Published: October 2019

ABSTRACT: Salami is a ready-to-eat (RTE) product frequently purchased at street fairs in Porto Alegre. Salmonella enterica, Listeria monocytogenes, and coagulase-positive Staphylococcus (CPS) are important causes of foodborne disease and can be transmitted through the consumption of RTE foods. The aim of this study was to evaluate the presence of these pathogens in salami sold at street fairs. Ninety salami samples from three commercial brands available at street fairs were analyzed by routine bacteriological methods for Salmonella spp. and Listeria spp., as well as enumeration of CPS. In addition, two samples from each commercial brand were analyzed for water activity (aw). Samples of brand A showed aw values (0.938 and 0.942) above those set by the legislation, while brand B (0.849 and 0.860) and brand C (0.826 and 0.854) were compliant. Microbiological analyses showed that 67.7% were negative to all investigated bacteria. Salmonella Typhimurium was isolated from 4.4% (4/90) of salami samples, all from commercial brand A. Listeria monocytogenes was detected in 3.3% (3/90) of samples, from commercial brands B and C. Moreover, 7.7% (7/90) of samples contained CPS populations non-compliant with legislation. Although the great majority of salami sold at street fairs of Porto Alegre was compliant with standards, S. enterica, L. monocytogenes, and CPS ≥ 5 × 103 cfu.g-1 could be found in this RTE product. Therefore, control measures in the processing industry and consumer’s education about foodborne illness prevention should be maintained.

ABSTRACT Objective: To examine the relationship between nutritional status and dental caries of schoolchildren from Sobral, Ceará, Braszil. Methods: Dental health and nutritional status of 92 children studying in two different schools and aging 5 years old were evaluated. The nutritional status was evaluated using the Body Mass Index (BMI), and the dental health status was evaluated using the Decayed, Missing, and Filling Tooth Index (DMFT-index). An interview with the parents of the children was also performed to investigate the socioeconomic profile and nutritional habits of the children. Results: A DMFT-index of 1.97 was found, and 39.6% of the childrenpresented overweight. Higher prevalence of dental caries was associated with low income, public schools, and less schooled parents. The variable overweight presented the inverse situation found for dental caries. Moreover, it was observed lower prevalence of caries in overweight children. Conclusion: Dental caries and nutritional status exhibited different behaviors in the population studied, which were driven by the sociodemographic profile of the family.

ABSTRACT Objective: to assess the difficulty in swallowing medications and correlate it with age and gender in healthy adults and elderly. Methods: a total of 439 asymptomatic healthy volunteers (270 females and 169 males), who were not taking any medication on a regular basis, aged from 20 to 84 years, were questioned as for dysphagia, by using the Eating Assessment Tool (EAT-10). Question number five of the EAT-10, specifically, approached the difficulty in swallowing drugs, considering zero as “no swallowing problem” and 1 to 4 as “some degree of difficulty” (4 as great difficulty).The chi-square test (x2) was used for the statistical analysis. Results: a total of 365 (83%) volunteers reported having no difficulty in swallowing medications (89% of men and 80% of women), whereas 74 (17%) reported some degree of difficulty (11% of men and 20% of women)(p = 0.01). These represented 20% of those aged between 20 and 49, and 9% of those aged 50 and over (p = 0.02). Conclusion: in this study, it was observed that both age and gender influence on medication swallowing, a difficulty more frequent among women and young adults. Some degree of difficulty was reported by 17% of the volunteers.

