Abstract
BACKGROUND This study explored the impact of Leucothyreus femoratus, a previously unreported folivorous pest in cacao cultivation, on cacao tree survival, development, and yield. The study was conducted in an experimental cacao plot in the Colombian plains, it featured 20 cacao genotypes in an agroforestry system, with plantain and Mexican sunflower providing temporary shade, and yopo offering permanent shade. RESULTS We found an infestation rate of 2.9 ± 0.3 adult beetles per cacao tree. L. femoratus larvae were discovered in association with the roots of all plants within the agroforestry arrangement; however, yopo and plantain exhibited the highest incidence of root-feeding larvae among these associated plants. Interestingly, male and female L. femoratus displayed distinct leaf consumption patterns in the laboratory, with females consuming more foliage relative to their body weight. Moreover, field observations highlighted the detrimental impact of L. femoratus herbivory on cacao tree survival and growth, leading to leaf skeletonization, reduced plant height, and stem diameter. Trees with over 50% leaf consumption suffered more than 20% mortality. Additionally, herbivory negatively affected cacao yield, correlating higher leaf surface damage with a decrease in harvested pods. The study also identified varying antixenotic resistance in different cacao genotypes, with some consistently displaying resistance while others showed variable levels during tree establishment and production stages. CONCLUSION This research underscores the significant role of L. femoratus as a cacao pest, emphasizing its adverse effects on cacao tree survival, development, and yield. Consequently, implementing effective control measures is vital for ensuring sustainable cacao cultivation. © 2023 Society of Chemical Industry.

Abstract
Iberian lacustrine sediments are a valuable archive to document environmental changes since the last glacial termination, seen as key for anticipating future climate/environmental changes and their far-reaching implications for generations to come. Herein, multi-proxy-based indicators of a mountain lake record from Serra da Estrela were used to reconstruct atmospheric (in)fluxes and associated climatic/environmental changes over the last ∼13.5 ka. Depositions of long-range transported dust (likely from the Sahara) and halogens (primarily derived from seawater) were higher for the pre-Holocene, particularly in the late Bølling-Allerød-Younger Dryas period, compared to the Holocene. This synchronous increase could be related to a recognized dust-laden atmosphere, along with the combined effect of (i) an earlier proposed effective transport of Sahara dust for higher latitudes during cold periods and (ii) the progressive Polar Front expansion southwards, with the amplification of halogen activation reactions in lower latitudes due to greater closeness to snow/sea ice (halide-laden) surfaces. Additionally, the orographic blocking of Serra da Estrela may have played a critical role in increasing precipitation of Atlantic origin at higher altitudes, with the presence of snow prompting physical and chemical processes involving halogen species. In the Late Holocene, the dust proxy records highlighted two periods of enhanced input to Lake Peixão, the first (∼3.5-2.7 ka BP) after the end of the last African Humid Period and the second, from the 19th century onwards, agreeing with the advent of commercial agriculture, and human contribution to land degradation and dust emission in the Sahara/Sahel region. The oceanic imprints throughout the Holocene matched well with North Atlantic rapid climatic changes that, in turn, coincided with ice-rafted debris or Bond events and other records of increased storminess for the European coasts. Positive parallel peaks in halogens were found in recent times, probably connected to fire extinction by halogenated alkanes and roadway de-icing.

Abstract
PURPOSE To evaluate if nonlinear supervised learning classifiers based on non-contrast CT can predict functional prognosis at discharge in patients with spontaneous intracerebral hematoma. METHODS Retrospective, single-center, observational analysis of patients with a diagnosis of spontaneous intracerebral hematoma confirmed by non-contrast CT between January 2016 and April 2018. Patients with HIE > 18 years and with TCCSC performed within the first 24 h of symptom onset were included. Patients with secondary spontaneous intracerebral hematoma and in whom radiomic variables were not available were excluded. Clinical, demographic and admission variables were collected. Patients were classified according to the Modified Rankin Scale (mRS) at discharge into good (mRS 0-2) and poor prognosis (mRS 3-6). After manual segmentation of each spontaneous intracerebral hematoma, the radiomics variables were obtained. The sample was divided into a training and testing cohort and a validation cohort (70-30% respectively). Different methods of variable selection and dimensionality reduction were used, and different algorithms were used for model construction. Stratified 10-fold cross-validation were performed on the training and testing cohort and the mean area under the curve (AUC) were calculated. Once the models were trained, the sensitivity of each was calculated to predict functional prognosis at discharge in the validation cohort. RESULTS 105 patients with spontaneous intracerebral hematoma were analyzed. 105 radiomic variables were evaluated for each patient. P-SVM, KNN-E and RF-10 algorithms, in combination with the ANOVA variable selection method, were the best performing classifiers in the training and testing cohort (AUC 0.798, 0.752 and 0.742 respectively). The predictions of these models, in the validation cohort, had a sensitivity of 0.897 (0.778-1;95%CI), with a false-negative rate of 0% for predicting poor functional prognosis at discharge. CONCLUSION The use of radiomics-based nonlinear supervised learning classifiers are a promising diagnostic tool for predicting functional outcome at discharge in HIE patients, with a low false negative rate, although larger and balanced samples are still needed to develop and improve their performance.

Abstract
Viewing the Substance Abuse and Mental Health Services Administration's recovery principles through an antiracist lens has guided the authors' vision of recovery-oriented systems for all. In this brief letter, they present some considerations arising from their application of recovery principles to areas affected by racial bias. They are also identifying best practices for incorporating micro and macro antiracism efforts into recovery-oriented health care. These are important steps in promoting recovery-oriented care, but there is much more to do. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
INTRODUCTION Obstructive sleep apnea (OSA) has been proposed as a factor that worsens stroke prognosis. Our aim was to determine if an OSA intervention could improve quality of life (QOL, first objective) and modified Rankin score (mRS, second objective). PATIENTS AND METHODS The intervention group of this quasi-experimental study included patients with acute ischemic stroke <72 hours who underwent polygraphy and Continuous Positive Airway Pressure (CPAP) and hygienic-dietary measures if required. The control group followed routine clinical practice. The Short Form 36 Health Survey (SF-36) and mRS were applied at the sixth month after stroke in both groups. RESULTS Fifty-five vs. sixty-two patients were included in the intervention and control group respectively. In the intervention group, 64.71% of patients accepted the proposed CPAP (16 cases with a good adherence). An improvement in SF-36 items was detected in the intervention group: physical functioning (p = 0.008), role physical (p = 0.002), bodily pain (p = 0.008), general health (p <0.001), vitality (p = 0.001) and role emotional (p = 0.015). In a per-protocol analysis, all these improvements were verified in the group of patients treated with good CPAP adherence (p < 0.05 in all the same SF-36 items). The percentage of patients with physical component summatory = 50 was higher in the intervention group (p = 0.003). There were no differences in the median of mRS (p = 0.262). CONCLUSIONS Although more evidence is needed, a significant improvement in QOL was suggested after our OSA intervention, particularly in patients with good CPAP adherence.

Abstract
Abstract
Background
In the United States, booster vaccines for persons 18 years and older were approved under Emergency Use Authorization (EUA) in September 2021. Waning immunity following SARS-CoV-2 primary vaccination series led to recommendations for booster vaccination. Emerging data suggest that providing boosters different from the primary series (heterologous vaccination) may provide a broader immune response than boosting with the same vaccine (homologous vaccination). CDC recommended the Pfizer-BioNTech BNT162b2 30-μg mRNA booster vaccine to clinical trial participants >6 months post study vaccines if not planned for boosting within the study.
Methods
We conducted an observational study of persons who received 2 doses of Novavax protein-based NVX-CoV2373 vaccine 21 days apart, in a Phase 3 clinical trial, and subsequently received a Pfizer BNT162b2 booster vaccine under EUA. Serologic assays, including the Roche anti-nucleocapsid (N) IgG and anti-Spike (S) IgG, were performed on blood collected pre-booster (D0) and on days 18 (D18) and 34 (D34) post-booster vaccine. The anti-S IgG geometric means (GMTs) were calculated over study time points. Wilcoxon signed rank test was performed to compare anti-S IgG response between D0 and D18 and D0 and D34.
Results
Of 26 participants enrolled, 16 (57%) were women; the median age was 47 years (range 29-67). Roche anti-N antibodies were negative at all visits. Time from second NVX-CoV2373 vaccine to Pfizer BNT162b2 booster was a median of 10.4 months in 54% of participants and 7 months in 46% of participants. Anti-S IgG GMTs were 222 BAU/ml D0, 24,723 BAU/ml D18, and 24,584 BAU/ml D34 (p< 0.0001 for comparisons of D0 with D18 & D34). Overall, participants tolerated the booster vaccine without significant adverse events. Cell mediated immunity and D614G pseudovirus neutralizing antibody assays are in progress. Figure 1.Anti-S IgG titers pre and post-booster vaccine
16 participants included with all 3-time study time points for comparison.
Conclusion
Two doses of NVX-CoV2373 vaccine followed by the Pfizer BNT162b2 booster vaccine resulted in ∼100-fold increase in anti-S IgG against SARS-CoV-2. No participant had evidence of prior SARS-CoV-2 infection by anti-N IgG. Two doses of NVX-CoV2373 vaccine followed by one dose of Pfizer BNT162b2 vaccine is an effective and well-tolerated regimen for boosting anti-S IgG against SARS-CoV-2.

