Nursing diagnosis after hematopoietic stem cell transplant due to Fanconi anemia

ABSTRACT Objectives: to identify nursing diagnoses in patients who underwent hematopoietic stem-cell transplants due to Fanconi anemia, according to the NANDA-I taxonomy. Methods: exploratory study using a retrospective analysis of 85 records from patients who underwent hematopoietic stem-cell transplants due to Fanconi anemia, developed in a specialize transplant center in the South of Brazil. The results were analyzed using descriptive statistics. Results: 73 different diagnoses were found in 9 out of the 13 domains from the NANDA-I taxonomy. From these, 22 were in 50% or more of the patients investigated, and most of them are related to the domain Safety/Protection. Conclusions: it was possible to identify the nursing diagnosis in the patients who underwent hematopoietic stem cell transplants due to Fanconi anemia, contributing to design a plan for the care of these patients. The same was true for those with other syndromes of chromosomal instability that need to undergo this transplant.

Soil contamination by Ancylostoma spp. and Toxocara spp. eggs in elementary school playgrounds in the extreme south of Brazil

Millions of people worldwide, and especially schoolchildren, may be infected by geohelminths due to their exposure to a contaminated environment. The aim of this study was to evaluate soil contamination by Ancylostoma spp. and Toxocara spp. eggs in recreation areas at elementary schools in Pelotas, state of Rio Grande do Sul, Brazil. Sand samples were collected from 22 schools and were processed using the centrifugal flotation method. Helminth eggs with zoonotic potential were found in 12 out of the 22 schools (54.5%). Contamination by Ancylostoma spp. and Toxocara spp. was observed in 36.4% (8/22) and 27.3% (6/22) of the soil samples collected at these schools, respectively. These findings of eggs show that the school communities are exposed to risks of zoonotic transmission.

Nursery performance of potentially promising rootstocks for citriculture in the south of Brazil

ABSTRACT: Diversification of rootstock varieties, with consequent reduction in phytosanitary risks, has great importance to the sustainability of citrus cultivation in the south of Brazil. This study evaluated the performance of 42 rootstocks in the nursery phase to generate ‘Valencia Late’ sweet orange seedlings. Therefore, nucellar seedlings from the rootstocks under study were analyzed in relation to plant height, stem diameter, mortality rate and percentage of bud set after grafting. The experimental design was completely randomized with four replications of 20 sample units. Not adapted genotypes had high mortality rates, and the ones of both hybrids LCR x CTSW - 009 and LVK x LCR - 038 were 100% and 90%, respectively. Other 13 genotypes had mortality rates above 30%, and ‘Sunki’ mandarin was the female genitor of ten of them. ‘Swingle’ citrumelo was the rootstock with the highest development (plant height and stem diameter), associated with low mortality rate. In relation to the other rootstocks, the best results were the fast grafting diameter, associated with low mortality rate obtained by hybrids HTR - 053, LRF x (LCR x TR) - 005, CLEO x TRBN - 245, CLEO x TRSW - 287, and citrandarins ‘Indio’, ‘Riverside’ and ‘San Diego’, as well as Trifoliate orange and ‘Rangpur’ lime. In addition to Trifoliate orange, which is widely used in Rio Grande do Sul, these rootstocks have great potential in citriculture in the south of Brazil.

Water quality assessment of the Demetrio stream: an affluent of the Gravataí River in the South of Brazil

The Gravataí River basin, one of the main water sources of the metropolitan region of Porto Alegre, is among the ten most polluted rivers in Brazil. Water quality is monitored only through physico-chemical and microbiological parameters in Brazil, and in this context, considering the importance of the use of biomarkers in complementing the analysis of water, the present study aimed to evaluate the environmental quality of the main affluent of the Gravataí River, Demetrio stream, through physico-chemical, microbiological, and cytogenotoxic criteria, at the stream source (P1), whereas samples P2 and P3 were obtained from the upstream near the area with the highest urban density and the downstream near the meeting point with the Gravataí River, respectively. The results for copper concentration and color classified the Demetrio stream as Class 4 in general, that is, the water is suitable only for navigation and to landscape harmony. The main genotoxic alterations (micronuclei and nuclear buds) were observed in P2, in which were obtained the highest levels of copper, in addition to iron and manganese. Anthropic interventions were observed in P1 and P2; however, due to its low metal concentration, P3, near the Gravataí River, manifested an improvement in environmental quality.