Published: October 2019

ABSTRACT Objective: to verify the association between nutritional status and the occurrence of oropharyngeal dysphagia in individuals with cerebral palsy. Methods: a cross-sectional, quantitative study with people aged between two and 20 years. Neuromotor impairment, occurrence and degree of dysphagia, anthropometry, food consumption, feeding route, diet fractionation and consistency were evaluated. Swallowing evaluation was performed by a skilled speech-language-hearing therapist, through the Clinical Evaluation Protocol of Pediatric Dysphagia (PAD-PED, Portuguese acronym).The statistical analysis was performed adopting p<0.05%. Results: 40 subjects with a median of 8.7 (5.45-14.5) years, 65% of whom were males. Concerning neuromotor impairment, 72.5% were classified at levels IV and V. The prevalence of dysphagia was 70%, the feeding route being predominantly oral (77.5%) with a normal diet consistency (55%). In the growth curves, all of them were classified within an adequate height for their age. As for weight, body mass index and skinfolds, 82.5%, 85% and 62.5% were eutrophic, respectively. Statistically significant association was found between dysphagia and body mass index (p=0.018). The mean daily caloric and proteic intake was 1427.29±338.62 kcal and 56.86±17.57 grams, respectively. Statistically significant association was found between the feeding route and the amount of protein ingested daily (p=0.041). Conclusion: most subjects presented oropharyngeal dysphagia and more severe motor impairment; they were fed orally with a normal diet consistency. It was observed that the greater the difficulty in swallowing, the greater the impairment of nutritional status.

Published: October 2019

Abstract Objective: To describe the reasons for the disposal of blood in the coordinating blood center of the State of Paraná and to estimate the financial costs resulting from potentially avoidable discards. Method: A descriptive, retrospective and documentary analysis, with data related to the period from 2010 to 2015 of a Brazilian coordinating blood center collected from a governmental database and analyzed by descriptive statistics. This study was approved by the Ethics Research Committee (CAEE 63074916.0.0000.5225). Results: 101,813 units were discarded, representing 22.3% of the total of 455,684 produced; plasma was the most discharged blood component. The main reason for discarding was lipemia (35.8%); the analysis showed that 56.9% of the disposals were considered potentially avoidable with an estimated paid value of approximately US$2 million. Conclusion: The expressive potential of avoidance of disposal of blood units and blood components highlights the importance of planning actions aiming at their best use, contributing to the reduction of amounts paid for these processes.

Abstract Chain of Custody implies adequate collection, recording, and storage of the vestige of sexual violence, guaranteeing the reliability of the material that will be forwarded as expert evidence. Its implementation in the Unified Health System has faced challenges. Objective: To know the attendance to victims of sexual violence in the public maternity of Federal District and evaluate the knowledge of the team about the legislation on a chain of custody. Method: Cross-sectional, quantitative, and descriptive study with 134 medical and nursing professionals working in the obstetric emergency, who answered a questionnaire, submitted to descriptive statistical analysis and the Qui-Square Test. Results: Of the 78.95% of professionals who reported attending to victims of sexual violence, 25.71% consulted in 10 minutes, and 14.18% received specific training. The situational diagnosis reveals that the care is superficial, centered on medical issues, and the collection of vestiges is non-existent. Conclusion and implications to nursing practice: A generalized change of posture is necessary so that it is possible to implant the chain of custody in the maternity studied. It is essential to develop care beyond medical issues, and which includes forensics. It is suggested a collaborative action between physicians and nurses, with nursing as the epicenter of this process.
“Réquiem para um solitário”: migrações, exílio de si, melancolia
Authors: Magalhães Carlos Augusto
Published: October 2019

Resumo A partir, especialmente, da segunda metade do século XX, os deslocamentos espaciais e as migrações ocupam importantes lugares na literatura brasileira. Os personagens das narrativas vivenciam situações de dificuldades que os colocam à prova, fazendo-os, em última análise, buscar a si e à própria essência para suportar os estranhamentos diversos, a frieza e a indiferença do Outro e a separação do solo e cultura nacionais. Para além dos trânsitos geográficos, há degredos mais densos, pois que identificados com incidências subjetivas que interferem nos espaços mais íntimos do sujeito que vive situações de exílio de si próprio. Este artigo analisa tais aspectos no conto “Réquiem para um solitário”, de Samuel Rawet, em que o protagonista, um judeu polonês que veio para o Brasil, vivencia não só o isolamento do imigrante, mas também, e principalmente, a solidão da experiência melancólica.