Background
Ablation of drivers in persistent atrial fibrillation (AF) has shown controversial results [1-5].
Purpose
To test the efficacy of a tailored approach for persistent AF ablation which includes pulmonary vein isolation (PVI) plus ‘subjective’ identification and ablation of drivers.
Methods
From May 2017, selected patients with persistent AF and ongoing AF at the beginning of the ablation procedure were included. Conventional high-density mapping catheters were used. Drivers were subjectively identified as: a) fractionated continuous (or quasi-continuous) electrograms on 1-2 adjacent bipoles, without dedicated software (Figure, A, dashed line; PR = PentaRay NAV); and b) sites with spatiotemporal dispersion (i.e. all the cycle length comprised within the mapping catheter) plus non-continuous fractionation on single bipoles (Figure, B, arrows; in panels A and B: paper speed 200 mm/s; ORB = 24-pole ORBITER Woven catheter, blue bipoles around tricuspid annulus and green bipoles into the coronary sinus). Ablation included PVI + focal or linear ablation targeting sites with drivers. Ablation success was defined as conversion to sinus rhythm or atrial flutter during ablation. Follow-up included visits with 24h Holter ECG at 3-6-12 months. The primary endpoint was one-year survival free from atrial arrhythmias lasting >30 seconds. We present the results of the first 50 patients included, comparing them with all consecutive patients with persistent AF treated with a PVI-only strategy.
Results
173 Patients received ablation: 50 with the tailored approach (61,2±9,6 years; 24% females) and 123 with only PVI (62,5±9,6 years; 25% females; 89% cryoablation). Basal characteristics were similar (Table), but more patients with long-standing persistent AF were ablated witth the tailored-approach group. In the tailored-approach group, 21 patients (42%) presented 40 detectable sites with continuous fractionated electrograms, 38 on the left atrium and 2 on the right atrium, which was only mapped if ablation of drivers in the left atrium was not successful; 18 (45%) were located within the pulmonary vein antra. 41 patients (82%) showed 143 sites with spatiotemporal dispersion (4 [3 – 4] per patient). Ablation success was achieved in 21 patients (42%; conversion to sinus rhythm, n=7; conversion to atrial flutter, n=14) in the tailored-approach group and 1 patient (0,8%, sinus rhythm) in the PVI-only group. Excluding a 3-month blanking period, the tailored approach, compared to only PVI, improved one-year freedom from atrial arrhythmias (70% Vs 52%, p=0,032) (Figure, C), at the cost of a longer median procedural time (244 [187–275] Vs 108 [81–143] min, p<0,001) and fluoroscopy time (41 [28–65] Vs 33 [21–45] min, p<0,001).
Conclusion
Subjective identification and ablation of drivers, added to PVI, improved one-year survival free from atrial arrhythmias.

Anomalous intracranial vessels are not uncommon, and this finding is not always associated with arteriovenous malformations. Other conditions such as anomalous connections between arteries or phlebitc patterns can also present as vessels with abnormal intracranial locations. Noninvasive diagnosis is important to determine whether to do more invasive tests such as cerebral digital subtraction angiography or to estimate the risk of bleeding in arteriovenous malformations and therefore to evaluate the need for endovascular/surgical treatment. In this paper, we present an algorithm for the differential diagnosis of anomalous intracranial vessels according to their location (intra/extra-axial) and function (whether the vessels are arterialized). Moreover, we analyze the important points of the angioarchitecture of the principal arteriovenous malformations with risk of intracranial bleeding, such as pial arteriovenous malformations and dural fistulas.

Abstract
Abstract
Background
Ablation of drivers in persistent atrial fibrillation (AF) has shown controversial results.
Purpose
To test the efficacy of a tailored approach for persistent AF ablation which includes pulmonary vein isolation (PVI) plus “subjective” identification and ablation of drivers.
Methods
From May 2017 to December 2019, selected patients with persistent AF and ongoing AF at the beginning of the ablation procedure were included. Conventional high-density mapping catheters (PentaRay NAV, IntellaMap Orion or Advisor HD Grid) were used. Drivers were subjectively identified as: a) fractionated continuous (or quasi-continuous) electrograms on 1–2 adjacent bipoles, without dedicated software (Figure 1A, dashed line; PR = PentaRay NAV); and b) sites with spatiotemporal dispersion (i.e. all the cycle length comprised within the mapping catheter) plus non-continuous fractionation on single bipoles (Figure 1B, arrows; in panels A and B: paper speed 200 mm/s; ORB = 24-pole ORBITER Woven catheter, blue bipoles around tricuspid annulus and green bipoles into the coronary sinus). Ablation included PVI + focal or linear ablation targeting sites with drivers. Ablation success was defined as conversion to sinus rhythm or atrial flutter during ablation. Follow-up included visits with 24h Holter ECG at 3–6–12 months. Survival free from atrial arrhythmias lasting >30 seconds was compared between patients ablated with this tailored approach, and all consecutive patients with persistent AF treated with a PVI-only strategy during the same period.
Results
158 Patients received ablation: 35 with the tailored approach (61,7±10,2 years; 29% females) and 123 with only PVI (62,5±9,6 years; 25% females; 89% cryoablation). Basal characteristics were similar (Table 1). In the tailored-approach group, 14 patients (40%) presented 28 detectable sites with continuous fractionated electrograms, 26 on the left atrium and 2 on the right atrium, which was only mapped if ablation of drivers in the left atrium was not successful; 12 (43%) were located within the pulmonary vein antra. 27 patients (77%) showed 103 sites with spatiotemporal dispersion (4 [3–5] per patient). Ablation success was achieved in 17 patients (48%; conversion to sinus rhythm, n=7; conversion to atrial flutter, n=10) in the tailored-approach group and 1 patient (0,8%, sinus rhythm) in the PVI-only group. Excluding a 3-month blanking period, the tailored approach, compared to only PVI, improved one-year freedom from atrial arrhythmias (71% Vs 51%, p=0,05) and mean survival free from atrial arrhythmias (26±3 months; 95% CI 21–32 months Vs 18±2 months; 95% CI 15–22 months) (Figure 1C), at the cost of a longer median procedural time (246 [212–277] vs 108 [81–143] min, p<0,001) and fluoroscopy time (51 [36–76] vs 33 [21–45] min, p<0,001).
Conclusion
Subjective identification and ablation of drivers, added to PVI, improved freedom from atrial arrhythmias.

Abstract
Composting has been traditionally considered a process in which a succession of mesophilic and thermophilic microbial populations occurs due to temperature changes. In order to deepen in this model, 1380 bacterial and fungal strains (the entire culturable microbiota isolated from a composting process) were investigated for their ability to grow across a wide range of temperatures (20 to 60 °C). First, qualitative tests were performed to establish a thermal profile for each strain. Then, quantitative tests allowed ascertaining the extent of growth for each strain at each of the tested temperatures. The identity of the isolates enabled to position them taxonomically and permitted tracking the strains throughout the process. Results showed that 90% of the isolates were classified as thermotolerant (they grew at all tested temperatures). Only 9% and 1% of the studied strains showed to be strictly mesophilic or thermophilic, respectively. Firmicutes exhibited the greatest thermal plasticity, followed by Actinobacteria and Ascomycota. Most of the Proteobacteria and all Basidiomycota strains were also able to grow at all the assayed temperatures. Thermotolerance was clearly demonstrated among the composting microbiota, suggesting that the idea of the succession of mesophilic and thermophilic populations throughout the process might need a reassessment.

