ABSTRACT

INTRODUCTION: This study explores how empowering human resource management (HRM) practices based on structural empowerment (access to opportunities, resources, support, and information) affect both personal initiative and job satisfaction of service employees through individual-level factors (psychological empowerment). METHODS: We conducted a cross-sectional survey study and collected 439 valid responses from service employees in Spain. The hypotheses were tested using structural equation modeling (SEM) with confidence intervals based on 10,000 resamples (i.e., bootstrapping technique). RESULTS: Our results showed that psychological empowerment partially mediated the relationship between structural empowerment and job satisfaction. It also fully mediated the relationship between structural empowerment and personal initiative at work. CONCLUSION: These findings emphasize the importance of HRM practices that can empower employees as key determinants of job satisfaction and personal initiative at service companies. Furthermore, a structural empowerment approach is a valid theoretical framework for studying and understanding employees' affective evaluations of work and, more specifically, their personal initiative.

ABSTRACT

Latinx gay, bisexual, and other men who have sex with men (LMSM) report lower pre-exposure prophylaxis (PrEP) use than their white, non-Latinx counterparts. We hypothesize that this disparity is partially attributable to social ecological factors that can be addressed via prevention interventions. In this retrospective study, we first examined data from 253 LMSM to determine whether theorized associations existed between acquisition of a PrEP prescription (uptake) in relation to several social ecological factors based on a conceptual framework of determinants of access to and uptake of PrEP for LMSM. We also explored relations between frequency of PrEP use (adherence) and social ecological factors with a subsample of 33 LMSM who had initiated PrEP 12 months prior to assessment. In this study, individual-level factors from this framework included age and socioeconomic status. Perceived access to medical care represented both individual- and community-level determinants of PrEP uptake and adherence. Interpersonal-level factors were social support and relationship status. Structural/cultural-level factors were sexual identity development status, the masculinity norm of heterosexual self-presentation, traditional Latinx masculine gender role beliefs of machismo and caballerismo, racial identity, and immigration status. Results indicated that older men and those who endorsed the synthesis/integration status of sexual identity development were more likely to acquire a PrEP prescription during their lifetime in comparison to peers. PrEP adherence was linked with being older, reporting higher socioeconomic status, reporting more appraisal social support, self-identifying as white-Latinx, being U.S.-born, and endorsing less sexual identity uncertainty and more heterosexual self-presentation. Results specify modifiable factors that may inform tailored, community-based prevention efforts to increase PrEP use and decrease existing HIV/AIDS disparities among LMSM.

ABSTRACT

Surgical menopause causes a sharp drop in estrogen levels in middle-aged women, thus preventing the gradual physiological adaptation that is characteristic of the perimenopause. Previous studies suggest that surgical menopause might increase the risk of dementia later in life. In addition, the transition to motherhood entails long-lasting endocrine and neuronal adaptations. We compared differences in whole-brain cortical volume between women who reached menopause by surgery and a group of women who reached spontaneous non-surgical menopause and determined whether these cortical differences were influenced by previous childbearing. Using surface-based neuroimaging techniques, we investigated cortical volume differences in 201 middle-aged women (134 women who experienced non-surgical menopause, 78 of whom were parous women; and 67 women who experienced surgical menopause, 39 of whom were parous women). We found significant atrophy in the frontal and temporal regions in women who experienced surgical menopause. Nulliparous women with surgical menopause showed significant lower cortical volume in the left temporal gyrus extending to the medial temporal lobe cortex, as well as in the precuneus bilaterally compared to parous women with surgical menopause; whereas our results revealed no significant differences between parous women with surgical menopause and both parous and nulliparous women who reached a non-surgical menopause. Furthermore, in the surgical menopause group, we found a negative correlation between cortical volume and age at first pregnancy in the temporal lobe. Our study suggests that the long-term brain remodeling of parity may mitigate the neural impact of the sudden drop in estrogen levels that characterizes surgical menopause.

