potential role in influenza infection remains unexplored. Our aim was to assess whether hyperferritinaemia (ferritin ≥500 ng/mL) could be a marker of poor prognosis in hospitalized patients with confirmed influenza A infection. METHODS We prospectively recruited all hospitalized adult patients who tested positive for the influenza A rRT-PCR assay performed on respiratory samples in two consecutive influenza periods (2016-17 and 2017-18). Poor outcome was defined as the presence of at least one of the following: respiratory failure, admission to the intensive care unit, or in-hospital mortality. RESULTS Among 494 patients, 68 (14%) developed poor outcomes; 112 patients (23%) had hyperferritinaemia (39/68, 57% in the poor-outcome group versus 73/426, 17% in the remaining patients, p < 0.0001). Median serum ferritin levels were significantly higher in the subgroup of patients with poor outcomes (609 ng/mL, range 231-967 versus 217 ng/mL, range 140-394, p < 0.0001). In multivariate analysis, hyperferritinaemia was associated with a five-fold increase in the odds ratio of developing poor outcome. After adjusting for classic influenza risk factors, ferritin remained as a significant predictive factor in all exploratory models. Ferritin levels had a good discriminative capacity with an area under the ROC curve of 0.72 (95% confidence interval (CI) 0.65-0.8, p < 0.001) and an overall diagnostic accuracy for predicting poor outcome of 79.3% (95%CI 75.4-82.7%). CONCLUSIONS Serum ferritin may discriminate a subgroup of patients with influenza infection who have a higher risk of developing a poor outcome.

Abstract
OBJECTIVE The aim of this study is to prove the effectiveness of a low cost, artificial model for training of a laparoscopic urethrovesical anastomosis. MATERIALS AND METHODS This study included urologists who attended specialised courses on laparoscopic radical prostatectomy (LRP) held during the period 2015 to 2017. They were divided into 2 groups according to their previous experience in laparoscopic surgery. The tasks performed on the artificial simulator were prostate resection, "task 1", and urethrovesical anastomosis, "task 2". Once these exercises were completed, the study participants filled in an anonymous questionnaire regarding their demographic data and experience level in laparoscopic surgery (LS). In addition, they gave their opinions about the didactic capacity of the artificial organ and evaluated its usefulness as a tool for LRP training. To demonstrate face and content validity, the participants judged the texture, consistency, morphology and evaluated its similarity to the real organ. The assessment was made with a five-point Likert scale. RESULTS The students were divided into 2groups: 10 experts (Group E) and 12 novices (Group N). The only significant difference between the scores of novices and experts was regarding the inclusion of this tool in the training programs (Group E=5 points versus group N=4.4±0.59, P=.024). The experts' group rated all the items with higher scores than the novices' one. Regarding the general assessment of the simulation model, the novice participants gave an average score of 8.00±0.91 points out of 10, while the experts' group granted higher scores of 9.4±0,51. CONCLUSION This artificial model has shown to have an elevated face, content and construct validity, as well being an optimal didactic tool for training in the techniques of prostate resection and laparoscopic urethrovesical anastomosis.

Self-assembly of iron oxide precursor micelles driven by magnetic stirring time in sol-gel coatings. RSC Adv 2019; 9:17571-17580.

Abstract
The purpose of this work is to fabricate self-assembled microstructures by the sol–gel method and study the morphological, structural and compositional dependence of ε-Fe2O3 nanoparticles embedded in silica when glycerol (GLY) and cetyl-trimethylammonium bromide (CTAB) are added as steric agents simultaneously. The combined action of a polyalcohol and a surfactant significantly modifies the morphology of the sample giving rise to a different microstructure in each of the studied cases (1, 3 and 7 days of magnetic stirring time). This is due to the fact that the addition of these two compounds leads to a considerable increase in gelation time as GLY can interact with the alkoxide group on the surface of the iron oxide precursor micelle and/or be incorporated into the hydrophilic chains of CTAB. This last effect causes the iron oxide precursor micelles to be interconnected forming aggregates whose size and structure depend on the magnetic stirring time of the sol–gel synthetic route. In this paper, crystalline structure, composition, purity and morphology of the sol–gel coatings densified at 960 °C are examined. Emphasis is placed on the nominal percentage of the different iron oxides found in the samples and on the morphological and structural differences. This work implies the possibility of patterning ε-Fe2O3 nanoparticles in coatings and controlling their purity by an easy one-pot sol–gel method.