Abstract
Background:The most common complication in patients with SLE is infection, and its clinical presentation is often indistinguishable from SLE flares. Therefore, laboratory ratios have been evaluated to differentiate between those events. Among them, ESR/CRP1, neutrophil/lymphocyte (NLR)2, and platelet/lymphocyte (PLR)3 ratios have been previously assessed with acceptable performance; however, there is no validation of those ratios in our SLE population.Objectives:To examine the predictive capacity of infection of the lymphocyte/C4 (LC4R), lymphocyte/C3 (LC3R), and ferritin/ESR (FER) ratios in SLE patients, and to evaluate the performance of ESR/CRP, NLR, AND PLR ratios in our SLE population.Methods:We conducted a cross-sectional study of SLE patients admitted to the emergency service at Hospital San Vicente Fundación (HSVF). The HSVF ethics committee approved the execution of the project.Patients were categorized into four groups according to the main cause of hospitalization: (1) infection, (2) flare, (3) infection and flare and, (4) neither infection nor flare.We calculated the median values of the ratios and their respective interquartile ranges for each group. Then, we compared those summary measures using the Kruskal-Wallis test. Subsequently, we assessed the predictive capacity of infection of each ratio using ROC curve. Finally, we carried out a logistic regression model.Results:A total of 246 patients were included, among them 90.7% were women. The median age was 28 years (IQR: 20-35 years). Regarding the outcomes, 37.0% of the patients had flares, 30.9% had neither infection nor flare, 16.7% had an infection and, 15.5% had simultaneously infection and flare. When compared the four groups, statistical significance (p<0.05) was observed. Area under the ROC curve (AUC) for infection prediction was as follows: 0.752 (sensitivity 60.5%, specificity 80.5%) for LC4R, 0.740 (sensitivity 73.2%, specificity 68.3%) for FER, 0.731 (sensitivity 77.6%, specificity 80.5%) for LC3R.In the logistic regression modeling, we observed that an increase in the risk of infection was associated with an LC4R below 66.7 (OR: 6.3, CI: 2.7 – 14.3, p <0.0001), a FER greater than 13.6 (OR: 5.9, CI: 2.8 – 12.1, p <0.0001) and an LC3R below 11.2 (OR: 4.9, CI: 2.4 – 9.8, p <0.0001).The ESR/CRP and PLR performed poorly with an AUC of 0.580 and 0.655, respectively. In contrast, the NLR showed better performance (AUC of 0.709, with a sensitivity of 80.2% and specificity of 55.7%).Figure 1.ROC curves of the evaluated ratiosConclusion:These laboratory ratios could be easy to assay and inexpensive biomarkers to differentiate between infection and activity in SLE patients. The LC4R, FER, and LC3R have a significant diagnostic performance for detecting infection among SLE patients. Of the ratios previously evaluated, ESR/CRP, LPR, NLR, only the latest has an adequate performance in our population.References:[1]Littlejohn E, Marder W, Lewis E, et al.

Background. Unstable reentrant atrial tachycardias (ATs) (i.e. those with frequent circuit modification or conversion to atrial fibrillation) are challenging to ablate.
Purpose. We have tested a strategy to convert unstable reentrant ATs into mappable stable ATs based on the detection and ablation of rotors.
Methods. From May 2017 to December 2019, we included all consecutive patients scheduled for ablation of reentrant AT, excluding CTI-dependent atrial flutter, in which the tachycardia circuit was unstable. Operators subjectively identified rotors as sites with fractionated continuous (or quasi-continuous) electrical signals on 1-2 adjacent bipoles of conventional high-density mapping catheters, without dedicated software (Figure, A). Focal ablation of these sites was performed in order to stabilize the AT or convert it into sinus rhythm. In patients without rotors or failed rotor ablation, sites with spatiotemporal dispersion (i.e. all the cycle length comprised within the mapping catheter) plus non-continuous fractionation on single bipoles were targeted (Figure, B). Procedural success was defined as the successful ablation of all inducible ATs, without need of cardioversion, final sinus rhythm and non-inducibility. Follow-up included visits with ECG and 24h Holter-ECG at 3, 6 and 12 months.
Results. From May 2017 to December 2019, 97 patients were scheduled for reentrant AT ablation, excluding CTI-dependent atrial flutter. Of these, 18 patients (18.6%; 72.1 ± 8.9 years of age, 9 females) presented unstable circuits and were included. 9 patients (50%) had structural cardiomyopathy, 11 patients (61%) prior atrial arrhythmias ablations, and 4 patients (22%) previous cardiac surgery. 13 patients (72%) had detectable rotors (26 rotors; median 2 [1–3] rotors per patient); focal ablation achieved conversion into stable AT or sinus rhythm in 12 (92%). In the other patient, and the 5 patients without detectable rotors, 17 sites with spatiotemporal dispersion were detected and focally ablated, with success to achieve arrhythmia stabilization in 5 patients (83%). Globally, and excluding one patient with spontaneous AT stabilization, ablation success to stabilize the AT was achieved in 16/17 patients (94.1%). Procedural success was achieved in 16/18 patients (88.9%). Rate of one-year freedom from atrial arrhythmias was 66.7%. In the 9 patients with stable ATs ablated during the same period, procedural success (92.4%) and one-year freedom from atrial arrhythmias (65.8%) were similar (Figure, C).
Conclusion. Most unstable reentrant ATs show detectable rotors, identified as sites with single-bipole fractionated quasi-continuous signals, or spatiotemporal dispersion plus non-continuous fractionation. Ablation of these sites is highly effective to stabilize the AT or convert it into sinus rhythm. Abstract FIGURE

Introduction
Catheter navigation and 3-dimensional (3D) cardiac mapping are critical for successful electrophysiological ablation procedures. A novel 3D mapping system received CE Mark in July 2020. The system offers two imaging modalities: magnetic-based (VoXel) and impedance-based (NavX). Real-time display of 3D location and catheter movements is achieved via a magnetic field frame and magnetic sensors with supplemental impedance data when operating in VoXel mode or primarily via an impedance field generated from surface electrodes in NavX mode. To address limitations in data collection commonly experienced during 3D mapping, a new respiratory compensation algorithm, patient movement detection module, and metal compensation algorithm have been developed to enable consistent data collection throughout the full respiratory cycle even in challenging cases and lab environments.
Purpose
To examine the clinical utility and procedural characteristics associated with the use of this novel 3D mapping system among participating centers.
Methods
Procedural data was collected in cases utilizing the newly cleared mapping system during the initial evaluation phase in Europe. Procedural characteristics recorded included indication for mapping and ablation, rhythm mapped, chambers mapped, and procedure time.
Results
Procedural data was collected from over 250 cases across 12 European centers. A total of 12 indications for mapping and ablation were represented including de novo and redo atrial fibrillation (paroxysmal, persistent, long-standing persistent), ventricular tachycardia (ischemic, non-ischemic) or premature ventricular contraction, and supraventricular arrhythmias (typical and atypical atrial flutter, atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia). Over 70% of the cases were performed in VoXel mode. Impedance mode was mostly used in SVT cases or when the case was intended to be completed with minimal fluoroscopy. The most commonly mapped rhythms were sinus rhythm during voltage mapping and atrial tachycardia. The majority of cases (over 65%) were completed under conscious sedation; general anesthesia was used in 20% of the cases (15% not reported). The respiratory compensation algorithm was utilized in over 90% of the cases. For cases in which pre-procedural computed tomography or magnetic resonance imaging were available, operators indicated that the model shape was accurate when compared to pre-procedural imaging in 96% of the cases performed in VoXel mode.
Conclusions
Initial European experience with this novel 3D mapping system included a wide variety of arrhythmias in the atria and ventricles. This new mapping system offered operators the flexibility to tailor to specific procedure needs with two imaging modalities which were both widely utilized.

Abstract
This work highlights the ability of various cyanobacterial extracts from Anabaena spp., Tolypothrix spp., Nostoc or Trichormus, among others genera, to control the incidence of damping-off caused by Pythium ultimum in cucumber seedlings. Protocols applied aimed at the preliminary characterization of the cyanobacterial collection were very useful for predicting their phytotoxic, phytostimulating and biopesticidal capacity. First, the phytostimulatory or phytotoxic potential of a collection of 31 sonicated cyanobacterial extracts was analyzed by calculating the germination index in watercress seeds and the increase or loss of seedling weight. Likewise, the collection was characterized according to its ability to inhibit the growth of P. ultimum by dual culture bioassays and detached-leaf test. Finally, after selecting the most effective extracts, a preventive damping-off bioassay was performed based on cucumber seed biopriming. The strain SAB-M465 showed to be the most efficient strain against the in vitro growth of P. ultimum, while SAB-B912 was more discreet in this regard, but proved to be the most effective as a germination stimulator. Seed biopriming strategy with sonicated extracts of cyanobacteria revealed a remarkable promoter effect in the early stages of plant development, although only SAB-M465 was positioned as an effective control agent against damping-off caused by P. ultimum in cucumber seedbeds.

Abstract
The ERAS guidelines are intended to identify, disseminate and promote the implementation of the best, scientific evidence-based actions to decrease variability in clinical practice. The implementation of these practices in the global clinical process will promote better outcomes and the shortening of hospital and critical care unit stays, thereby resulting in a reduction in costs and in greater efficiency. After completing a systematic review at each of the points of the perioperative process in cardiac surgery, recommendations have been developed based on the best scientific evidence currently available with the consensus of the scientific societies involved.