ABSTRACT

BACKGROUND: Reduction of variability through process reengineering can improve surgical results for patients with type A acute aortic syndrome. We compare short-term results before and after implementation of an Aorta Code for patients with type A acute aortic syndrome who underwent surgery. METHODS: The Aorta Code was implemented in a 5-hospital healthcare network in 2019. This critical pathway was based on a simple diagnostic algorithm, ongoing training, immediate patient transfer, and treatment by an expert multidisciplinary team. We retrospectively compared all patients operated on in our center before (2005-2018) and after (January 2019 to February 2023) its implementation. RESULTS: One hundred two and 70 patients underwent surgery in the precode and code periods, respectively. In the code period the number of patients operated on per year increased (from 7.3 to 16.8), and the median elapsed time until diagnosis (6.5 hours vs 4.2 hours), transfer (4 hours vs 2.2 hours), and operating room (2.7 hours vs 1.8 hours) were significantly shorter (P < .05). Aortic root repair and total arch replacement were more frequent (66.7% vs 82.9% [P = .003] and 20.6% vs 40% [P = .001]). Cardiopulmonary bypass and ischemia times were also shorter (179.7 minutes vs 148.2 minutes [P = .001] and 105 minutes vs 91.2 minutes [P = .022]). Incidence of prolonged mechanical ventilation (53.9% vs 34.3%, P = .011), major stroke (17.7% vs 7.1%, P = .047), and 30-day mortality (27.5% vs 7.1%, P = .001) decreased significantly. CONCLUSIONS: An Aorta Code can be successfully implemented by using a standardized protocol within a hospital network. The number of cases increased; time to diagnosis, transfer, and operating room were reduced; and 30- day mortality significantly decreased.

ABSTRACT

Background: Little is known about patients with cancer presenting with acute chest discomfort to the emergency department (ED). Objectives: The aim of this study was to assess the prevalence of acute myocardial infarction (AMI), outcomes, and the diagnostic utility of recommended diagnostic tools in this population. Methods: Patients presenting with chest pain to the ED were prospectively enrolled in an international multicenter diagnostic study with central adjudication. Cancer status was assessed prospectively and additional cancer details retrospectively. Findings were externally validated in an independent multicenter cohort. Results: Among 8,267 patients, 711 (8.6%) had cancer. Patients with cancer had a higher burden of cardiovascular risk factors and pre-existing cardiac disease. Total length of stay in the ED (5.2 hours vs 4.3 hours) and hospitalization rate (49.8% vs 34.3%) were both increased in patients with cancer (P < 0.001 for both). Among 8,093 patients eligible for the AMI analyses, those with cancer more often had final diagnoses of AMI (184 of 686 with cancer [26.8%] vs 1,561 of 7,407 without cancer [21.1%]; P < 0.001). In patients with cancer, high-sensitivity cardiac troponin T (hs-cTnT) but not high sensitivity cardiac troponin I (hs-cTnI) concentration had lower diagnostic accuracy for non-ST-segment elevation myocardial infarction (for hs-cTnT, area under the curve: 0.89 [95% CI: 0.86-0.92] vs 0.94 [95% CI: 0.93-0.94] [P < 0.001]; for hs-cTnI, area under the curve: 0.93 [95% CI: 0.91-0.95] vs 0.95 [95% CI: 0.94-0.95] [P = 0.10]). In patients with cancer, the European Society of Cardiology 0/1-hour hs-cTnT and hs-cTnI algorithms maintained very high safety but had lower efficacy, with twice the number of patients remaining in the observe zone. Similar findings were obtained in the external validation cohort. Conclusions: Patients with cancer have a substantially higher prevalence of AMI as the cause of chest pain. Length of ED stay and hospitalization rates are increased. The diagnostic performance of hs-cTnT and the efficacy of both the European Society of Cardiology 0/1-hour hs-cTnT and hs-cTnI algorithms is reduced.