Published: October 2019

Abstract The greatest diversity of ferns occurs in the tropics, where approximately three in four of the species are found. In the Brazilian flora, the ferns have megadiversity, being an important plant group. The objective was to evaluate the spores germination of ferns Polypodium aureum in different types of culture medium. The sporangia were removed from fertile fronds and sterilized with sodium hypochlorite 0.57% during 30 minutes. After sterilization, the sporangia were seeded in culture media agar, MS, SH, White and B5. The experimental design was completely randomized being composed of 5 treatments (agar media, B5, SH, White and MS) and 10 replications. The ratings occurred every 3 days over a period of 45 days, counting the number of spores germinated. After this period, the germination percentage, germination time on medium, germination speed index and timing of germination were calculated. The germination percentage and the index of synchronization have not changed in function of different culture media. The medium White presented the highest average for the germination speed index whereas the agar media, MS, SH and B5 had the same germination speeds. The percentage of mortality was higher in MS medium, the White medium presented the lowest percentage of mortality, and the media composed by agar, SH and B5 showed intermediate values. The lowest average germination time occurred at the media SH and B5, since the environment composed by agar showed higher average germination time. The media MS and White showed similar results to the agar, SH and B5. Based on the obtained results, it can be concluded that the White medium is the most effective on the germination of spores of Polypodium aureum.

Published: October 2019

Abstract Several authors report that potassium (K) is the nutrient absorbed in greater amounts by gerbera plants. Thus, objective of determining the concentration of Kin the solution of substrates for growing potted gerbera, quantified by the Cardy Horiba C-131 and an atomic absorption spectrophotometer, correlating them with each other and with the plant leaf content. The experiment was carried out in a greenhouse. The experimental design was in randomized complete blocks using a 5×2 factorial scheme (5 substrates/2 cultivars) and four replications. Cherry and Red gerbera cultivar seedlings with four final leaves were transplanted into pots, filled with the substrates and acclimated for 30 days. After acclimation, the K content in the substrate solution extracted by the “PourThru” methodology was evaluated every two weeks using the Cardy Horiba C-131 portable ion meter and an atomic absorption spectrophotometer, as well as the K content in the leaves of gerbera plants. The solution of the commercial substrate had higher concentrations of K in relation to the others in the two forms of measurement, which is directly related to the high initial contents of the nutrient in this substrate. This is directly related to the high initial K contents in the substrate. Greater values of K were obtained for the cultivar Red, both in the solution and in the leaves. The K concentration of the substrate solution cultured with gerbera plants quantified by the Cardy Horiba C-131 and atomic absorption spectrophotometry correlated significantly with each other and showed a low correlation with the content of this nutrient in the plant tissue.

Abstract Understanding the in vitro performance of royal poinciana explants cultured in media supplemented with different types and concentrations of cytokinins may aid in the optimization of regeneration systems established for this woody species. In the present study we evaluate the in vitro performance of royal poinciana cotyledonary explants cultured in the presence of high concentrations of 6-benzyladenine (BA) and kinetin (KIN). Cotyledonary segments obtained from in vitro germinated seedlings were inoculated in Murashige and Skoog (MS) medium, supplemented with different concentrations (1, 2, 4, 8 mg L-1) of BA or KIN. In the control treatment, no plant growth regulators (PGRs) were added. After 40 days of culture, regardless of the concentration used, the treatments supplemented with BA presented higher calli percentage and fresh mass compared to treatments supplemented with KIN. Adventitious shoots were mainly observed in BA-treatments. Histological analysis showed that adventitious shoots formed at the periphery of callus formed from mesophyll cells in the regions of the explant sectioning. The results obtained provide new information for the establishment of a micropropagation system for royal poinciana, an important ornamental tree species.
Influence of volume container in the production of rhizomes in Seemannia (Gesneriaceae)
Authors: Bologna Paula , Stancanelli Santiago
Published: October 2019

