title: Potassium chloride: impacts on soil microbial activity and nitrogen mineralization

description: ABSTRACT: Potassium chloride is the most widely used potassium source worldwide, and due to its continuous use, the accumulation of its salts in the soil and in plants is becoming more common. Excess available ions can cause a series of physiological disturbances in organisms and can become a biocide in the soil. The objective of this study was to evaluate the effects of the application of KCl and banana crop residues on soil chloride content, microbial activity, and soil ammonification. The experiment utilized a completely randomized 2 × 4 factorial design with four replicates. Treatments were as follows: two doses of vegetal residue (200 and 400 mg dm-3) × four doses of KCl (0, 167, 334, and 668 mg dm-3 of KCl) and a control (untreated soil). The CO2 emission, ammonium (N-NH4 +) and soil chloride (Cl-) content, and mineralization/immobilization rates of the soils in each treatment were measured 4, 45, and 130 days after incubation (dai). Higher KCl dosages reduced soil microbial activity at 4 dai, regardless of the residue dosage. Microbial activity was reduced at 130 dai in all treatments when compared to the initial period. Higher dosages of banana crop residues increased the Cl- content of the soil and promoted the immobilization of N-NH4 +. We concluded that dosages of KCl (above 400 mg dm-3), when applied to soils that already contain crop residues, reduce microbial activity and mineralization of N in the soil.

title: Potential of aqueous extracts of basidiomycetes to control root-knot nematodes on lettuce

description: ABSTRACT The root-knot nematode (Meloidogyne incognita) is one of the main pests of lettuce due to the crop’s high susceptibility, unavailability of registered nematicides and lack of resistant cultivars. The aim of this study was to evaluate the potential of aqueous extracts of ten basidiomycete fungi for root-knot nematode control (in vitro and in vivo) on lettuce. The aqueous extracts of these fungi were initially evaluated in vitro in relation to their nematostatic and nematicidal activity. All extracts inhibited the hatching of second-stage juveniles of nematodes. The extracts that provided the highest mortality index (Pleurotus ostreatus, P. citrinopileatus, P. pulmonarius and Boletus sp.) were applied in pots containing autoclaved and infested soil with root-knot nematode. After 24 h, one lettuce seedling (cv. Regina) per pot was transplanted using soil treated with distilled water as control. After 50 days, we observed that soil treated with fungal extracts reduced, approximately, 70% of nematode reproduction. Plants treated with extracts obtained higher fresh mass and extracts of Boletus sp. and P. pulmonarius reduced damages to roots, being considered as potential bio-controllers of this nematode.

title: Evaluation of quality of the family health strategy in the Federal District

description: ABSTRACT Aim: To evaluate quality of the Family Health Strategy (FHS) in the National Program for Improving Access and Quality of Primary Care in the Federal District (FD) from the perspective of users. Methods: Evaluative research carried out in 25 basic health units of the Federal District through a validated questionnaire assessing the following dimensions: access, gateway, bond, service range, coordination, family focus, community orientation, and health professionals. Results: Service provision, qualification of professionals, quality of professional-user relationship, and continuity of care were the best evaluated dimensions, while family approach, community approach, and access were the worst. Access to the FHS was found to be compromised, besides failing to establish itself as gateway to the FD health system. Conclusion: When they can access the local system, FD users do enjoy several services, but access is still a barrier, mainly because the very system is not prepared to meet users’ needs/preferences. The dimensions regarding family focus and community orientation are precarious, which reveals the need for reflection on the care model adopted in the Federal District.