ABSTRACT

AIMS: Chronic obstructive pulmonary disease (COPD) is an important comorbidity in heart failure. The MIMO trial showed that patients with acute cardiogenic pulmonary edema (ACPE) treated with midazolam had fewer serious adverse events than those treated with morphine. In this post hoc analysis, we examined whether the presence/ absence of COPD modifies the reduced risk of midazolam over morphine. METHODS: Patients >18 years old clinically diagnosed with ACPE and with dyspnea and anxiety were randomized (1:1) at emergency department arrival to receive either intravenous midazolam or morphine. In this post hoc analysis, we calculated the relative risk (RR) of serious adverse events in patients with and without COPD. Calculating the CochranMantel-Haenszel interaction test, we evaluated if COPD modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. RESULTS: Overall, 25 (22.5%) of the 111 patients randomized had a history of COPD. Patients with COPD were more commonly men with a history of previous episodes of heart failure, than participants without COPD. In the COPD group, the RR for the incidence of serious adverse events in the midazolam versus morphine arm was 0.36 (95%CI, 0.1-1.46). In the group without COPD, the RR was 0.44 (95%CI, 0.22-0.91). The presence of COPD did not modify the reduced risk of serious adverse events in the midazolam arm compared to morphine (p for interaction =0.79). CONCLUSIONS: The reduced risk of serious adverse events in the midazolam group compared with morphine is similar in patients with and without COPD.

ABSTRACT

Cognitive emotion regulation (CER) strategies are useful in evaluating the risk of developing emotional disorders and that they may define subjects' styles. This study aims to explore the extent to which specific styles of CER strategies relate to the anxious and avoidant attachment dimensions in adults and whether such relationships operate similarly for women and men. Two hundred and fifteen adults (between 22 and 67 years old) completed the Spanish versions of the Cognitive Emotion Regulation Questionnaire and the Experiences in Close Relationships instrument. Cluster analysis, ANOVA and Student's t-test were used. Our results show that women and men can be successfully classified into two CER clusters (Protective and Vulnerable), distinguished by the higher use in the protective cluster of the CER strategies considered most adaptive and complex (Acceptance, Positive Refocusing, Refocus on Planning, Positive Reappraisal, and Putting into Perspective). However, only in women were the anxious and avoidant attachment dimensions significantly associated with CER style. In conclusion, from a clinical and interpersonal perspective, it is interesting to be able to predict the belonging to a Protective or Vulnerable coping style by analysing the CER strategies and to know their relationship with the adult affective system.

ABSTRACT

Coagulative nucleation in the copolymerization of methyl methacrylate-butyl acrylate (MMA-BA) via semicontinuous emulsion heterophase polymerization (SEHP) under monomer-starved conditions in latexes with high solid content (50.0 wt %) and low concentrations of surfactant is reported. The SEHP technique allows the obtention of latex with high colloidal stability and has potential industrial application in polymer synthesis. High instantaneous conversions (>90%) and a high-ratio polymerization rate/addition rate (Rp/Ra) ≥ 0.9 were obtained at low times until the final copolymerization, which confirmed the starved conditions in the systems at the highest surfactant concentrations. The particle size exhibited a linear size increment at conversions between 0 and 40% induced by homogeneous nucleation, a transition region between 40 and 50%, and non-linear behavior at higher conversions by coagulative nucleation. These three behaviors were also observed in the particle surfactant coverage area (Sc), Z-potential, particle coagulation rate (dNp/dt) by the Smoluchowski model, final particle size (Dpz), and number particle (Np) through the reaction. By means of transmission electron microscopy (TEM) images, the onset of coagulation was observed from 50% of conversion until the end of the reaction. In addition, in both processes of copolymerization, tacticity was displayed (mainly syndiotacticity).

