title: Intercropping maize and cowpea cultivars: II. Dry grain yield

description: ABSTRACT There is interest in identifying the best maize and cowpea cultivars to be used in monocropped and intercropping systems for the production of dry grain. In order to meet this interest, two monocrops of cowpea (the traditional varieties, Corujinha and Sempre Verde) were evaluated with two monocrops of maize (the AG 1051 double hybrid and the AL Bandeirante variety) and four intercrops (combinations of the cowpea varieties and the maize cultivars). Under the intercropping systems, the maize and cowpea occupied alternating rows. A completely randomized block design with six replications was used. Grain growth and yield were higher in the AG 1051 hybrid than in the AL Bandeirante variety in both the monocropped and intercropping systems. For medium-sized maize grain, the growth and yield were higher in the monocrops than in the intercrops. It is unimportant which variety of cowpea, Corujinha or Sempre Verde, is used with each maize cultivar in the intercropping systems, as there was no interaction between the maize cultivars and the cowpea cultivars. In the monocropped systems, the grain yield of the Corujinha cultivar was greater than that of the Sempre Verde cultivar. Mean grain yield in the monocrops was greater than in the intercrops. Both cowpea cultivars showed better performance when intercropped with the AL Bandeirante maize cultivar than with the AG 1051 cultivar. The value of the land equivalent ratio was greater than 1.0 only for the combination of the AL Bandeirante variety of maize and the Sempre Verde variety of cowpea.

title: Germination of fungal pathogen spores in calcium, copper, manganese and zinc chelated with aminoacids

description: ABSTRACT Due to the environmental impact generated using fungicides, new alternatives for disease control have been arising, such as the use of nutrients that may act on the development of certain pathogens or decrease the host susceptibility to diseases. The objective of this work was to verify if chelates of calcium, copper, manganese and zinc inhibit the germination of Puccinia sorghi, Cercospora sp. and Exserohilum turcicum spores. Two experiments were carried out: the first with agar-water culture medium, where the treatments and spores were placed at the same moment and the second using corn leaves as substrate, where treatments were administered zero, one, two, three, four and five hours after the spores are sprayed. Calcium, copper, manganese and zinc products were used as treatments in the form of chelate 15%, 5%, 15% and 10%, fungicide (strobilurine and triazole, 20% azoxistrobin and 8% ciproconazole + triazole, 25% propiconazole) and distilled water. The spores were counted 24 hours after the application of the treatments. In the first experiment, chelates showed an average reduction of 39% in both germination of P. sorghi and Cercospora sp. spores. For the second assay, the same pathogens had a mean reduction of 52%, 59%, 77%, 87%, 81% and 64% for P. sorghi and 40%, 33%, 17%, 18%, 4% and 2% for Cercospora sp., both at zero, 1, 2, 3, 4 and 5 hours after treatment, respectively. E. turcicum had no inhibitory effect under treatments. The metal-chelates tested were fungitoxic to P. sorghi and Cercospora sp. spores.

title: Production and benefits in carrot and vegetable cowpea associations under green manuring and spatial arrangements

description: ABSTRACT The use of a cropping system that provides producers with better land use, higher productivity per unit area, greater diversification in production, and, consequently, agro-economic advantages, is the choice of many vegetable producers. To meet the demands of these producers, experiments were conducted under field conditions in a semi-arid environment to evaluate the production and agro-economic benefits of carrot x vegetable cowpea associations as a function of green manuring with biomass of Merremia aegyptia L., a spontaneous species from the Caatinga biome, in different spatial arrangements at two cropping years. The experimental design was a randomized complete block design with treatments arranged in a 4 x 3 factorial scheme, with four replications. The first studied factor was the amounts of M. aegyptia biomass (20, 35, 50, and 65 t ha-1 on a dry basis), while the second factor was the spatial planting arrangements (2:2, 3:3, and 4:4), corresponding to rows of carrot alternated with rows of vegetable cowpea. The production optimization of the carrot and cowpea cultures was achieved with the incorporation of the M. aegyptia biomass amounts of 32.69 and 50.17 t ha-1, respectively, and agro-economic optimization of the entire intercropping system was obtained at a biomass amount of 34.66 t ha-1. The spatial planting arrangement of 2:2 resulted in the greatest agro-economic efficiency of the crop association.