Rabbit manure as a potential inoculum for anaerobic digestion. JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH. PART A, TOXIC/HAZARDOUS SUBSTANCES & ENVIRONMENTAL ENGINEERING 2019; 54:943-950.

Abstract
The potential of using rabbit manure as inoculum for biogas production was evaluated through batch assays using bean straw as substrate. The microbial diversity in the rabbit manure included lignin-degrading bacteria (classes Bacteroidia, Bacilli and Clostridia) as well as key acetoclastic (Matheanosarcina and Methanosaeta), and hydrogenotrophic (Methanobacterium, Methanolinea, and Methanovebribacter) archaea. The effects of particle size, substrate to inoculum ratio (S/X) and pH adjustment were studied to improve the inoculum activity. The adjustment of the pH entailed the highest improvement in methane production (515%) and rate (164%). However, high S/X, (3-4), resulted in the acidification of the processes, denoting an imbalance between hydrolytic bacteria and methanogenic archaea in the rabbit manure. This confirmed that the use of rabbit manure as inoculum could sustain anaerobic digestion from agricultural residues, although a proper enrichment and adaptation is necessary to ensure an appropriate methane production.

Effects of barium on the pathways of anaerobic digestion. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2019; 232:397-403.

Abstract
The sufficient presence of trace elements (TE) is essential for anaerobic digestion. Barium (Ba) is considered a non-essential trace element that can be collaterally added to digesters as part of low-cost trace element sources or because of its presence in some feedstocks, such as crude glycerol. In the present study, the impact of Ba supplementation (2-2000 mg/L) on each stage of the anaerobic digestion (AD) process was evaluated using pure substrates (i.e., cellulose, glucose, a mixture of volatile fatty acids, sodium acetate and hydrogen) as well as a complex substrate (i.e., dried green fodder). Hydrolytic activity was affected at dosages higher than 200 mg Ba/L, whereas cellulose degradation was completely inhibited at 2000 mg Ba/L. The negative effects of the addition of Ba to methane production were observed only in the hydrolytic activity, and no effects were detected at any barium dosage in the subsequent anaerobic steps. Because Ba does not have a reported role as a cofactor of enzymes, this response could have been due to a direct inhibitory effect, a variation in the bioavailability of other trace elements, or even the availability of CO2/SO4 through precipitation as Ba-carbonates and sulphates. The results showed that the addition of Ba modified the chemical equilibrium of the studied system by varying the soluble concentration of some TEs and therefore their bioavailability. The highest variation was detected in the soluble concentration of zinc, which increased as the amount of Ba increased. Although little research has shown that Ba has some utility in anaerobic processes, its addition must be carefully monitored to avoid an undesirable modification of the chemical equilibrium in the system.

Abstract
AIM To explore the cooperation of GLP-1 receptor and β3-adrenergic receptor (β3-AR)-mediated signalling in the control of fat mass/feeding behaviour by studying the effects of a combined therapy composed of the GLP-1R agonist liraglutide and the β3-AR agonist CL316243. METHODS The study included the analysis of key mechanisms regulating lipid/cholesterol metabolism, and thermogenesis in brown (BAT) and epididymal white (eWAT) adipose tissues, abdominal muscle and liver of male rats. RESULTS CL316243 (1 mg kg-1 ) and liraglutide (100 μg kg-1 ) co-administration over 6 days potentiated an overall negative energy balance (reduction in food intake, body weight gain, fat/non-fat mass ratio, liver fat content, and circulating levels of non-essential fatty acids, triglycerides, very low-density lipoprotein-cholesterol and leptin). These effects were accompanied by increased plasma levels of insulin and IL6. We also observed increased gene expression of uncoupling proteins regulating thermogenesis in BAT/eWAT (Ucp1) and muscle (Ucp2/3). Expression of transcription factor and enzymes involved either in de novo lipogenesis (Chrebp, Acaca, Fasn, Scd1, Insig1, Srebp1) or in fatty acid β-oxidation (Cpt1b) was enhanced in eWAT and/or muscle but decreased in BAT. Pparα and Pparγ, essentials in lipid flux/storage, were decreased in BAT/eWAT but increased in the muscle and liver. Cholesterol synthesis regulators (Insig2, Srebp2, Hmgcr) were particularly over-expressed in muscle. These GLP-1R/β3-AR-induced metabolic effects were associated with the downregulation of cAMP-dependent signalling pathways (PKA/AKT/AMPK). CONCLUSION Combined activation of GLP-1 and β3-ARs potentiate changes in peripheral pathways regulating lipid/cholesterol metabolism in a tissue-specific manner that favours a switch in energy availability/expenditure and may be useful for obesity treatment.