ABSTRACT

This paper presents results concerning mechanistic modeling to describe the dynamics and interactions between biomass growth, glucose consumption and ethanol production in batch culture fermentation by Kluyveromyces marxianus (K. marxianus). The mathematical model was formulated based on the biological assumptions underlying each variable and is given by a set of three coupled nonlinear first-order Ordinary Differential Equations. The model has ten parameters, and their values were fitted from the experimental data of 17 K. marxianus strains by means of a computational algorithm design in Matlab. The latter allowed us to determine that seven of these parameters share the same value among all the strains, while three parameters concerning biomass maximum growth rate, and ethanol production due to biomass and glucose had specific values for each strain. These values are presented with their corresponding standard error and 95% confidence interval. The goodness of fit of our system was evaluated both qualitatively by in silico experimentation and quantitative by means of the coefficient of determination and the Akaike Information Criterion. Results regarding the fitting capabilities were compared with the classic model given by the logistic, Pirt, and Luedeking-Piret Equations. Further, nonlinear theories were applied to investigate local and global dynamics of the system, the Localization of Compact Invariant Sets Method was applied to determine the so-called localizing domain, i.e., lower and upper bounds for each variable; whilst Lyapunov's stability theories allowed to establish sufficient conditions to ensure asymptotic stability in the nonnegative octant, i.e., R+,03. Finally, the predictive ability of our mechanistic model was explored through several numerical simulations with expected results according to microbiology literature on batch fermentation.

ABSTRACT

OBJECTIVES: The midazolam vs morphine (MIMO) trial showed that patients treated with midazolam had fewer serious adverse events than those treated with morphine. In many patients with acute pulmonary edema, the left ventricular ejection fraction (LVEF) is preserved, at 50% or higher. We aimed to determine whether left ventricular (LV) systolic dysfunction (D), defined by an LVEF of less than 50%, modifies the protective effect of midazolam vs morphine. MATERIAL AND METHODS: The MIMO trial randomized 111 patients with acute pulmonary edema to receive intravenous midazolam in 1-mg doses to a maximum of 3 mg (n = 55) or morphine in 2- to 4-mg doses to a maximum of 8 mg (n= 56). We calculated the relative risk (RR) for a serious adverse event in patients with and without systolic LVD. RESULTS: LVEF was preserved in 84 (75.7%) of the patients with acute pulmonary edema. In patients with systolic LVD, 4 patients (26.9%) in the midazolam arm vs 6 (50%) in the morphine arm developed serious adverse events (RR, 0.53; 95% CI, 0.2-1.4). In patients without systolic LVD, 6 patients (15%) in the midazolam arm vs 18 (40.9%) in the morphine arm experienced such events (RR, 0.37; 95% CI, 0.16-0.83). The presence of systolic LVD did not modify the protective effect of midazolam on serious adverse effects (P=.57). CONCLUSION: The effect of midazolam vs morphine in protecting against the development of serious adverse events or death is similar in patients with and without systolic LVD.


OBJETIVO: El ensayo clínico MIMO demostró que los pacientes con edema agudo de pulmón (EAP) tratados con midazolam tenían menos eventos adversos graves (EAG) que los tratados con morfina. Muchos pacientes con EAP tienen fracción de eyección del ventrículo izquierdo (FEVI) preservada ($ 50%). El objetivo fue conocer si la disfunción sistólica ventricular izquierda (DSVI) (fracción eyección ventrículo izquierdo 50%) modifica el efecto protector del midazolam frente a la morfina. METODO: El estudio MIMO asignó al azar 111 pacientes con EAP a tratamiento con midazolam (dosis de 1 mg intravenosa, hasta una dosis máxima de 3 mg, n = 55) o morfina (dosis de 2-4 mg, hasta una dosis máxima de 8 mg, n = 56). Se calculó el riesgo relativo (RR) de padecer un EAG en pacientes con y sin DSVI. RESULTADOS: La FEVI preservada estuvo presente en 84 (75,7%) pacientes con EAP. En el grupo con DSVI, 4 pacientes (26,9%) en el brazo midazolam frente a 6 (50%) en el brazo morfina presentaron EAG (RR = 0,53; IC 95: 0,2-1,4). En el grupo sin DSVI 6 pacientes (15%) del brazo midazolam frente a 18 (40,9%) del brazo morfina presentaron EAG (RR = 0,37; IC 95: 0,16-0,83). La DSVI no modificó el efecto protector del midazolam en la aparición de EAG con respecto a la morfina (p = 0,57). CONCLUSIONES: En pacientes con EAP el efecto protector del midazolam sobre la morfina en la aparición de EAG y EAG o muerte fue similar en pacientes con y sin DSVI.