Abstract
RATIONALE Compulsive behaviour, present in different psychiatric disorders such as obsessive-compulsive disorder, schizophrenia and drug abuse, is associated with altered levels of serotonin (5-hydroxytryptamine, 5-HT). The gut microbiota regulates tryptophan (TRP) metabolism and may affect global 5-H synthesis in the enteric and central nervous systems, suggesting a possible involvement of gut microbiota in compulsive spectrum disorders. OBJECTIVES The present study investigated whether chronic TRP depletion by diet alters the faecal bacterial community profiles of compulsive versus non-compulsive rats in schedule-induced polydipsia (SIP). Peripheral plasma 5-HT and brain-derived neurotrophic factor (BDNF) levels were evaluated. METHODS Wistar rats were selected as High Drinkers (HD) or Low Drinkers (LD) according to their SIP behaviour and were fed for 14 days with either a TRP-free diet (T-) or a TRP-supplemented diet (T+). The faecal bacterial community structure was investigated with 16S rRNA gene-targeted denaturing gradient gel electrophoresis (DGGE) fingerprinting analysis. RESULTS Compulsive HD rats showed a lower bacterial diversity than LD rats, irrespectively of the diet. The TRP-depleted HD rats, the only group increasing compulsive licking in SIP, showed a reduction of bacterial evenness and a highly functionally organized community compared with the other groups, indicating that this bacterial community is more fragile to external changes due to the dominance of a low number of species. The chronic TRP depletion by diet effectively reduced peripheral plasma 5-HT levels in both HD and LD rats, while plasma BDNF levels were not altered. CONCLUSIONS These results highlight the possible implication of reduced microbial diversity in compulsive behaviour and the involvement of the serotonergic system in modulating the gut brain-axis in compulsive spectrum disorders.

Abstract
Identifying an optimal composition of nonoperative therapies to trial in patients suffering from degenerative lumbar spine conditions prior to surgical management remains challenging. Contrasting successful versus failed nonoperative treatment approaches may provide clinicians with valuable insight. The purpose of this study was to compare the nonoperative therapy regimens in degenerative lumbar spine disorder patients successfully managed conservatively versus patients who failed primary treatment and opted for lumbar fusion surgery. Clinical records from patients diagnosed with lumbar stenosis or spondylolisthesis from 2007 to 2017 were gathered from a comprehensive insurance database. Patients were separated into two cohorts: patients managed successfully with nonoperative therapies and patients who failed conservative therapy and underwent lumbar fusion surgery. Nonoperative therapy utilization by the two cohortswere collected across a 2-year surveillance window. A total of 531,980 adult patients with lumbar stenosis or spondylolisthesis comprised the base population. There were 523,031 patients (98.3%) successfully treated with conservative management alone, while 8,949 patients (1.7%) ultimately failed nonoperative management and opted for lumbar fusion.Conservative therapy failure rates were especially high in patients with a smoking history (2.1%) and those utilizing lumbar epidural steroid injections (LESIs) (3.7%). A greater percentage of patients who failed conservative management utilized opioid medications (p < 0.0001), muscle relaxants (p < 0.0001), and LESIs (p < 0.0001). Patients who failed nonoperative management spent more than double than the successfully treated cohort (failed cohort: $1806.49 per patient; successful cohort: $768.50 per patient). In a multivariate logistic regression model, smoking, obesity and prolonged opioid use were independently associated with failure of nonoperative treatment.

Abstract
During the last two decades, the method most widely used to manage olive mill wastewater (OMW) derived from olive oil production has been its disposal in evaporation ponds. Long-term storage of OMW leads to the accumulation of toxic sediments (OMWS) rich in recalcitrant compounds with phytotoxic and antimicrobial properties, which limit their use for agronomic purpose. The aim of this study was to compare the effect of two in situ bioremediation strategies (composting and a combination of composting followed by vermicomposting) to remove the potential toxicity of the sediments derived from long-term stored OMW. The results obtained showed that the composting method assisted with the earthworms enhanced the depletion of phenolic compounds and OMWS ecotoxicity more than composting, especially during the maturation stage. Moreover, vermicomposting was more effective in the reduction of the OMWS salinity. However, a pre-composting process to the OMWS is necessary prior to vermicomposting to provide the suitable conditions for earthworms survival and activity. Furthermore, the final compost showed a phytostimulating effect. Therefore, these in situ bioremediation strategies can be considered potential tools for decontamination and recovery of long-term stored OMWS in evaporation ponds, which currently poses an unsolved environmental problem.

Abstract
BACKGROUND Pulmonary artery hypertension (PAH) is a complex disorder that can lead to right heart failure. The generation of caveolin-1 deficient mice (CAV-1-/-) has provided an alternative genetic model to study the mechanisms of pulmonary hypertension. However, the vascular adaptations in these mice have not been characterized. OBJECTIVE To determine the histological and functional changes in the pulmonary and carotid arteries in CAV-1-/- induced PAH. METHODS Pulmonary and carotid arteries of young (4-6 months old) and mature (9-12 months old) CAV-1-/- mice were tested and compared to normal wild type mice. RESULTS Artery stiffness increases in CAV-1-/- mice, especially the circumferential stiffness of the pulmonary arteries. Increases in stiffness were quantified by a decrease in circumferential stretch and transition strain, increases in elastic moduli, and an increase in total strain energy at physiologic strains. Changes in mechanical properties for the pulmonary artery correlated with increased collagen content while carotid artery mechanical properties correlated with decreased elastin content. CONCLUSIONS We demonstrated that an increase in artery stiffness is associated with CAV-1 deficiency-induced pulmonary hypertension. These results improve our understanding of artery remodeling in PAH.

Abstract
Abstract
Background
Atypical atrial flutter (AAFL) circuits use areas of slow conduction which can be visualized as fragmented electrograms (fEGMs).
Purpose
To test an ablation strategy based on the identification and ablation of spots with fEGMs in AAFL.
Methods
The MAP-FLURHY study prospectively included all AAFL ablations with Rhythmia in our Center from June 2016 to June 2019. Patients with non-mappable AAFL, frequent conversion to atrial fibrillation, or cavotricuspid isthmus-dependent flutters were excluded from analysis. The IntellaMap ORION catheter was used to detect fragmentation areas, arbitrarily defined as fEGMs >70ms. Entrainment was used to check if these areas belonged to the AAFL circuit. Ablation targeted the longest fEGM within the circuit (return cycle <30ms): focal ablation for microreentries, and lines including the fEGMs for macroreentries. Ablation success was defined as conversion to sinus rhythm or another flutter. Procedural success was defined as successful ablation of all inducible flutters. Follow-up included visits with 24h Holter ECG at 3–6-12 months.
Results
50 Patients received ablation (Figure). 27 Patients (70.6±13.1 years; 10 females; LVEF 57%±13%) with 44 mappable AAFLs were included in the analysis (Table). All AAFLs showed areas with fEGMs (106 areas; 2.4 areas per flutter). 42/44 AAFLs had fEGMs within the circuit, which were target of ablation. Ablation success: 34/36 AAFLs (94%); success could not be assessed in 6 circuits, due to mechanical conversion to sinus rhythm onto the target fEGM. Fragmented areas within the AAFL circuits (n=51) were longer (110±30 vs 90±15 ms, p<0.001) but had similar voltage (0.34±0.25 vs 0.36±0.26 mV) than areas outside the circuits (n=45). A fEGM duration >100ms/>40% of the cycle length predicted to be a successful site for ablation with 72.3%/73.8% specificity. Procedural success was achieved in 24/27 patients (89%). Excluding a 2-month blanking period, mean survival free from atrial arrhythmias was 19 (95% CI: 12.6–25.5) months. 57% of the patients were free from atrial arrhythmias at 1 year.
Conclusions
Most AAFLs had detectable fEGMs which could be target of ablation with high efficacy.

Abstract
Currently, the metagenomic study of the composting process has gained great importance since it has allowed the identification of the existence of microorganisms that, until now, had not been isolated during the process by traditional techniques. However, it is still complex to determine which bioindicators could reveal the degree of maturity and stability of a particular compost. Thereby, the main objective of this work was to demonstrate the possible correlation between traditional parameters of maturity and stability of compost, with other indicators of biodiversity in products highly heterogeneous from composting processes on an industrial scale. The results demonstrated the enormous influence of the raw materials in characterizing the products obtained. Even so, important relationships were established between the Chao1 and Shannon indexes, and certain parameters related to the maturity, stability and toxicity of the samples, such as nitrification index, humification rate, phenolic content, germination index or oxygen consumption.