title: Composition and ecology of a snake assemblage in an upland forest from Central Amazonia

description: Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Experimental Farm area of the Federal University of Amazonas in Manaus, Brazil. Data collection was carried out in 24 standardized plots. Each plot was sampled four times between July 2015 and April 2017 by active search method. We recorded 83 individuals from 29 species belonging to six families. The richness in the study area corresponded to 78% of the snake species and 100% of the families previously recorded for Manaus. As observed in other localities, the most abundant species was the Amazonian lancehead (Bothrops atrox). Multiple linear regression models did not detect any effect of environmental variables on species richness and abundance of individuals. However, quadratic polynomial regression models revealed that intermediate canopy opening percentages positively influence the richness and abundance of snakes. It is possible that the result is related to a tradeoff between the thermoregulation behavior of these animals and to their susceptibility to predation.

title: Consumption attributes and preferences on medicinal and aromatic plants: a consumer segmentation analysis

description: ABSTRACT: In recent years, increasing interest in natural and traditional plants, which are an integral part of rural life, has been observed because of health concerns and new social trends. In this regard, medicinal and aromatic plants (MAPs) are becoming more popular among consumers. The purpose of this research is to investigate consumers’ attitudes and behaviors toward MAPs in order to identify possible distinct consumer group and examine its potential linkage to the characteristics of the consumers’ demographic and socio-economic status. To detect the perceived differences among consumers, the principal component and k-means cluster analysis were performed using the data from a face-to-face survey (n=420) conducted in five major cities in the Mediterranean region of Turkey. The analysis allows segmenting the market into three homogenous clusters that have distinctive behavioral, attitudinal, and socio-demographic profiles. This segmentation is particularly effective for the dynamics and further expansion of the MAP sector as an important source for rural life.

title: Potential impact of small hydroelectric power plants on river biota: a case study on macroinvertebrates associated to basaltic knickzones

description: Abstract Small hydroelectric power plants (SHP) have been considered as an alternative for the generation of electricity with reduced environmental impacts. Nevertheless, no studies have addressed changes in a particular kind of river macrohabitat commonly affected by SHPs, the knickzones. This study aimed to assess the impact of a SHP construction on the aquatic macroinvertebrate fauna associated with two basaltic knickzones located in Sapucaí-Mirim River, Southeast Brazil. The first, considered as a functional knickzone, follows the natural dynamics of the river flow and preserves the original rock substrate. The second, considered as non-functional knickzone, was permanently flooded after the SHP construction and the consolidated rock substrate was changed by fine sediment. Sampling was carried out in two seasonal periods and the data were analysed through multivariate analysis. It was observed differences in composition and structure of the macroinvertebrates community between the knickzones and periods. The functional knickzone exhibited a much higher richness, 72 taxa compared to 44 in the non-functional, as well as a large number of exclusive taxa (38, being only nine exclusive to the non-functional). Diversity, equitability and density mean values were also higher in the functional knickzone. The limnological parameters varied significantly between dry and rainy seasons but not between the distinct knickzones. This kind of macrohabitats and its potential role for the rivers biodiversity is practically unknown. In the scenery of fast SHP expansion, further studies and protection measures are necessary.

title: Sepsis: evolving concepts and challenges

description: Sepsis remains a major cause of morbidity and mortality worldwide, with increased burden in low- and middle-resource settings. The role of the inflammatory response in the pathogenesis of the syndrome has supported the modern concept of sepsis. Nevertheless, a definition of sepsis and the criteria for its recognition is a continuous process, which reflects the growing knowledge of its mechanisms and the success and failure of diagnostic and therapeutic interventions. Here we review the evolving concepts of sepsis, from the “systemic inflammatory response syndrome triggered by infection” (Sepsis-1) to “a severe, potentially fatal, organic dysfunction caused by an inadequate or dysregulated host response to infection” (Sepsis-3). We focused in the pathophysiology behind the concept and the criteria for recognition and diagnosis of sepsis. A major challenge in evaluating the host response in sepsis is to characterize what is protective and what is harmful, and we discuss that, at least in part, the apparent dysregulated host response may be an effort to adapt to a hostile environment. The new criteria for recognition and diagnosis of sepsis were derived from robust databases, restricted, however, to developed countries. Since then, the criteria have been supported in different clinical settings and in different economic and epidemiological contexts, but still raise discussion regarding their use for the identification versus the prognostication of the septic patient. Clinicians should not be restricted to definition criteria when evaluating patients with infection and should wisely use the broad array of information obtained by rigorous clinical observation.