ABSTRACT

BACKGROUND AND IMPORTANCE: The MIMO clinical trial showed that patients with acute cardiogenic pulmonary edema (ACPE) treated with midazolam had fewer serious adverse events than those treated with morphine. Atrial fibrillation (AF) is a common comorbidity in heart failure and affects patient's outcome. OBJECTIVE: The primary endpoint of this substudy is to know if AF modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. The first secondary endpoint is to know if AF modified the reduced risk of serious adverse events or death at 30 days in the midazolam arm. The second secondary objective of this substudy is to analyze whether AF modified the reduced risk of midazolam against morphine on the total number of serious adverse events per patient. DESIGN: We conducted a secondary analysis of the MIMO trial. Patients more than 18 years old clinically diagnosed with ACPE and with dyspnea and anxiety were randomized (1:1) at emergency department arrival to receive either intravenous midazolam or morphine. OUTCOME MEASURES AND ANALYSIS: In this post hoc analysis, we calculated the relative risk (RR) of serious adverse events in patients with and without AF. Calculating the Cochran-Mantel-Haenszel interaction test, we evaluated if AF modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. MAIN RESULTS: One hundred eleven patients (median = 78.9 years; IQR, 72.3-83.7; women, 52.2%) were randomized in the MIMO trial, 55 to receive midazolam and 56 to morphine. All randomized patients received the assigned drug and there were no losses to follow-up. Forty-four patients (39.6%) had AF. In the AF group, the RR for the incidence of serious adverse events in the midazolam versus morphine arm was 0.42 (95% CI, 0.14-1.3). In the group without AF, the RR was 0.46 (95% CI, 0.21-1). The presence of AF did not modify the reduced risk of serious adverse events in the midazolam arm compared with morphine ( P for interaction = 0.88). CONCLUSION: This post hoc analysis of the MIMO trial suggests that the reduced risk of serious adverse events in the midazolam group compared to morphine is similar in patients with and without AF.

ABSTRACT

Research about harmonious passion as a personal resource that can have a protective effect in situations of stress and burnout is scarce but growing. Considering the job demands-resources (JD-R) model, the present study aims to address the above gaps by exploring the moderating role of harmonious passion at work in the relationship between burnout (physical fatigue, cognitive weariness, and emotional exhaustion) and intrinsic job satisfaction. The study sample consisted of 748 workers from service organizations (front-line employees) in southern Spain (Mage = 35.51, SD = 10.06, 52% women). Using statistical program R (R Core Team, 2022), the results of the regression models showed the moderating role of harmonious passion on the negative relationships between physical fatigue and intrinsic job satisfaction. In particular, at high levels of physical fatigue, employees with high scores on harmonious passion at work presented higher levels of intrinsic satisfaction compared with employees with low passion at work. That is, although service employees have high levels of physical fatigue, when they are passionate, they still possess satisfaction with their work. Therefore, our findings extend the JD-R theory by considering harmonious passion as a motivational resource that reduce feelings of burnout in service employees. Hence, it shows the importance of promoting the autonomous internalization of work, (through, i.e., job enrichment), which allows the development of harmonious passion at work and, therefore, increasing intrinsic job satisfaction.