Abstract Seemannia Regel belongs to the Gesnereacieae family. It is an herbaceous perennial plant with colorful and brilliant flowers that produces fleshy scaly rhizomes with axillary dormant buds. The objective of this study was to evaluate the effect of the volume of the container in the production and the quality of the rhizomes. Plants of a select hybrid of Seemnania were used. Three volume of container were tested: v1 of 1 L, v2 of 1,5 L and v3 of 2 L. Plants were cultivated in the containers following a conventional management. Dry matter, production (number and weight of rhizomes) and quality of the rhizomes were recorded. The rhizomes were classified into four qualities (A, B, C, D) according to the length and width, and the number of the scales. All data was subject to statistical analysis. Dry matter, weight and number of rhizomes increased as the volume of container increased. The v3 container recorded the highest values for these three parameters. Major volume of container, major was the development of vegetative mass and consequently the number and the weight of rhizomes were higher. In regard to the qualities of the rhizomes, v1 and v3 treatments had a better proportion of A rhizomes (the bigger size) compared to v2 treatment. The knowledge of the rhizome quality can be useful to the growers in order to select the best rhizome size for a good production. The v3 treatment recorded the highest number of A rhizomes, that we consider a good quality, because it has the bigger size with more scales and consequently more propagules.

Published: October 2019

Abstract Gladiolus (Gladiolus x grandiflorus Hort.), also called as Palma-de-Santa-Rita, is culturally known in Brazil as the All Soul's' Day flower. In recent years, it has also become popular in other special dates due to its robustness, liveliness, and magnificence. However, there are challenges regarding the cut flower production, since the largest producer investment is the corm acquisition. Due to the insufficiency of technical information, there are no fully established corm production protocols for gladiolus. Therefore, this technical article has the objective of bringing information related to the gladiolus corms production technique, in view of the sustainability of the production.

The study of the maximum shear stress of the composition of pyrophyllite - clay component – water at elevated temperatures
Authors: Abdrakhimov V. Z.
Published: October 2019

A sharp decrease in the ultimate shear stress in the range of 20‒80 °C is observed when obtaining samples from the clay component without descendents. This contributes to the appearance of cracks and defects in the samples. The use of pyrophyllite in ceramic masses in obtaining samples ensures a gradual decrease in the ultimate shear stress Pm in the range of 20‒80 °C. It is shown that to improve the drying properties of the samples, the composition of pyrophyllite ‒ clay ‒ water is more homogeneous than the composition of clay ‒ water. Analysis of the Pm of the samples under the conditions of hot forming showed that it is not so much the dependence Pm = f(t) that takes on special importance, but the dependence Pm = f(W, t), where t ― the temperature; W ― the humidity.

Comparison of the effectiveness of preoperative Gabapentin with Celecoxib in reducing acute postoperative pain in abdominal hysterectomy: A randomized, double-blind controlled trial Objectives: To compare the effectiveness of Gabapentin with Celecoxib in reducing acute postoperative pain in abdominal hysterectomy. Material and Methods: A double-blind, randomized controlled trial in patients who were assessed for eligibility to enter the study at Rajavithi Hospital between November 2018 and July 2019. Ninety patients were randomly assigned to three arms (placebo, Gabapentin 600 mg, and Celecoxib 400 mg). Drug administration was given as preemptive analgesia two hours before surgery. The postoperative pain score was assessed on NRS at immediate, 4, 6, 8,12, 24 hours and at discharge. Intravenous morphine was used to relieve postoperative pain on demand. Morphine requirement and adverse effects were recorded. Results: Patients in the Celecoxib group had significantly lower pain scores at immediate, 4, 6, 8,12, 24 hours, and at discharge time. However, there was no difference in the Gabapentin group after multivariate-adjustment. Celecoxib revealed a significantly reduced pain score and was superior to Gabapentin (95%CI -1.023 - -0.170, P < 0.006 * vs -0.650 - 0.102, p = 0.153). Preoperative analgesia Celecoxib significantly decreased total morphine consumption (95%CI 0.078 - 0.160, p <0.001*). Conclusion: Preoperative Celecoxib 400 mg significantly decreased acute postoperative pain. Celecoxib was more efficient than Gabapentin in reducing pain in terms of earlier onset and longer duration, and decreasing total morphine consumption. Adverse effects were not significantly different.