Abstract
Abstract
Introduction: Germline testing for BRCA1/2 genes provides an opportunity to reduce mortality and morbidity by adopting appropriate risk reduction and screening options, in particular with risk-reducing bilateral salpingo-oophorectomy (BSO).There is a paucity of data on Latinas and prophylactic measures among BRCA1/2 carriers.Existing studies are limited either by the small number of Latinas, or limited to a specific geographic location.Factors related to decision making have also not been evaluated.
Methods: The UPTAKE study is an observational study of Latinas with germline BRCA1/2 mutations.Subjects were recruited nationally and, by telephone interviews, reported uptake of prophylactic surgeries (BSO, bilateral mastectomy in unaffected women, and contralateral mastectomy in carriers with breast cancer (BC)). Women with ovarian cancer were ineligible. All women had to have been informed that they carried a deleterious BRCA1/2 mutation at least 1 year prior to completing the interview. The objectives of this study are: 1)to examine the rate of uptake of prophylactic surgeries; 2)identify acculturation and attitudinal factors related to decisions made and 3)examine relationships between primary language, receipt of genetic counseling (GC) and in which language it was provided and uptake of prophylactic surgeries. We plan to enroll 100 participants.
Results: As of 6/11/2017, 86 telephone interviews have been conducted. We anticipate that all 100 interviews will be completed by July 2017. 51.2% (44/86) of participants completed the interview in Spanish. Our population was diverse in terms of country of origin: 50.0% (43/86) were born in the US, 22.1% (19/86) in Mexico, 11.6% (10/86) in Puerto Rico, 4.6% (4/86) in El Salvador, 3.5% (3/86) in Ecuador and 8.1% (7/86) in other countries of Latin America. 30% (26/86) of the participants reported an annual household income inferior to $50.000. Only 26.7% (23/86) of women reported having a graduate degree. Approximately one quarter of participants were unemployed at the time of study participation (26.7%, 23/86). 34.9% (30/86) were unaffected and 62.8% (54/86) were affected with BC. 73.3% (63/86) of participants reported having received formal GC, of which only 28.6% (18/63) was conducted in Spanish. 66.3% (57/86) of women opted to undergo BSO and 58.1% (50/86) underwent prophylactic mastectomy. Being born outside the US and currently working were associated with higher uptake of BSO. Multivariate analysis will be performed once all interviews have been completed.
Conclusions: To our knowledge this is the largest study that evaluates uptake of prophylactic measures in Latinas known to be BRCA1/2 carriers. Our study included a heterogeneous group of participants in terms of country of origin, income and level of education including English knowledge. It was conducted across various academic and community centers in the country. The uptake of prophylactic surgeries among Latinas with germline BRCA mutations seems to be slightly lower than what has been reported in non-Hispanic whites (71-74%) but higher than in African Americans (32-50%). Results and factors associated with decision making will be updated once the total number of participants is enrolled.

Abstract
The current study unveils the structural origin of the magnetic transition of the ε-Fe2O3 polymorph from an incommensurate magnetic order to a collinear ferrimagnetic state at low temperature. The high crystallinity of the samples and the absence of other iron oxide polymorphs have allowed us to carry out temperature-dependent x-ray absorption fine structure spectroscopy experiments out. The deformation of the structure is followed by the Debye-Waller factor for each selected Fe-O and Fe-Fe sub-shell. For nanoparticle sizes between 7 and 15 nm, the structural distortions between the Fete and Fe-D1oc sites are localized in a temperature range before the magnetic transition starts. On the contrary, the inherent interaction between the other sub-shells (named Fe-O1,2 and Fe-Fe1) provokes cooperative magneto-structural changes in the same temperature range. This means that the Fete with Fe-D1oc polyhedron interaction seems to be uncoupled with temperature dealing with these nanoparticle sizes wherein the structural distortions are likely moderate due to surface effects.