ABSTRACT

The archetypical folded shape of the human cortex has been a long-standing topic for neuroscientific research. Nevertheless, the accurate neuroanatomical segmentation of sulci remains a challenge. Part of the problem is the uncertainty of where a sulcus transitions into a gyrus and vice versa. This problem can be avoided by focusing on sulcal fundi and gyral crowns, which represent the topological opposites of cortical folding. We present Automated Brain Lines Extraction (ABLE), a method based on Laplacian surface collapse to reliably segment sulcal fundi and gyral crown lines. ABLE is built to work on standard FreeSurfer outputs and eludes the delineation of anastomotic sulci while maintaining sulcal fundi lines that traverse the regions with the highest depth and curvature. First, it segments the cortex into gyral and sulcal surfaces; then, each surface is spatially filtered. A Laplacian-collapse-based algorithm is applied to obtain a thinned representation of the surfaces. This surface is then used for careful detection of the endpoints of the lines. Finally, sulcal fundi and gyral crown lines are obtained by eroding the surfaces while preserving the connectivity between the endpoints. The method is validated by comparing ABLE with three other sulcal extraction methods using the Human Connectome Project (HCP) test-retest database to assess the reproducibility of the different tools. The results confirm ABLE as a reliable method for obtaining sulcal lines with an accurate representation of the sulcal topology while ignoring anastomotic branches and the overestimation of the sulcal fundi lines. ABLE is publicly available via https://github.com/HGGM-LIM/ABLE .

ABSTRACT

BACKGROUND: The lateral sprain of the ankle is a very frequent injury in the population in general, appearing in the emergency services frequently. The general objective was to review the current clinical practice guidelines (CPGs) on management and treatment of ankle sprains, assess their quality, analyze the levels of evidence and summarize the grades of recommendation. METHODS: A systematic search of the literature in relevant databases with the search terms "ankle," "sprain," "practice guideline," and "guideline" was carried out. There were included those guidelines that had the system of grades of recommendation and level of evidence concerning to management and treatment of ankle sprain. The quality of the guides was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. RESULTS: Seven clinical practice guides were included in this review. The AGREE II scores ranged from 42% to 100%, with only six CPGs explicitly declaring the use of a systematic methodology. Seventeen recommendations were extracted and summarized. DISCUSSION: Six of the recommendations analyzed present enough evidence to be applied in clinical practice and are highly recommended for ankle sprain management: Ottawa rules, manual therapy, cryotherapy, functional supports, early ambulation, short term NSAIDs and rehabilitation.

ABSTRACT

Since the mid-20th century, the study of Self-Regulated Learning (SRL) has aimed to identify the distinctive characteristics that enable individuals to acquire new knowledge and skills under their control. The theory of Internal Self-Regulation vs. External-Regulation in Learning (SRL vs. ERL; 2017) has postulated that a large number of self-regulatory variables are mediated by regulated/non-regulated or dysregulated features of the context. After signing their informed consent, a total of 616 university students completed validated instruments of SRL vs. ERL, behavioral regulation (SRB), regulatory teaching (RT), and metacognitive study control strategies (SRS). Using an ex-post facto design and correlation, regression, structural equation model and mediation analyses, the present research aimed to establish multicausal predictive relationships among the analyzed variables. Results indicated positive predictive effects between the external regulation variables on the self-regulation variables in learning [regulation (SRL)/non-regulation (NRL)/dysregulation (DRL)]; as well as positive predictive effects between SRL on SRB, RT and metacognitive SRS. Additionally, external regulation (ERL) not only predicted but mediated numerous relations among the variables studied. Other findings and important considerations for future research in the field of self-regulation are discussed.

ABSTRACT

BACKGROUND: The main purpose was to evaluate the changes in peripapillary retinal nerve fiber layer (RNFL) thickness and vessel density (VD) in post-COVID-19 patients during 12-month follow-up. METHODS: In this prospective study, patients with COVID-19 who were attended in the Hospital Clinico San Carlos (Madrid, Spain) were included. All patients underwent a complete ophthalmological examination, optic nerve head optical coherence tomography (OCT), and OCT angiography (OCTA) using the Cirrus HD-OCT 5,000 with AngioPlex OCTA 1, 3, and 12 months after laboratory-confirmed diagnosis. Sociodemographic data, medical history, disease severity, and laboratory workup were registered. RESULTS: A total of 180 eyes of 90 patients with SARS-CoV-2 infection were included; the mean age was 55.5 ± 8.9 years, and 46 patients (51%) were females. The mean visual acuity was 0.76 ± 0.16, and no abnormalities attributable to SARS-CoV-2 were detected in the ocular or fundus examination. No differences in the OCT and OCTA data were found between severity groups in each visit (all P > 0.05). Overall, there was a decrease in RNFL global thickness ( P < 0.001) from the first to the last visit, and an increase in VD and flux index was noted in some sectors at the 12-month examination. A significant correlation was detected at 12 months between vascularization parameters and RNFL thickness. CONCLUSIONS: One year after SARS-CoV-2 infection, changes in peripapillary RNFL thickness and vascularization occur, possibly indicating a recovery in such parameters.