Plants produce a variety of compounds with diverse structure and abundance that play an important role in the development, growth and response to the environment. Metabolomics involves studies of a great number of metabolites, which are small molecules present in biological systems.Metabolite profiles can be obtained from several samples by LC/MS (liquid chromatography coupled to mass spectrometry). However, the large number of ions detected for each run from different treatments and replicates require automatic processing for both spectra (metabolite identification and quantification) and global analysis of the metabolome. Thus, this protocol describes in detail, step-by-step, the comparison of the metabolite profiles from LC/MS data for determination of dysregulated pathways, as well as for Exploratory Statistical and Functional Enrichment Analyzes. .

Ezúttal 734 edényes taxon előfordulási adatait közöljük az ország szinte egész területéről (mintegy 222 fló­ra­tér­képezési kvadrátból), de legnagyobb számban az Északi-középhegységből és a Duna–Tisza-köze északi ré­széből, valamint a Hanság déli pereméről, a Maros-mentéről és a Hortobágyról. Összesen 1632 új adattal járulunk hozzá az Atlaszhoz. Az adatok között számos ritkább, vagy lokálisan jelentős őshonos, esetleg bi­zonytalan őshonosságú taxont találunk, sok esetben számolunk be terjedő idegenhonos fajok új le­lő­he­lye­i­ről, egyes esetekben pedig túlélő idegenhonosokról. Emellett országosan elterjedt fajok esetében is kö­zöl­jük az Atlasz térképein korábban nem jelölt lelőhelyeket.

Labeling System with EEG, EMG, and IMU for Visual Training of Autonomous Vehicles
Authors: SEÇKİN Ahmet Çağdaş
Published: October 2019

Autonomous vehicles are tools that make decisions and take decisions by perceiving their environment. Today, autonomous vehicles are also used in traffic in some countries. Various types of cameras, laser radars (LIDAR), sonar distance sensors, etc. are used for environmental detection in autonomous vehicles. After the environment is perceived, the collected data is taught to the vehicle with the help of machine learning methods and the vehicle reaches the target by following the traffic rules. At the point of traffic rules, the biggest task belongs to image-based systems. However, ideal traffic conditions and environmental conditions are not always provided. It is important to identify situations that may present a danger to autonomous vehicles. When the literature is examined, no visual data set or a scientific study with dangerous labeling has been found. In this study, it is aimed to design a data collection and labeling system to overcome this gap in the literature. In the system designed for the purpose, a system which automatically creates a video label from the physiological data of the driver (EEG ve EMG) and the inertia change data during human driving is designed. For this reason, firstly, the sensor signals were collected by experiments. In the time and frequency field, attributes were extracted by using the non-overlapping sliding window with 0.33 sec length. The input variables in the data set were reduced by PCA and classified by DT, RF and K-NN algorithms. According to the preliminary study findings, the K-NN method was the most successful algorithm among the algorithms tested with 0.922 accuracy.

Dialectical Thinking: Logics and Psychology
Authors: Veraksa N.E.
Published: October 2019

The article is devoted to the relation of logic and psychology of dialectical thinking. It provides three lines of understanding of dialectical thinking: dialectical thinking as a form of developing content, based on the resolution of oppositions; dialectical thinking as postformal stage of intelligence; dialectical thinking as a form of operating relationships of the opposites. Each approach has its own applications to the organization of educational practice. The first approach is presented by the works of E.V. Il'enkov, B.M. Kedrov, P.V. Kopnin and other authors. On a meaningful understanding of dialectics V.V. Davydov developed his methodology of developmental learning. The second approach in the study of dialectical thinking was largely shaped by J.Piaget’s operational concept of the intellect. K. Riegel argued that the development of thinking cannot stop at the stage of formal operations. Later on, the subject develops a more complex form of cognition — dialectical thinking. Representatives of the postformal understanding of dialectical thinking apply it in trainings for the development of professional thinking in adult subjects as well as in psychotherapy. In Russian psychology it has been shown that dialectical thinking acts as the individual’s independent ability to operate with opposites that can be developed starting from preschool age.