Reasons assigned to suicide attempts: adolescents’ perceptions

ABSTRACT Objective: identify the reasons for attempting suicide from the perspective of adolescents. Methods: qualitative study conducted with ten adolescents who attempted suicide and were attending a Centro de Atenção Psicossocial Infanto-Juvenil located in a city in the south of Brazil. Semi-structured interviews were held in July 2020 using WhatsApp. Data were analyzed according to Minayo’s Content Thematic Analysis. Results: the adolescents’ reports listed the reasons that triggered suicide attempts, such as changes in the adolescents’ life cycle and violence, which led them to attempt suicide to solve problems. Final considerations: Data analysis revealed the reasons that triggered suicide attempts from the adolescents’ perspective and difficulties to cope with problems, probably explained by their lack of experience in dealing with frustrations and disappointments.

Population structure and genetic diversity in sweet cassava accessions from South of Brazil

Cassava (Manihot esculenta Crantz) is a crop of high socioeconomic importance for several tropical and subtropical regions of the world. It is mainly present in small cultivated areas that unintentionally guard a large part of the species' germplasm. The present work aimed to evaluate the population structure and genetic diversity of 156 traditional sweet cassava accessions from the Western of Paraná and Midwestern regions of Santa Catarina using 29 microsatellite molecular markers. All loci included were considered polymorphic, ranging from 3.00 to 7.00, with an average of 3.93 alleles per locus, and the average value of heterozygosity (Ho) was 0.6185. The polymorphism information content (PIC) presented an amplitude that varied from 0.4887 (GA134) to 0.7041 (GA131), with an average of 0.6130, while the genetic diversity ranged from 0.5688 (GA134) to 0.7424 (GA131), with an average of 0.6751. Analysis of the population structure based on the 29 microsatellite loci demonstrate that the accessions can be separated into two distinct subpopulations - in Santa Catarina and Paraná - with some mixtures observed according to Delta K = 2 groups. The ideal number of groups was found at K = 3, a level in which accessions from Santa Catarina were divided into two subpopulations and accessions from Paraná were grouped into a unique subpopulation. The genetic variability found among the traditional sweet cassava cultivars evaluated was considered wide, and the most dissimilar groups were mostly the accessions from Toledo and Santa Catarina states, constituting a source of genes for the sweet cassava breeding programs and for the development of new sweet cassava cultivars.

Prevalence of crack cocaine use and its associated factors in patients treated in a specialized outpatient service

Background Despite the advance in studies addressing the use of crack cocaine, knowledge about the characteristics of users that seek treatment in the different modalities of care for substance use disorders is important to plan the operationalization of these services. Objective To analyze the prevalence and factors associated with the use of crack cocaine in outpatients. Method Cross-sectional study consisting in the analysis of the medical records of outpatients of a chemical dependency clinic located in the south of Brazil from 1999 to 2015. The Fisher’s exact test and the Poisson regression model were used to analyze the data. Results Medical records from 1,253 patients were analyzed, and 1,196 (95.5%) of them contained information on the use of crack cocaine. Use of this substance was reported by 47% (95% CI [44, 50]) of the outpatients. The risk group was composed of adults aged 20-39 years, with no income, who had three or more children, did not consume alcohol or marijuana, had continuous family assistance, spontaneously looked for the service, and had already been hospitalized or assisted at a therapeutic community or psychosocial center. Conclusion There is great demand for the outpatient care of crack cocaine users. It is crucial that the risk factors guide treatment planning.