title: Antimicrobial susceptibility and virulence-associated genes in Campylobacter isolates from milk and wastewater in Hatay, Turkey

description: ABSTRACT: Campylobacter is one of the most common causes of bacterial foodborne diseases throughout the world. This study was conducted to determine the prevalence, antimicrobial resistance and virulence of Campylobacter isolates of raw cow’s milk and cattle slaughterhouse wastewater samples in Hatay, Turkey. A total of 114 raw milk and 78 wastewater samples were analyzed for the identification of C. jejuni, C. coli, and C. lari by multiplex PCR. The overall prevalence of Campylobacter was found to be 7.2%, of these isolates, 85.7% were identified as C. jejuni and 14.2% as C. coli, but C. lari was not detected in the study. The cdtA and cadF genes were present in 66.6% and 41.6% of C. jejuni isolates tested, respectively, but wlaN gene was not found in any of the isolates. Results of antimicrobial resistance analysis showed that 71.4% of the isolates were resistant to erythromycin, 64.2% to tetracycline, and 57.1% to ciprofloxacin. Overall, 8 of 14 Campylobacter isolates (57.1%) showed a multidrug resistance.

title: Vowel harmony and vowel-to-vowel coarticulation in two varieties of Brazilian Portuguese

description: ABSTRACT This work presents a study of Brazilian Portuguese pre-stressed vowels in penultimate, trisyllabic words with four informants, two from Campinas region (South-Eastern) and two from Recife (North-Eastern Brazil). A corpus of 58 familiar and unfamiliar words within carrier phrases evaluated the duration, F1 and F2 frequencies of pre-stressed and stressed vowels. The goal was to examine vowel harmony as a possible consequence of Vowel-to-Vowel anticipatory coarticulation. Results point to asymmetries of vowel harmony: its frequency is higher in familiar words; in Recife, the harmony with low and mid-low stressed vowels is more frequent; stressed /u/ triggers less harmony than the other stressed vowels and pre-stressed /e/ undergoes more harmony than pre-stressed /o/.

title: Apgar Scoring System in Brazil’s Live Births Records: Differences between Home and Hospital Births

description: Abstract Objective To promote informed choice for women and to compare home andhospital births in relation to the Apgar score. Methods Mother’s profile and Apgar score of naturally born infants (without forceps assistance) in Brazil between 2011 and 2015, in both settings-hospital or home-were collected from live birth records provided by the Informatics Department of the Unified Health System (DATASUS, in the Portuguese acronym). For the analysis, were included only data fromlow-riskdeliveries, including gestational time between 37 and 41weeks, singleton pregnancy, at least four visits of prenatal care, infants weighing between 2,500 g, and 4,000 g, mother age between 20-40 years old, and absence of congenital anomalies. Results Home birth infants presented significantly higher risk of 0-5 Apgar scores, both in 1 minute (6.4% versus 3%, odds ratio [OR] = 2.2, confidence interval [CI] IC 2-2.4) and in 5 minutes (4.8% versus0.4%,OR = 11.5,CI 10.5-12.7). Another findingis related to recovery estimateswhen from an initially bad 1-minute Apgar (&lt;6) to a subsequently better 5-minute Apgar (&gt; 6). In this scenario, home infants had poorer recovery, Apgar scorewas persistently &lt; 6 throughout the fifth minute in most cases (71% versus 10.7%, OR 20.4, CI 17-24.6). Conclusion The results show worse Apgar scores for babies born at home, compared with those born at the hospital setting. This is a pioneer and preliminary study that brings attention concerning differences in Apgar score related to home versus hospital place of birth in Brazil.