The current research studies the problems connected with interrelation between religiosity and intergroup hostility (or prejudice). We hypothesized and verified the connection between identification with religious group and ethno-national attitudes. Diagnostic methods measuring in-group religious identification, ethno-national attitudes, subjective categories of social consolidation and agreement with patriotic ideologems (by C.W. Leach, E. R. Agadullina, A.V. Lovakov, L. M. Drobizheva, O.E. Khukhlaev, N.V. Tkachenko, I.M. Kuznetsov, V.D. Shapiro) were used on the sample of 1032 participants (ages from 17 to 22 years), belonging to one of three religions: Buddhism (Kalmyks), Islam (Chechens) or Orthodoxy (Russians). The regression analysis provided statistically significant connections (p<0.05) of in-group religious identification and patriotic ethno-national attitudes of young people, regardless of their religion. Moreover among Russian Buddhist, Muslim and Orthodox youths the identification with the religious group is not revealed as a predictor of intergroup hostility. The study results extend the scientific understanding of the relationship between religious identity and intergroup relations.
Relationship between Volitional Regulation and Ethnic Identity
Authors: Shlyapnikov V.N.
Published: October 2019

The paper analyses the ethnocultural factors of volitional regulation from the cultural-historical perspective. A hypothesis is put forward about the relationship between the specifics of volitional regulation and national self-consciousness of the individual. The aim of the work is to study the relationship between ethnic identity and features of volitional regulation among representatives of various ethnic groups (Russians, Komis, Tuvans, Kabardians, Mari, Koreans). A total of 600 people aged 18 to 30 years took part in the study (the samples were gender balanced). To evaluate the individual characteristics of volitional regulation in the respondents, the following techniques were used: the Action Control Scale by J. Kuhl; the "Questionnaire for revealing the expression of self-control in the emotional sphere, activity and behavior"; the technique for self-assessment of volitional qualities; the Purpose in Life Test. The features of ethnic identity were evaluated using the “Types of Ethnic Identity” technique (by S.V. Ryzhova, G.U. Soldatova). The study revealed significant positive correlations between the intensity of volitional self-control and the overall score of volitional self-esteem and positive ethnicity in groups where nationality occupies an important place in the structure of the subject's self-consciousness (Tuvans, Koreans, Kabardians).
Digital Media as a New Means of Mediation (Part One)
Authors: Rubtsova O.V.
Published: October 2019

The article begins the cycle “Digital media as a new means of mediation”. “Digitalization” is interpreted as a challenge to contemporary psychology in general and cultural-historical theory in particular. The results of a theoretical and methodological analysis of the possibilities of regarding digital media as a new phenomenon, combining components of a sign and of a tool, are presented. Possible directions of research on various aspects of applying digital media in the framework of the cultural-historical concept are discussed. It is argued, that perceiving digital media as a new means of mediation opens a wide range of possibilities for investigating development of higher mental functions in digital society. One of the further steps of research consists in demonstrating, how traditional types of activity (e.g. reading, writing, play and communication) are transformed in digital contexts and what effects it can have on such functions as attention, memory, will and thinking.
Types of Catharsis in the Perception of Paintings
Authors: Ermolaeva M.V. , Lubovsky D.
Published: October 2019