title: Growth and physiological quality in clonal seedlings of Robusta coffee

description: ABSTRACT The intrinsic characteristics of the vegetative propagule may influence the rooting speed and shoot growth, as well as the final physiological quality of clonal seedlings of Coffea canephora. The aim of this study was to evaluate the growth and physiological quality of ‘Robusta’ coffee seedlings produced from propagules (stem cuttings) with different cutting ages. The study was conducted in a greenhouse, in the district of Ouro Preto do Oeste, in Rondônia, Brazil (10˚45’43” S and 62˚15’10” W). The ages of the cuttings were 30, 60, 90, 120 and 150 days, corresponding to five positions on the secondary orthotropic stem (sprout), from the apex to the base. Dry matter accumulation, and relative and absolute growth rates were evaluated for 188 days after cutting, as well as the vegetative characteristics of the seedlings at 125 days after cutting. It appears that growth can be divided into three phases: 1) Initial: slow growth, lasting approximately 83 days; 2) Intermediate: fast growth, lasting approximately 40 days; and 3) Final: slow growth, starting approximately 125 days after cutting. With physiological quality, although all the cuttings showed similar growth curves, those of 60, 90 and 120 days produced, 125 days after cutting, the best vegetative performance in the seedlings.

title: Nonlinear models to describe height and diameter of sugarcane RB92579 variety

description: ABSTRACT Brazil is the world’s largest sugarcane producer (Saccharum spp.), followed by India and China. In 2019, Brazil produced 642.7 million tons of sugarcane, having collected 1.44 billion and 983.52 million dollars from sugar and ethanol exports, respectively. For crop management, it is important to monitor plant growth, duration of growth phases and point of physiological maturation. The aim of this study was to evaluate the fit of nonlinear Logistic, Gompertz, Brody and von Bertalanffy models to the height and diameter growth of ratoon cane stalk RB92579 variety, considering age in days. The parameters of models were estimated using R software routines, applying the least squares method and the iterative Gauss-Newton process. The adjustment of models was compared using the following evaluators: determination coefficient (R2), residual standard deviation (RSD) and corrected Akaike information criterion (AICc). In all models, parameters were significant by the t test at 1% level, except for the Brody model. When using the Shapiro-Wilk, Durbin-Watson and Breusch-Pagan tests, it was found that residues were normal, homoscedastic and independent at 1% significance level. All models fitted well to data, except for the Brody model for stalk height. Based on results, the Gompertz and Logistic models presented higher R2 values and lower RSD and AICc values; thus, it could be concluded that these models are suitable to describe the height and diameter of sugarcane RB92579 cultivar, respectively.

title: COVID-19 information exposure in digital media and implications for employees in the health care sector: findings from an online survey

description: ABSTRACT Objective: To estimate coronavirus disease 2019-related information consumption and related implications for health care professionals (medical and nonmedical personnel) during the pandemic. Methods: A cross-sectional on-line survey was distributed to employees of a major health care institution located in São Paulo, Brazil between April 3 and April 10, 2020. Data were analyzed using descriptive statistics. Results: The sample comprised 2,646 respondents. Most participants (44.4%) reported excessive or almost excessive access to information about the novel coronavirus and 67.6% reported having increased their average time spent on social media. When asked how frequently they consider it was easy to determine the reliability of information, “sometimes” corresponded to 43.2% of the answers in contrast to 14.6% responding “always”. Answers related to potential signs of information overload associated with the pandemic indicated that 31% of respondents felt stressed by the amount of information they had to keep up with almost every day or always. Overall, 80.0% of respondents reported having experienced at least one of the following symptoms: headache, eye twitching, restlessness or sleeping difficulty. The frequency of symptoms was higher among participants with a more negative information processing style regarding when dealing with large volumes of information relative to those with a positive information processing style. Likewise, symptoms were more frequently reported by participants who had increased their social media access relative to those reporting reduced access during the pandemic. Conclusion: Our survey provides a description of how health professionals consume COVID-19 related information during the pandemic, and suggests that excessive information exposure and high processing demands may impose psychological distress and affect mental health.

title: Multiple myeloma: five-year experience at a University Hospital

description: Objective: To present a descriptive analysis of patients diagnosed with multiple myeloma, correlating it with mortality. Methods: A retrospective study that analyzed consecutive patients diagnosed with multiple myeloma under follow-up at the Faculdade de Medicina do ABC from 2006 to 2010. Results: The median age was 58.5 years. Anemia was observed upon diagnosis in 87% of patients, hypercalcemia in 38%, and creatinine levels higher than 2 mg/dL in 19%. M protein was detected in 85.7%. The five-year survival rate was 74.6%. Multivariate analysis showed statistical significance for Durie-Salmon staging (p = 0.037). The International Staging System and immunoglobulin type did not correlate significantly with survival of the group. Conclusion: This set of cases from a tertiary public healthcare service reflect the approach of multiple myeloma in a predominantly young population with advanced clinical staging, with results comparable to those of the literature.