Abstract
Bromine (Br) cycling in natural wetlands is highly complex, including abiotic/biotic processes and multiphase inorganic/organic Br-species. Wetland ecosystems receive Br primarily from the ocean, functioning as either sinks or sources of Br, with the overall imbalance largely decided by the prevailing climate. Aiming to trace the present-day transport of oceanogenic Br (i.e., derived from salt-water spray-droplets) and its uptake and storage in brackish and freshwater wetlands, we surveyed waters, autochthonous plants, and soils/sediments from coastal marshes and mountain peatlands in the westernmost fringe of northern Portugal. The calculated enrichment factors of bromide (Br-) relative to chloride in rainfall (EFsea = 16.8-75.3), rivers (EFsea = 1.3-13.9) and wetland waters, superficial (EFsea = 5.8-13.1) and interstitial (EFsea = 2.1-8.9), increased towards the inland highlands. We hypothesized that these values derived mostly from a known Br autocatalytic (heterogeneous) chemical cycle, starting at the seawater-aqueous interface and progressing in altitude. Br-bearing air masses are carried far from the Atlantic Ocean by moist westerlies, with Br- rainout from the atmosphere supplying the neighbouring mountain peatlands. Average [Br] in sampled wetland soils/sediments (111-253 mg/kg) agreed with values from other coastal regions, and they were directly correlated with the abundance of organic matter, varying irrespective the [Br-] of interstitial waters (129 μg/L-79 mg/L). According to the computed bioconcentration factors, the aqueous component was the major source of Br for all plant species investigated (BFplant/water = 2.1-508.0), as described elsewhere. However, Br contents in plants (14-173 mg/kg) evidenced interspecific differences, also suggesting a divergence from the acknowledged halophytic-glycophytic "model". As plants are recognized producers of Br volatile molecules (e.g., methyl bromide, CH3Br), we interpreted translocation factors less than one in vascular species as explanatory of phytovolatilization rather than restriction of Br- upward movement in plants. Further investigation is needed, since considerable intrinsic plant variations in CH3Br emissions are mentioned in the literature.

Abstract
Prior to anterior cervical discectomy and fusion (ACDF) surgery, patients suffering from cervical stenosis traditionally trial non-operative treatments for pain management. There is a paucity of data evaluating gender disparities in the prolonged utilization of conservative therapy prior to ACDF surgery. Therefore, the purpose of this study was to assess for gender-based differences in the utilization and cost of maximal non-operative therapy (MNT) for cervical stenosis prior to ACDF surgery. Medical records from patients with symptomatic cervical stenosis undergoing 1, 2, or 3-level index ACDF procedures between 2007 and 2016 were gathered from an insurance database consisting of 20.9 million covered lives. The utilization of MNTs within 5 years prior to index ACDF surgery was assessed. A total of 2254 patients (females: 53.1%) underwent an index ACDF surgery. There were a significantly greater percentage of female patients that utilized NSAIDs (p < 0.0001), opioids (p = 0.0019), muscle relaxants (p < 0.0001), cervical epidural steroid injections (p = 0.0428), and physical therapy/occupational therapy treatments (p < 0.0001). The total direct cost associated with all MNT prior to index ACDF was $4,833,384. On average, $2028.01 was spent per male patient while $2247.29 was spent per female patient. When normalized by number of pills billed per patient utilizing therapy, female patients utilized more NSAIDs (males: 591.8 pills, females: 669.3 pills), opioids (male: 1342.0 pills, female: 1650.1 pills), and muscle relaxants (males: 823.7 pills, females: 1211.1 pills). The results suggest that there may be gender differences in the utilization of non-operative therapies for symptomatic cervical stenosis prior to ACDF surgery.

Abstract
• Using cyanobacteria extracts at low doses reduces the toxicity risk in cucumber seeds. • Optimal doses of cytokinins and salicylic acid benefit the early plant growth stages. • Cyanobacterial siderophores favor plant growth during the seedling phase. • Strain Nostoc SAB-M612 stood out for their stimulant ability in cucumber seedlings.
This work clarifies some of the substances involved with the biostimulant effect shown by 28 cyanobacteria isolated from different aquatic environments. The production of salicylic acid, cytokinins, siderophores and phosphate solubilization were analyzed in vitro, as well as the phytostimulant/phytotoxic effect on watercress seeds at two different extract concentrations (0.5 and 0.2 mg mL−1). The most prominent plant growth promoting cyanobacteria were verified in vivo at two different doses (0.5 and 0.1 mg mL−1). 21.4 % and 7.1 % of the tested strains produced siderophores or phosphate solubilization, respectively. The production of salicylic acid was stood out for the strains Calothrix SAB-B797, Nostoc SAB-B1300 and Nostoc SAB-M612, while Nostoc SAB-M251 and Trichormus SAB-M304 were noticeable regard to cytokinin production. The highest values of germination occurred when the extracts were applied in low dose (0.5 mg mL−1). Nostoc SAB-M612 provoked the stimulation of aerial and radicular growth in cucumber seedlings.

Abstract
Success of composting as an ecological technology for organic waste management has allowed its implementation in the current circular economy models. However, composting on an industrial scale often shows drawbacks and peculiarities. In this work, a comparative analysis of 15 industrial composting facilities was carried out in which different anthropogenic organic waste were processed. Results showed that composting process on an industrial scale did not always evolve in a standard way. Monitoring parameters as well as enzymatic activity depended largely on the raw materials and were strongly linked to the transformation of nitrogen fractions. Despite the heterogeneity of the processes and raw materials, microbial activity managed to the optimal biotransformation, obtaining products that comply with the agronomic quality standards. This work represents a breakthrough in composting and provides new knowledge for better management of this process on an industrial scale.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES To assess for racial differences in opioid utilization prior to and after lumbar fusion surgery for patients with lumbar stenosis or spondylolisthesis. METHODS Clinical records from patients with lumbar stenosis or spondylolisthesis undergoing primary <3-level lumbar fusion from 2007 to 2016 were gathered from a comprehensive insurance database. Records were queried by International Classification of Diseases diagnosis/procedure codes and insurance-specific generic drug codes. Opioid use 6 months prior, through 2 years after surgery was assessed. Multivariate regression analysis was employed to investigate independent predictors of opioid use following lumbar fusion. RESULTS A total of 13 257 patients underwent <3-level posterior lumbar fusion. The cohort racial distribution was as follows: 80.9% white, 7.0% black, 1.0% Hispanic, 0.2% Asian, 0.2% North American Native, 0.8% "Other," and 9.8% "Unknown." Overall, 57.8% patients utilized opioid medications prior to index surgery. When normalized by the number opiate users, all racial cohort saw a reduction in pills disbursed and dollars billed following surgery. Preoperatively, Hispanics had the largest average pills dispensed (222.8 pills/patient) and highest average amount billed ($74.67/patient) for opioid medications. The black cohort had the greatest proportion of patients utilizing preoperative opioids (61.8%), postoperative opioids (87.1%), and long-term opioid utilization (72.7%), defined as use >1 year after index operation. Multivariate logistic regression analysis indicated Asian patients (OR 0.422, 95% CI 0.191-0.991) were less likely to use opioids following lumbar fusion. CONCLUSIONS Racial differences exist in perioperative opioid utilization for patients undergoing lumbar fusion surgery for spinal stenosis or spondylolisthesis. Future studies are needed corroborate our findings.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES To characterize regional variations in maximal nonoperative therapy (MNT) costs in patients suffering from lumbar stenosis or spondylolisthesis. METHODS Medical records from patients with symptomatic lumbar stenosis or spondylolisthesis undergoing primary ≤3-level lumbar decompression and fusion procedures from 2007 to 2016 were gathered from a large insurance database. Geographic regions (Midwest, Northeast, South, and West) reflected the US Census Bureau definitions. Records were searchable by International Classification of Diseases diagnosis/procedure codes, Current Procedural Terminology codes, and insurance-specific generic drug codes. Utilization of MNT, defined as cost billed, prescriptions written, and number of units disbursed, within 2-years prior to index surgery was assessed. RESULTS A total of 27 877 patients underwent 1-, 2-, or 3-level lumbar decompression and fusion surgery. Regional breakdown of the study cohort was as follows: South 62.3%, Midwest 25.2%, West 10.4%, Northeast 2.1%. Regional variations in the number of patients using nonsteroidal anti-inflammatory drugs (NSAIDs) (P < .0001), opioids (P < .0001), muscle relaxants (P < .0001), and lumbar steroid injections (P < .0001) were detected. A significant difference was identified in the regional MNT failure rates (P < .0001). The total cost associated with MNT prior to index surgery was $48 411 125 ($1736.60/patient), with the Midwest ($1943.83/patient) responsible for the greatest average spending. Despite comprising 62.3% of the cohort, the South was accountable for 67.5% of NSAID prescriptions, 64.6% of opioid prescriptions, and 71.2% of muscle relaxant prescriptions. CONCLUSIONS Regional differences exist in the costs of MNT in patients with lumbar stenosis and spondylolisthesis prior to surgery. Future studies should focus on identifying patients likely to fail prolonged nonoperative management.