The article analyzes the functions and structure of psychological catharsis as a cultural means of meaning-making. Basing on eudemonistic understanding of catharsis, the authors show its meaning-making action. In the structure of catharsis, there are phases of excitement (pathos), concentration (‘merging’ with the main character), and transcendence (‘reaching beyond one’s limitations’) which, through personal reflection, concludes with the individual’s ‘return to oneself’, transformed through the encounter with the work of art. The authors consider catharsis as an event that encourages action and creates the space of opportunities for it; basing on the research of art historians, the authors describe two kinds of catharsis (in the perception of Caravaggio’s and Rembrandt’s works). The authors identify psychotechnical means of interrupting catharsis at the moment of emotional extremum (in the works of Caravaggio) and the conditions for completing the reflective catharsis with the ‘return to one’s transformed self’ (using the paintings of Rembrandt as an example). The paper concludes with an outline of further prospects of exploring catharsis as a cultural means of meaning-making.
The Scientific Targets: the Myocardium, the Vasculature and the Body’s Response to Heart Failure
Authors: Vidal-Pérez Rafael , Jankowska Ewa
Published: October 2019

Heart failure (HF) is a common but complex clinical syndrome associated with a reduced ability of a heart to pump and/or fill with blood.    We now appreciate the more complex picture involving metabolic derangements, changes in foetal gene expression and abnormalities in the periphery as forming part of the HF syndrome. Therapeutic targets include the failing myocardium, the vasculature and peripheral mechanisms. The pathophysiology of HF is currently being intensively investigated, with the identification  of  new  relevant  mechanisms, some of them emerging as potential therapeutic targets.
Vasopressin Receptor Antagonists (Vaptans) in Heart Failure
Authors: Lipiec Piotr , Metra Marco
Published: October 2019

Arginine vasopressin (a peptide neuroendocrine hormone) levels are elevated in patients with HF. Acting through 3 receptor subtypes, it can cause vasoconstriction and cardiac remodelling (receptors V1a), adrenocorticotropic hormone release (receptors V1b) and water reabsorption (receptors V2), thereby increasing preload and afterload. Vasopressin-receptor antagonists (vaptans), induce hypotonic diuresis and have been proposed as a treatment option for hyponatraemia, a known complication of HF. Three vaptans have been so tested; tolvaptan, conivaptan and lixivaptan, and  two (tolvaptan and conivaptan) have been approved for clinical use in hyponatraemia (in the USA). The EVEREST trial studied tolvaptan in over 4100 patients hospitalized with an exacerbation of chronic HF with reduced LVEF. No effect was seen on long-term mortality or HF-related morbidity, but there was greater weight loss and better dyspnoea and oedema relief over the short-term.  Similar results were seen in the AQUAMARINE study. The 2016 European HF guidelines, therefore gave the limited recommendation: “Tolvaptan may be used to treat patients with volume overload and resistant hyponatraemia”. Despite targeting  an attractive  therapeutic target,  vasopressin receptor antagonists (vaptans) have to date played only a minor role in our management of HF.
Phosphodiesterase Inhibitors
Authors: Plácido Rui , Lainscak Mitja
Published: October 2019

Phosphodiesterases (PDEs) comprise a superfamily with 11 subfamilies. Within these families, more than 40 isoforms are expressed. Phosphodiesterase-3 inhibitors (PDE3i) are used as inotrope/vasodilators for acute heart failure (HF), and PDE5i for pulmonary hypertension and erectile dysfunction. Despite being studied for chronic HF, none of the PDEis have been presently approved for such an indication itself. The PDE3is milrinone (the PROMISE trial and OPTIME-CHF), raised safety concerns.   Although low-dose intravenous milrinone with a beta-blocker is till proposed by some. Enoximone failed to show significant benefits in patients with severe chronic HF in a series of phase 3 clinical trials (ESSENTIAL 1, ESSENTIAL II, EMOTE, EMPOWER).   Of the PDE5is, Sildenafil is the most extensively investigated, with proven efficacy in treating erectile dysfunction and pulmonary arterial hypertension, but it has only been tested in relatively small trials in the field of HFrEF, but shows some promise in HFpEF and in pulmonary hypertension complicating HF.  Elucidation of the potential clinical role of PDEis on across the spectrum of HF phenotypes will require more definitive evidence from large-scale clinical trials.