title: Allogeneic hematopoietic stem cell transplantation in children with primary immunodeficiencies: Hospital Israelita Albert Einstein experience

description: Objective: To report the experience of a tertiary care hospital with allogeneic hematopoietic stem cell transplantation in children with primary immunodeficiencies. Methods: Seven pediatric patients with primary immunodeficiencies (severe combined immunodeficiency: n = 2; combined immunodeficiency: n = 1; chronic granulomatous disease: n = 1; hyper-IgM syndrome: n = 2; and IPEX syndrome: n = 1) who underwent eight hematopoietic stem cell transplants in a single center, from 2007 to 2010, were studied. Results: Two patients received transplants from HLA-identical siblings; the other six transplants were done with unrelated donors (bone marrow: n = 1; cord blood: n = 5). All patients had pre-existing infections before hematopoietic stem cell transplants. One patient received only anti-thymocyte globulin prior to transplant, three transplants were done with reduced intensity conditioning regimens and four transplants were done after myeloablative therapy. Two patients were not evaluated for engraftment due to early death. Three patients engrafted, two had primary graft failure and one received a second transplant with posterior engraftment. Two patients died of regimen related toxicity (hepatic sinusoidal obstruction syndrome); one patient died of progressive respiratory failure due to Parainfluenza infection present prior to transplant. Four patients are alive and well from 60 days to 14 months after transplant. Conclusion: Patients’ status prior to transplant is the most important risk factor on the outcome of hematopoietic stem cell transplants in the treatment of these diseases. Early diagnosis and the possibility of a faster referral of these patients for treatment in reference centers may substantially improve their survival and quality of life.

title: Impact of screening and monitoring of capillary blood glucose in the detection of hyperglycemia and hypoglycemia in non-critical inpatients

description: ABSTRACT Objective: To evaluate the impact of screening hyper and hypoglycemia measured by capillary glycemia and standard monitorization of hyperglycemic patients hospitalized in regular care units of Hospital Israelita Albert Einstein. Methods: The capillary glycemia was measured by the Precision PCx (Abbott) glucosimeter, using the PrecisionWeb (Abbott) software. The detection of hyper and hypoglycemia during the months of May/June were compared to those of March/April in 2009 and to the frequency of the diagnosis of diabetes in 2007. Results: There was an increase in the glycemia screening from 27.7 to 77.5% of hospitalized patients (p &lt; 0.001), of hyperglycemia detection (from 9.3 to 12.2%; p &lt; 0.001) and of hypoglycemia (from 1.5 to 3.3%; p &lt; 0.001) during the months of May/June 2009. According to this action 14 patients for each additional case of hyperglycemia and 26 cases for each case of hypoglycemia were identified. The detection of hyperglycemia was significantly higher (p &lt; 0.001) than the frequency of registered diagnosis related do diabetes in the year of 2007. Conclusions: the adoption of an institutional program of glycemia monitorization improves the detection of hyper and hypoglycemia and glycemia control in hospitalized patients in regular care units.

title: Expression of p53, p16 and Ki67 proteins in ductal adenocarcinoma of the pancreatic head and their relation with survival and cell differentiation

description: ABSTRACT Objective: To determine the expression of p53, p16 and Ki-67 and its relevance in survival and cell differentiation. Methods: Fifteen duodenopancreatectomized patients were included. Immunohistochemical expression of p53, p16 and Ki-67 was determined in paraffin embedded tumor blocks. The relation of these expressions with different variables was studied. Results: Ninety-three per cent of tumors showed expression of p53 and p16. Ki-67 was expressed in 86.66% of tumors (labeling index – LI 11.91 ± 9.47). The presence of combined alterations was not related to significant differences in tumor type, stage or survival; similar results were obtained analyzing isolated expressions. When groups of p16 and Ki-67 expressions where created, the median survival was not significant. However, there was a slightly better survival in patients with focal expression of p16 (median survival 20.75 versus 14.34), when compared to patients with diffuse expression. Conclusion: The overexpression of p53, p16 and Ki-67 was not related to survival or tumor grade, when comparing isolated or combined expressions.