Abstract
Time elapsed between removal from culture and embryo transfer (ET) can have a profound effect on the success of an invitro-produced (IVP) ET program. The embryo culture medium provides the necessary nutrients for embryo development and the use of media with a different nutrient composition to load embryos into straws could negatively affect embryo viability. The objective of the present study was to evaluate the effect of type of media used for embryo loading on pregnancy establishment and maintenance. Holstein heifers (n=800) were synchronized using a modified 5-day CO-Synch + controlled internal drug release (CIDR) as follows: Day −8: CIDR inserted, Day −3: CIDR removed, prostaglandin F2α treatment (500μg cloprostenol sodium), Day 0: gonadotrophin-releasing hormone (GnRH; 100μg of gonadorelin acetate). Five days after GnRH, heifers were evaluated by ultrasonography to determine presence of a corpus luteum (CL). Embryos were removed from culture on Day 7 (Day 0=fertilization), placed into tubes containing SOFaaci, and transported in an incubator (LabMix, WTA) to the transfer facility within 1.5h. Upon arrival embryos were removed from transport tubes and randomly assigned to be loaded into 0.25-mL straws containing either holding media (Vigro Holding Plus) or SOFaaci-HEPES. After loading into straws, embryos were placed in an ET gun and AI gun warmers set at 35°C until transfer by 1 of 5 technicians. Heifers with a CL were randomised for transfer of a fresh IVP embryo loaded into a straw containing either holding media or SOFaaci-Hepes on Day 7±1. Interval from embryo loading to transfer ranged from 1 to 3h. Pregnancy was determined by ultrasonography on Days 32 and 60. Data were analysed by logistic regression and included the fixed effects of loading media, embryo stage, embryo quality, interval between GnRH and ET, and biologically relevant interactions. Pregnancies per ET (P/ET) on Day 32 were not different between the groups in which embryos were loaded using holding media and those which used SOFaaci-Hepes, nor there were interactions between loading medium and embryo stage, embryo quality, or interval from GnRH to ET (P>0.10; Table 1). Pregnancies per ET (P/ET) on Day 60 were not different between the loading media groups, nor were there interactions between loading medium, embryo stage, and embryo quality, or interval from GnRH to ET (P>0.10). Pregnancy loss between Days 32 and 60 was not different between groups, nor there were interactions between loading media groups and any other factor (P>0.10). In conclusion, the use of either holding medium or SOFaaci-HEPES for fresh IVP embryo loading does not affect fertility; thus, both are suitable alternatives for loading of embryos into transfer straws.

Abstract
The aim of this study was to evaluate the effect of ruminal infusion with propylene glycol (PG) on the invitro embryo production (IVEP) of Holstein (Bos taurus) prepubertal heifers (7 to 8 months). For this study, 16 prepubertal heifers were distributed into two groups: Propylene Glycol Group (PGG; n=8) and Control Group (CG; n=7). Additionally, 8 pubertal heifers were used for the positive control group (PUB). All animals (n=23) underwent an ovum pickup (OPU) for follicular ablation on Day 0, followed by an FSH protocol treatment (160mg performed in 4 injections twice a day in decreasing doses, designated as D2PM, D3AM, D3PM, and D4AM). Animals from PGG received a ruminal infusion with 250mL of PG twice a day on Days 0, 1, 2, 3, and 4, using a drench. Animals from CG and PUB did not receive any additional treatment. On Day 5 all animals underwent another OPU, and oocytes were used for the IVEP (Sexing Technologies commercial laboratory). The produced embryos were transferred fresh to Holstein heifer recipients. Additionally, blood sampling was performed on D4PM (M1) and on the day of OPU (D5AM, M2) for insulin-like growth factor (IGF-1, via radioimmunoassay) and glucose (hexokinase) analysis. Data were analysed using the GLIMMIX procedure of SAS. No difference was observed between groups for number of recovered oocytes (CG: 14.28±1.9; PGG: 14.87±3.9; PUB: 10.50±2.2; P=0.24), number of viable oocytes (CG: 10.71±2.5; PGG: 10.75±2.7; PUB: 9.50±2.0; P=0.80), cleaved oocytes (CG: 7.71±1.5; PGG: 9.50±2.1; PUB: 6.25±1.4; P=0.14), cleavage rate (CG: 54.2% (7.7 out of 14.2); PGG: 64.1% (9.5 of 14.8); PUB: 59.0% (6.2 of 10.5); P=0.35) and number of blastocysts (CG: 1.71±0.5; PGG: 2.00±0.6; PUB: 3.12±1.0; P=0.71). Pubertal heifers had higher blastocyst rates compared with prepubertal heifers, regardless of PG treatment (CG: 11.9% (1.7 of 14.2); PGG: 13.5% (2 of 14.8); PUB: 29.5% (3.1 of 10.5); P=0.01). No difference was observed between groups for 30-day (CG: 41.7% (5 of 12); PGG: 46.7% (7 of 15); PUB: 42.9% (6 of 14); P=0.96) or 60-day pregnancy rates (CG: 41.7% (5 of 12); PGG: 33.3% (5 of 15); PUB: 42.9% (6 of 14); P=0.86). In addition, no difference was observed for pregnancy loss between 30 and 60 days (CG: 0.0% (0 of 12); PGG: 13.3% (2 of 15); PUB: 0.0% (0 of 14); P=0.99). Regarding metabolic blood analysis, no difference was observed for IGF-1 (ngmL−1) between groups (P=0.38), moment of sample collection (P=0.06), and interaction of group×moment (P=0.87; CG/M1: 263.36±15.2; CG/M2: 297.71±18.7; PGG/M1: 304.25±26.9; PGG/M2: 332.61±31.6; PUB/M1: 309.16±19.9; PUB/M2: 311.07±18.8). Glucose (mg dL−1) was higher (P=0.0001) for pubertal heifers (91.63±1.4) compared with the other groups (CG: 102.25±1.1; PGG: 107.71±3.5); however, no difference was observed for moment of sample collection (P=0.35) or interaction of group×moment (P=0.36). These data show that treatment with PG was not efficient to improve the IVEP of prepubertal Holstein heifers, embryos from prepubertal heifers treated with PG did not have increased pregnancy rate, and treatment did not increase IGF-1 or glucose blood levels.

Abstract
The timing of initiation of superstimulatory treatments relative to follicle wave emergence has been shown to affect ovulatory response and invivo embryo production. The significant increase of invitro embryo production (IVP) and the possibility of using pregnant animals as oocyte donors has created the need to optimise superstimulatory treatments for IVP in pregnant cattle. Thus, the objective of the present study was to evaluate the effect of synchronisation of follicle wave emergence before superstimulation for ovum pickup (OPU) and IVP in pregnant heifers. Pregnant (47-62 days of gestation) Holstein heifers (n=28) 19.5±0.3 months of age were assigned in a completely randomised design to one of two groups: synchronisation of follicular wave emergence by dominant follicle removal (DFR; all follicles >6mm) or untreated control (no DFR). Superstimulatory treatments were initiated 36h after DFR or at random stages of the follicular wave in the no-DFR group and consisted of the administration of 160mg of purified FSH (Folltropin-V, Vetoquinol) over four injections 12h apart as follows: 48.0, 42.7, 37.3, and 32.0mg. Ovum pickup was performed in all heifers 40h after the last purified FSH injection. Heifers were subjected to OPU for oocyte recovery, and the number of follicles was determined. Recovered oocytes were processed in groups by treatment, and IVP was performed. Differences between treatment groups were evaluated using generalised linear mixed models. Results are presented in Table 1 and are expressed as means±s.e.m. for data collected at the time of OPU or as proportions for embryo production results. The number of small follicles (<6mm) at the time of OPU was greater in the no-DFR group than in the DFR group (P=0.04). Conversely, there were no differences between treatments in the number of medium follicles (6-10 mm; P=0.17), large follicles (>10 mm; P=0.11), total follicles (P=0.93), total number of recovered oocytes (P=0.4), or number of viable oocytes (P=0.53). The mean oocyte percentage recovery rate was not different between heifers in the DFR (53.6±4.7%) and no-DFR (56.5±4.7%) groups (P=0.52). Both cleavage and blastocyst rate were greater (P<0.008) in the DFR group than in the no-DFR group; as a result, the number of transferable embryos per animal was 5.6 in the DFR group and 2.8 in the no-DFR group. In summary, initiation of superstimulatory treatments at the time of follicle wave emergence improves cleavage and blastocyst rates, thus leading to greater embryo production.