Abstract
Low concentrations of trace elements in many organic wastes recommend their supplementation in order to avoid potential limitations. Different chelating agents have been used to ensure an adequate trace metal pool in the soluble fraction, by forming dissolved complexes. Ethylenediaminetetraacetic acid (EDTA) is probably the most common, although several negative effects could be associated with its usage. Biomethane potential tests were performed using Olive Mill Solid Waste as the substrate, supplementing different combinations of Fe, Co, Ni, Ba, always under the presence of EDTA. Results show that Ni and Co slightly recovered biodegradability. However, Ba supplementation resulted in worsening the methane yield coefficient in all cases. High concentration of EDTA led to decrease in the activity of anaerobic digestion. High availability of EDTA induces the capture of trace metals like Co or Ni, key trace metals for anaerobic biomass activity. While supplementing trace metals, the addition of Ba and/or EDTA must be carefully considered.

Abstract
Native or pegylated (PEG) asparaginase (ASP) are commonly used in treatment of acute lymphoblastic leukemia (ALL), but have been scarcely compared in the same trial in adult patients. Native vs. PEG-ASP administered according to availability in each center were prospectively evaluated in adults with high-risk ALL. Ninety-one patients received native ASP and 35 PEG-ASP in induction. No significant differences were observed in complete remission, minimal residual disease levels after induction and after consolidation, disease-free survival, and overall survival. No significant differences in grades 3-4 toxicity were observed in the induction period, although a trend for higher hepatic toxicity was observed in patients receiving PEG-ASP. In this trial the type of ASP did not influence patient response and outcome.

Abstract
IgA anti-beta2-glycoprotein I (IgA-aB2GPI) antibodies are currently not included as a laboratory criterion of antiphospholipid syndrome (APS). In the 13th International Congress on Antiphospholipid Antibodies, Galveston, TX, (USA) in 2010, these antibodies were accepted as an APS laboratory criterion in patients who had clinical manifestations of APS but were negative for "consensus" antiphospholipid antibodies (aPL) (IgG and IgM isotypes). Consequently, individuals with thrombotic events who are negative for consensus aPL may be undiagnosed for APS. The most recent publications have confirmed that IgA-aB2GPI antibodies are a risk factor for thrombotic events. In this viewpoint, we propose that IgA-aB2GPI antibodies should be included as an APS consensus criterion and that we have to help Cinderella become a princess.

Abstract
PURPOSE Total skin electron irradiation (TSEI) is a radiotherapy technique which consists of an homogeneous body surface irradiation by electrons. This treatment requires very strict technical and dosimetric conditions, requiring the implementation of multiple controls. Recently, the Task Group 100 report of the AAPM has recommended adapting the quality assurance program of the facility to the risks of their processes. MATERIALS AND METHODS A multidisciplinary team evaluated the potential failure modes (FMs) of every process step, regardless of the management tools applied in the installation. For every FM, occurrence (O), severity (S) and detectability (D) by consensus was evaluated, which resulted in the risk priority number (RPN), which permitted the ranking of the FMs. Subsequently, all the management tools used, related to the TSEI process, were examined and the FMs were reevaluated, to analyze the effectiveness of these tools and to propose new management tools to cover the greater risk FMs. RESULTS 361 FMs were identified, 103 of which had RPN ≥80, initially, and 41 had S ≥ 8. Taking this into account the quality management tools FMs were reevaluated and only 30 FMs had RPN ≥80. The study of these 30 FMs emphasized that the FMs that involved greater risk were related to the diffuser screen placement and the patient's position during treatment. CONCLUSIONS The quality assurance program of the facility has been adapted to the risk of this treatment process, following the guidelines proposed by the TG-100. However, clinical experience continually reveals new FMs, so the need for periodic risk analysis is required.

Centralized management of sewage sludge and agro-industrial waste through co-composting. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2017; 196:387-393.

Abstract
In this research study, the co-composting process of a waste mixture containing strawberry extrudate, fish waste, sewage sludge and bulking agent (SEFW, 190:1:22:90 ratio) was carried out in a dynamic-solid respirometer at pilot scale. The aerobic biodegradability of the mixture was previously ensured in a static-liquid respirometer. The advantages and drawbacks of the SEFW co-composting process were subsequently identified through the determination of respirometric activity and the physical-chemical characterization of the waste, as well as the monitoring of odor emissions. The evolution of the physical-chemical variables showed that pH increased slightly and that the organic matter concentration, expressed as volatile solids (VS, %) or oxidable organic carbon (COXC, %), decreased by around 15% in both cases and by approximately 56% in its biodegradable form (total organic carbon, TOC, %). The low odor emission rate (OER) in the least favorable scenario (the maximum odor generation) during SEFW composting was 1.59 ouE/s, whereas this figure reached 3.52 ouE/s when only the organic fraction of municipal solid waste (OFMSW) was composted. Consequently, the co-composting of SEFW is more favorable in terms of odor emission and permits the simultaneous treatment of different types of waste.