ABSTRACT

OBJECTIVE: Neuroimaging studies in children with ADHD indicate that their brain exhibits an atypical functional connectivity pattern characterized by increased local connectivity and decreased distant connectivity. We aim to evaluate if the local and distant distribution of functional connectivity is also altered in adult samples with ADHD who have never received medication before. METHODS: We compared local and distant functional connectivity between 31 medication-naïve adults with ADHD and 31 healthy controls and tested whether this pattern was associated with symptoms severity scores. RESULTS: ADHD sample showed increased local connectivity in the dACC and the SFG and decreased local connectivity in the PCC. CONCLUSION: Results parallel those obtained in children samples suggesting a deficient integration within the DMN and segregation between DMN, FPN, and VAN. These results are consistent with the three main frameworks that explain ADHD: the neurodevelopmental delay hypothesis, the DMN interference hypothesis and multi-network models.

ABSTRACT

Cassava is a staple food used in many countries around the world, despite deficiencies in micronutrients such as provitamin A carotenoids. Unfortunately, improvement of the cassava nutritional content by use of conventional breeding is slow and difficult. Therefore, there is an urgent need to develop and standardize protocols using biotechnological tools to improve cassava. The Alliance of Biodiversity International and the International Center for Tropical Agriculture (CIAT) have worked on cassava genetic transformation over the last 30 years. Here, we describe, step by step, the procedures used for genetic transformation of cassava variety TMS60444, to improve carotenoids and other traits. This protocol includes stock setup, reagents, media preparation, materials, and equipment, for the genetic transformation of embryogenic tissues. The main expected output in publishing this protocol is to provide the basis for a reproducible and reliable method to genetically modify and/or gene edit Latin American and Asian cassava varieties.

ABSTRACT

AIMS: Benzodiazepines have been used as safe anxiolytic drugs for decades and some authors have suggested they could be an alternative for morphine for treating acute cardiogenic pulmonary oedema (ACPE). We compared the efficacy and safety of midazolam and morphine in patients with ACPE. METHODS AND RESULTS: A randomized, multicentre, open-label, blinded endpoint clinical trial was performed in seven Spanish emergency departments (EDs). Patients >18 years old clinically diagnosed with ACPE and with dyspnoea and anxiety were randomized (1:1) at ED arrival to receive either intravenous midazolam or morphine. Efficacy was assessed by in-hospital all-cause mortality (primary endpoint). Safety was assessed through serious adverse event (SAE) reporting, and the composite endpoint included 30-day mortality and SAE. Analyses were made on an intention-to-treat basis. The trial was stopped early after a planned interim analysis by the safety monitoring committee. At that time, 111 patients had been randomized: 55 to midazolam and 56 to morphine. There were no significant differences in the primary endpoint (in-hospital mortality for midazolam vs. morphine 12.7% vs. 17.9%; risk ratio[RR] 0.71, 95% confidence interval [CI] 0.29-1.74; p = 0.60). SAE were less common with midazolam versus morphine (18.2% vs. 42.9%; RR 0.42, 95% CI 0.22-0.80; p = 0.007), as were the composite endpoint (23.6% vs. 44.6%; RR 0.53, 95% CI 0.30-0.92; p = 0.03). CONCLUSION: Although the number of patients was too small to draw final conclusions and there were no significant differences in mortality between midazolam and morphine, a significantly higher rate of SAEs was found in the morphine group.