Abstract
BACKGROUND & OBJECTIVES Cutaneous leishmaniasis (CL) in Marrakesh-Safi region located in the central-south part of Morocco is a public health problem. This study assessed the efficiency of a microscopic examination method in establishing the diagnosis of CL and PCR for the characterization and identification of the circulating Leishmania strains in different CL foci of the study area. METHODS A total of 297 smears obtained from cutaneous lesions of suspected patients with CL were stained with May-Grünwald Giemsa (MGG) for microscopic examination. For each positive smear, genomic DNA was extracted and PCR-analysed, targeting the small subunit ribosomal ribonucleic acid (ssu rRNA) gene to detect Leishmania DNA. Then, the internal transcribed spacer 1 (ITS1) was amplified and sequenced in order to identify the Leishmania species. The sensitivity and specificity of the conventional microscopy with ssu rRNA gene were compared by Leishmania nested PCR (LnPCR) and ITS1 gene by ITS-PCR. RESULTS A total of 257 smears were positive in the microscopic examination, i.e. the detection rate of amastigotes by optical microscopy was 86.53% (257/297). The LnPCR was found to have a specificity and a sensitivity of 100%, each. Interestingly, the sequencing results showed that 99.61% (256/257) of the isolates had Leishmania tropica and 0.39% (1/257) had L. infantum infection. INTERPRETATION & CONCLUSION Though, classical microscopic examination is useful and economical, it is not sensitive enough, especially in endemic regions where several Leishmania species coexist. In such situations, PCR constitutes a complementary method for the identification of the causal species. The results indicate that both the L. tropica (dominant) and L. infantum are the causative agents of CL in the Marrakesh-Safi region. The rate of CL infection is high in Imintanout, and Chichaoua provinces. Hence, early diagnosis and prompt treatment of CL patients is necessary to prevent its extension to neighboring localities.

Abstract
Optimized fixed-time embryo transfer (FTET) protocols for synchronization of recipients have the potential to improve the overall efficiency and profitability of embryo transfer (ET) programs. The objective of the present study was to evaluate the effect of dose of gonadotrophin-releasing hormone (GnRH) at initiation of a 5-day synchronization protocol for FTET. Holstein heifers (n=2689) at two locations were synchronized using a 5-day CO-Synch protocol as follows: Day 0: CIDR inserted, Day 5: CIDR removed, prostaglandin (PG)F2α treatment (500μg cloprostenol), Day 6: PGF2α treatment, Day 8: GnRH (100μg of gonadorelin). On Day 0, at the time of CIDR insertion, heifers were assigned in a completely randomised design to the following groups: Single (a single dose of GnRH; 100μg of gonadorelin), Double (200μg of gonadorelin) or No GnRH (control). All heifers received an Estrotect patch placed on Day 5 and evaluated for signs of oestrus on Day 8. At location A, heifers were evaluated by ultrasonography 5 days after GnRH to determine presence and size of corpus luteum (CL), whereas at location B presence and location of CL were determined by transrectal palpation at the time of transfer. Heifers with a CL received an embryo 7±1 days after GnRH administration, and pregnancy was determined by ultrasonography 41 and 63 days after GnRH. Data were analysed by generalized linear mixed models. Oestrus expression was greater in heifers that received Single and Double GnRH than in the No GnRH group (P=0.001). Similarly, utilisation rate (number transferred per number treated) was greater for heifers in the Single and Double GnRH group than for those in the No GnRH group (P=0.02). Pregnancy data were analysed for a subset of recipients using data from Day 41 (n=2267) and Day 63 (n=2042). The analysis of fertility outcomes included as covariates the type of embryo (invitro fresh or frozen and invivo fresh or frozen), embryo stage, embryo quality, interval from GnRH to transfer, and oestrus expression. Pregnancies per embryo transfer (P/ET) at Days 41 and 63 were not different between treatment groups (P=0.86), and there was no interaction between type of embryo and treatment (P>0.15). Pregnancy loss between Days 41 and 63 was not different (P=0.49) between treatments groups. In conclusion, the removal of the initial GnRH from a 5-day FTET protocol resulted in a slight but significant reduction in the utilisation rate and the percentage of heifers showing oestrus. However, there was no detrimental effect on fertility. As a result, the overall cost of the FTET program can be reduced by eliminating the need for the initial GnRH treatment without compromising fertility.

Abstract
In the new European Waste Law, composting is proposed as one of the best options to properly manage organic waste of anthropogenic origin. Currently, the massive generation of this type of waste, as well as its heterogeneity, makes difficult in many cases control this process of degradation on an industrial scale. In this work, 15 facilities were selected based on 5 types of organic waste: Urban Solid Waste, Vegetable Waste, Sewage Sludges, Agrifood Waste and "Alpeorujo". The samples were collected in different thermal phases. The results revealed very different physicochemical and enzymatic profiles, as well as different degrees of humification depending on the process and the raw materials. However, parameters such as β-glucosidase, amylase, lignin/holocellulose ratio and humification rate showed similar trends in all cases. All of them could act as important indicators to evaluate the quality of a composting process, despite the heterogeneity of the starting materials.

Abstract
Abstract
Introduction
Atypical flutter ablation (AFL) is a challenging procedure with limited long-term benefits and not exempt from significant risks.
Purpose
To compare the efficacy and safety of this procedure in a population of octogenarian patients over a population of younger patients.
Methods
From 2015 to 2018, all patients in which AFL ablation was attempted were included. Activation and voltage mapping were used to define AFL circuit. Radiofrequency lesions were performed to operator's discretion until AFL termination. Programmed atrial stimulation was repeated to test inducibility, and any sustained induced arrhythmia was ablated. Follow-up included visits with ECG and/or 24h Holter-ECG at 3 and 12 months.
Results
107 patients (55 females) were included, 26 (24%) aged 80 or older (table). Successful ablation of the original circuit was achieved in 96% in both groups (acute success rate, p=0.973), with induction of other AFL circuits in 43% (46% octogenarians, 42% younger, p=0.708), successfully ablated in 88% in both groups (total success rate, p=0.952). No significant difference was detected in the rate of adverse events (8% in octogenarians versus 7% in younger, p=0.962), with a case of cardiac tamponade in the former, successfully resolved. After a mean follow-up of 11±12 months, 52 patients (49%) were free from recurrence, 13 (50%) in the octogenarian group and 39 (48%) in the younger, with an estimated median survival free from atrial arrhythmias of 26 months (95% CI: 4–48) in the octogenarian group and 18 months (95% CI: 5–32) in the younger group (p=0.716). After multivariate analysis, history of prior AF and indexed left atrial volume, but not age, predicted recurrence.
Demographical and clinical variables All patients (n=107) Octogenarians (n=26) No octogenarians (n=81) p-value Age (years) 69±13 83±3 65±11 <0.0001* Cardiomyopathy (%) 54 (50%) 13 (26%) 41 (51%) 0.956 Left ventricular ejection fraction (%) 60±13 57±17 61±11 0.24 Indexed left atrial volume (ml/m2) 45±19 48±14 43±19 0.55 Prior AF history 49 (46%) 7 (27%) 42 (52%) 0.026* Prior ablation procedures 53 (50%) 8 (31%) 45 (56%) 0.028* Prior cardiac surgery 30 (28%) 2 (8%) 28 (35%) 0.008* Left AFL origin (%) 87 (81%) 24 (92%) 63 (78%) 0.098 *Statistically significant difference.
Survival function
Conclusion
AFL ablation was as effective and safe in octogenarian as in younger ones, with a median survival time free from atrial arrhythmias of more than 2 years.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The purpose of this study is to assess change in opioid use before and after lumbar decompression and fusion surgery for patients with symptomatic lumbar stenosis or spondylolisthesis. METHODS A large insurance database was queried for patients with symptomatic lumbar stenosis or spondylolisthesis undergoing index lumbar decompression and fusion procedures between 2007 and 2016. This database consists of 20.9 million covered lives and includes private/commercially insured and Medicare Advantage beneficiaries. Opioid use 6 months preoperatively through 2 years postoperatively was assessed. RESULTS The study included 13 257 patients that underwent 1-, 2-, or 3-level posterior lumbar instrumented fusion. Overall, 57.8% of patients used opioids preoperatively. Throughout the 6-month preoperative period, 2 368 008 opioid pills were billed for (51.6 opioid pills/opioid user/month). When compared with preoperative opioid use, patients billed fewer opioid medications in the 2-year period postoperatively: 33.6 pills/patient/month (8 851 616 total pills). In a multivariate logistic regression analysis, obesity (odds ratio [OR] 1.10, 95% CI 1.004-1.212), preoperative narcotic use (OR 3.43, 95% CI 3.179-3.708), length of hospital stay (OR 1.02, 95% CI 1.010-1.021), and receiving treatment in the South (OR 1.18, 95% CI 1.074-1.287) or West (OR 1.26, 95% CI 1.095-1.452) were independently associated with prolonged postoperative (>1 year) opioid use. Additionally, males (OR 0.87, 95% CI 0.808-0.945) were less likely to use long-term opioid therapy. CONCLUSIONS This study demonstrates that reduction in opioid use was observed postoperatively in comparison with preoperative values in patients with symptomatic lumbar stenosis or spondylolisthesis that underwent lumbar decompression with fusion. Further prospective studies that are more methodologically stringent are needed to corroborate our findings.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The purpose of this study is to characterize the utilization and costs of maximal nonoperative therapies (MNTs) within 2 years prior to spinal fusion surgery in patients with symptomatic lumbar stenosis or spondylolisthesis. METHODS A large insurance database was queried for patients with symptomatic lumbar stenosis or spondylolisthesis undergoing index 1-, 2-, or 3-level lumbar decompression and fusion procedures between 2007 and 2016. This database consists of 20.9 million covered lives and includes private/commercially insured and Medicare Advantage beneficiaries. The utilization of MNTs within 2 years prior to index surgery was assessed by cost billed to the patient, prescriptions written, and number of units billed. RESULTS A total of 27 877 out of 3 423 114 (0.8%) eligible patients underwent posterior lumbar instrumented fusion. Patient MNT utilization was as follows: 11 383 (40.8%) used nonsteroidal anti-inflammatory drugs (NSAIDs), 19 770 (70.9%) used opioids, 12 414 (44.5%) used muscle relaxants, 14 422 (51.7%) received lumbar epidural steroid injection (LESI), 11 156 (40.0%) attended physical therapy/occupational therapy, 4005 (14.4%) presented to the emergency department, and 4042 (14.5%) received chiropractor treatments. The total direct cost associated with all MNTs prior to index spinal fusion was $28 241 320 ($1013.07 per/patient). LESI comprised the largest portion of the total cost of MNT ($15 296 941, 54.2%), followed by opioids ($3 702 463, 13.1%) and NSAIDs ($3 058 335, 10.8%). CONCLUSIONS Opioids are the most frequently prescribed and most used therapy in the preoperative period. Assuming minimal improvement in pain and functional disability after maximum nonoperative therapies, the incremental cost effectiveness ratio for MNT could be highly unfavorable.