Suitability of olive oil washing water as an electron donor in a feed batch operating bio-electrochemical system. GRASAS Y ACEITES 2017.

Abstract
Olive oil washing water derived from the two-phase manufacturing process was assessed as an electron donor in a bio-electrochemical system (BES) operating at 35 ºC. Start-up was carried out by using acetate as a substrate for the BES, reaching a potential of around +680 mV. After day 54, BES was fed with olive oil washing water. The degradation of olive oil washing water in the BES generated a maximum voltage potential of around +520 mV and a Chemical Oxygen Demand (COD) removal efficiency of 41%. However, subsequent loads produced a decrease in the COD removal, while current and power density diminished greatly. The deterioration of these parameters could be a consequence of the accumulation of recalcitrant or inhibitory compounds, such as phenols. These results demonstrated that the use of olive oil washing water as an electron donor in a BES is feasible, although it has to be further investigated in order to make it more suitable for a real application.

Abstract
Background: Alopecia is one of the secondary side effect whit the most emotionally impact for patients undergoing chemotherapy (CTX) The DigniCap System is the first scalp cooling system use to minimize alopecia. Methods: The objetive of this study was to evaluate in a restrospective trial the efficacy of DigniCap preventing alopecia in consecutive patients treated in ABC Medical Center from December 2010 to January 2015. Patients recieve different chemotherapy regimens, with different modalities, neo , adyuvant and for metastases in first and second line, as in many clinical stages whit breast cancer (BC), were evaluated with the visual scale of Dean (score 0: 0-25%, 1: 25-50%, 2: 50-75%, 3: 75-100%) with photographs of the before and after treatment. Results: 120 pts with BC in stages I-V were treated with a taxane and antraciclins regimen of chemotherapy, 66 pts receive 12 treatment weekly of paclitaxe (T)l and 4 adriamicin/cyclophosphamida (AC) every 21 days, 28 pts 6-8 cycles every 21 days AC-Taxol, 22 pts (18%)suspended the treatment because of the loss of more than 50% of hair at the 2nd an 3rd chemotherapy cycle. 98 pts actually finished the treatment (72%). Of these, 82 pts (84%) no had or had a minimal loss of hair (Dean score 0-1), 16 pts (16%) had a 50% of hair loss (Dean score 3). 8pts recieve more than one regimen of chemotherapy. In the tracing any metastases or side effects were presented with the use of DigniCap. Conclusions: The use of DigniCap minimize alopecia in a 84%, including pts with more than one chemotherapy regimen, in a a safety level.

Study of β 2-Glycoprotein I Polymorphisms in Patients With Chronic Renal Failure as a Predisposing Factor for the Development of Anti-β 2-Glycoprotein I Auto-Antibodies. Transplant Proc 2016; 48:2876-2879.

Abstract
BACKGROUND Immunoglobulin (Ig)A anti-β2-glycoprotein I (aB2GP1) antibodies are associated with thrombotic events, cardiovascular morbidity, and death in dialysis patients. About 30% of patients with chronic renal disease are positive for IgA aB2GP1; however, the origin of these antibodies is unknown. It has been speculated that dialysis membranes, age, or etiology of renal base disease are possible precipitating factors, although these factors do not appear to be the source of antibodies. B2GP1 is a protein of 326 amino acids grouped into five domains. Eight polymorphisms have been described; the most important are Val/Leu247, which appears to predispose aB2GP1 antibody production in patients with anti-phospholipid syndrome, and Trp/Ser316, which appears to have protective antibody production of aB2GP1. METHODS DNA samples from 92 patients with renal failure on hemodialysis were randomly collected with a 1:1 ratio for the positivity for IgA aB2GP1. Forty-six samples were positive for IgA aB2GP1 (group 1) and 46 negative for IgA aB2GP1 (group 2). All samples were anonymized to study polymorphism Val/Leu247 and polymorphism Trp/Ser316. RESULTS No significant differences were observed between those who were positive or negative for IgA aB2GP1 in patients with renal failure treated with hemodialysis and the polymorphism located in codons 247 and 316. CONCLUSIONS The two groups of patients have the same prevalence in polymorphisms 247 and 316, and therefore there appears not to be a genetic predisposition in our population. New trigger factors must be studied.