title: Congenital malformations in newborns of alcoholic mothers

description: ABSTRACT Objective: To identify the presence of fetal alcohol syndrome, other alcohol-related congenital defects, and/or neurodevelopment disorders in newborns of mothers who consumed alcohol during gestation. Methods: In a public maternity in the city of São Paulo, 1,964 puerperal women were interviewed and 654 had consumed alcohol at some point during gestation. The newborns were clinically and laboratorially examined in order to identify the occurrence of fetal alcohol syndrome, congenital defects or neurodevelopment disorders related to alcohol. Results: Three children were found with fetal alcohol syndrome (1.5/1,000 live births), 6 with congenital defects related to alcohol (3.0/1,000 live births), and 67 with developmental disorders related to alcohol (34.1/1,000 live births). The congenital malformations found in these children were thin or absent corpus callosum, brain cyst, asymmetry of the cerebral ventricles, meningomyelocele, cleft lip, anteverted nose, low-set ears, megaureter, hydronephrosis, polydactyly, congenital clubfoot, aphalangia of the toes, cryptorchidism, and hypospadia. conclusion: Newborns of mothers who consumed alcohol may have congenital malformations of various organs and systems, and early diagnosis is fundamental for a probable and occasional more effective resolution and progress.

title: Frequency of peri-intraventricular hemorrhage and its associated factors in premature newborns

description: ABSTRACT Objective: To identify the frequency of intracranial hemorrhage and its associated factors in premature newborns. Methods: A cross-sectional study based on a survey of medical records of premature neonates submitted to transfontanellar ultrasound at a hospital located in a southern neighborhood of the city of São Paulo, in 2007. Results: A 50% rate of intracranial hemorrhage was found among premature newborns submitted to transfontanellar ultrasound, and 15.35% among all premature babies born in this hospital in 2007. The statistically significant factors associated to intracranial hemorrhage were gestational age less than 32 weeks, absence of prenatal care, invasive mechanical ventilation, infection, blood transfusion, hyaline membrane disease, hyponatremia and hyperglycemia. Conclusions: The frequency of peri-intraventricular hemorrhage was 50% in patients at risk and 15.35% among all premature babies; the associated factors were gestational age less than 32 weeks, absence of prenatal care, need of invasive mechanical ventilation, infection, blood transfusion, hyaline membrane disease, hyponatremia and hyperglycemia.

title: Denver II: evaluation of the development of children treated in the outpatient clinic of Project Einstein in the Community of Paraisópolis

description: ABSTRACT Objectives: To evaluate the neuropsychomotor development of children treated in an outpatient clinic, using the Denver Developmental Screening Test II (DDST-R). Methods: This was an exploratory descriptive research using a quantitative approach, conducted in the outpatient clinic of the Project Einstein in the Community of Paraisopolis (PECP), São Paulo, Brazil. The sample consisted of 35 children, from birth to 6 years of age, most of them from 1 to 3 years old (19; 54.3%). They underwent the Denver II Test, which assesses four neuropsychomotor development areas: gross motor, fine motor adaptive, language and personal-social. Results: Most of the children (24, 68.6%) had test results compatible with normal development, while 10 (28.6%) had a “risk” test and 1 (2.9%) was “untestable” due to refusal to carry out the proposed activities. As to the items evaluated in each area, 7 children (20%) showed a developmental “delay” (when the child does not perform the activity passed by more than 90% of the children of his/her age) and 18 (51%) required “attention” (when the child does not perform the activity passed by 75 to 90% of the children of his/her age), predominantly in the language area. Conclusions: Although most of the children (68.6%) presented normal development in the test, we point out that in the remaining children (31.4%), the number of items classified as “delay” or “attention”, and tests classified as “risk” or “untestable” suggest impairment in neuropsychomotor development. We underscore the importance of the routine administration of the DDST-R for an early detection of developmental disabilities and thus establish primary prevention programs.

title: Credit risk and technical efficiency in Brazilian credit unions

description: Abstract This study analyzed the relationship between credit risk and the efficiency of Brazilian credit unions in the period from 2008 to 2017. The two-stage data envelopment analysis model was used to obtain efficiency scores, with the analysis of a Tobit model in the second stage. Specialists were consulted for the construction and validation of efficiency scores, which is a contribution of this study in relation to the others. It was found that the higher the credit risk, the lower the efficiency scores, and that credit unions that manage to maintain their continuity in the market and diversify their products had higher efficiency scores, consequently generating greater benefits to their members. Additionally, cooperatives must pay attention to the number of service points and periods of economic recession. The increase in the number of service points reduces efficiency scores. When considering the period of Brazilian economic downturn, measured from 2015 to 2017, there was a negative impact on the average efficiency scores of the cooperatives. As a limitation, it is reported that the results are derived from the inputs and outputs selected from accounting and financial information, and it is suggested that new variables related to the social dimension of cooperatives be incorporated into other studies to assess the overall efficiency of Brazilian credit unions.