Abstract
OBJECTIVE The aim of this study is to characterize the use and associated costs of maximal nonoperative therapy (MNT) received within 2-years before anterior cervical discectomy and fusion (ACDF) surgery in patients with symptomatic cervical stenosis. METHODS An insurance database, including private/commercially insured and Medicare Advantage beneficiaries, was queried for patients undergoing 1-level, 2-level, or 3-level ACDF procedures between 2007 and 2016. Research records were searchable by International Classification of Diseases diagnosis and procedure, Current Procedural Terminology, and generic drug codes. The use of MNTs within 2 years before index ACDF surgery was assessed by cost billed to patients, prescriptions written, and number of units billed. RESULTS Of 220,902 (7.16%) eligible patients, 15,825 underwent index surgery. Patient breakdown of the use of MNT modalities was as follows: 5731 (36.2%) used nonsteroidal antiinflammatory drugs; 9827 (62.1%) used opioids; 7383 (46.7%) used muscle relaxants; 3609 (22.8%) received cervical epidural steroid injection; 5504 (34.8%) attended physical therapy/occupational therapy; 1663 (10.5%) received chiropractor treatments; and 200 (1.3%) presented to the emergency department. During the 2-year preoperative period, there were 51,675 prescriptions for diagnostic cervical imaging. The total direct cost associated with all MNTs before ACDF was $16,056,556. Cervical spine imaging comprised the largest portion of the total MNT cost ($8,677,110; 54.0%), followed by cervical epidural steroid injection ($3,315,913; 20.7%) and opioids ($2,228,221; 13.9%). Opiates were the most frequently prescribed therapy (71,602 prescriptions). DISCUSSION Opioids are the most frequently prescribed and most used therapy in the preoperative period for cervical stenosis. Further studies and improved guidelines are necessary to determine which patients may benefit from ACDF earlier in the course of nonoperative therapies.

Abstract
OBJECTIVE With the costs related to the United States medical system constantly rising, efforts are being made to turn traditional inpatient procedures into outpatient same-day surgeries. In this study the authors looked at the various comorbidities and perioperative complications and their impact on readmission rates of patients undergoing outpatient versus inpatient 3- and 4-level anterior cervical discectomy and fusion (ACDF). METHODS This was a retrospective study of 337 3- and 4- level ACDF procedures in 332 patients (5 patients had both primary and revision surgeries that were included in this total of 337 procedures) between May 2012 and June 2017. In total, 331 procedures were analyzed, as 6 patients were lost to follow-up. Outpatient surgery was performed for 299 procedures (102 4-level procedures and 197 3-level procedures), and inpatient surgery was performed for 32 procedures (11 4-level procedures and 21 3-level procedures). Age, sex, comorbidities, number of fusion levels, pain level, and perioperative complications were compared between both cohorts. RESULTS Analysis was performed for 331 3- and 4-level ACDF procedures done at 6 different hospitals. The overall 30-day readmission rate was 1.2% (outpatient 3 [1.0%] vs inpatient 1 [3.1%], p = 0.847). Outpatients had increased readmission risk, with comorbidities of coronary artery disease (OR 1.058, p = 0.039), autoimmune disease (OR 1.142, p = 0.006), diabetes (OR 1.056, p = 0.001), and chronic kidney disease (OR 0.933, p = 0.035). Perioperative complications of delirium (OR 2.709, p < 0.001) and surgical site infection (OR 2.709, p < 0.001) were associated with increased risk of 30-day hospital readmission in outpatients compared to inpatients. CONCLUSIONS This study demonstrates the safety and effectiveness of 3- and 4-level ACDF surgery, although various comorbidities and perioperative complications may lead to higher readmission rates. Patient selection for outpatient 3- and 4-level ACDF cases might play a role in the safety of performing these procedures in the ambulatory setting, but further studies are needed to accurately identify which factors are most pertinent for appropriate selection.

Abstract
Abstract
Background: Almost a quarter of older adults in the United States will identify themselves as Hispanic/Latino by 2060. Our group has previously developed and validated a self-administered geriatric assessment tool which can be used to identify functional, psychological, social and cognitive impairments among older patients with various types of cancer. Among English-speaking older adults, completing this tool using paper/pencil or a tablet takes a median of 15-21 minutes (min), with < 10% needing assistance to answer it (Hurria, JOP 2016). However, the utilization of this tool among Spanish-speaking older adults has not been tested. We assessed the feasibility of administering a translated and validated Spanish version of our geriatric assessment tool for older Hispanic women with breast cancer, and identified their preferred format (tablet or paper/pencil).
Methods: Spanish-speaking women aged ≥ 65 years with a diagnosis of breast cancer completed the geriatric assessment twice on the same day. Patients were randomized into 3 groups: paper/pencil twice; tablet and paper/pencil in random order; and tablet twice. We assessed the proportion of patients requiring assistance to complete the geriatric assessment, the time needed to complete it, and the proportion of patients who thought the geriatric assessment was difficult/very difficult.
Results: 140 older women with breast cancer completed the geriatric assessment twice and were evaluable. Mean age was 71.6 years (SD 5.8), 53% had ≤ 8th grade education, 43% were married, 45% were retired, 32% were homemakers, and 6% were employed. The participants came from 13 different Spanish-speaking countries, although 70% were born in Mexico. For 90%, Spanish was their primary language, and 75% spoke only in Spanish at home. Regarding computer skills, 64% of the patients said they had none. 39% (n = 54) were unable to complete the geriatric assessment on their own; mean time to complete the geriatric assessment was 29 min (range 8-90); and 28% (n = 39) thought the geriatric assessment was difficult/very difficult. The most common reasons for needing assistance were difficulty understanding questions (39%) and visual problems (31%). Patients with ≤ 8th grade education took longer to complete the geriatric assessment (mean 37.2 vs 29.4 min, p < 0.01), and more often needed help completing the assessment (51% vs 19%, p < 0.01) than those with ≥9th grade education. 53% of the participants preferred using a tablet to answer the geriatric assessment, while 47% preferred paper/pencil.
Conclusions: A substantial proportion of Spanish-speaking older women with breast cancer required assistance to complete our self-administered geriatric assessment tool. This may be a consequence of the low educational level we found among this patient population. Tailoring assessments for diverse populations with particular attention to educational level is needed in multicultural settings.
