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.

ABSTRACT

OBJECTIVES: to analyze and compare levels of stress and resilience in nurses before and after the assessment for maintenance of the Hospital Accreditation Certification.

METHODS: quantitative, observational, and longitudinal research, with 53 nurses from a philanthropic hospital, in the Rio Grande do Sul. Data collected in two stages, March, and July 2019, before the assessment visit and 60 days after, using the Bianchi Stress Scale and Resilience Scale. Descriptive and analytical statistics were employed.

RESULTS: the majority of participants showed an average stress level before and after the evaluation. The highest stress scores were related to Domains E (coordination of unit activities) and C (activities related to personnel administration). In both moments of the study, the participants had medium and high resilience.

CONCLUSIONS: managing people, processes, and assistance are stressful activities in the Accreditation process and increase the nurses’ stress levels.

ABSTRACT

This study aimed to evaluate the influence of bareback sexually explicit media (SEM) consumption on anal sex without a condom by men who have sex with men (MSM). To this end, a page was created on the Facebook® social network with a link that directed interested parties to a questionnaire. Cisgender men, aged 18 years and over, who had sex with other men in the last 12 months, were included. Data were collected in 2017 and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. A total of 2,248 MSM participated in the research, with a mean age of 24.4 years and a mean number of 3.9 partners in the last 30 days. Having multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), preferring movies with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), considering this practice a fetish and realizing it (ORa: 3.52; 95% CI 2.3-5.4), having casual partnerships (ORa: 1.8; 95% CI 1.5-1.9) and being aware of the partner’s negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the likelihood of engaging in anal sex without a condom. Thus, we found an association between the consumption of bareback SEM and sex without a condom among MSM.

ABSTRACT

Estimating the minimum streamflows in rivers is essential to solving problems related to water resources. In gauged watersheds, this task is relatively easy. However, the spatial and temporal insufficiency of gauged watercourses in Brazil makes researchers rely on the hydrological regionalization technique. This study’s objective was to compare different hierarchical and non-hierarchical clustering approaches for the delimitation of hydrologically homogeneous regions in the state of Rio Grande do Sul, Brazil, aiming to regionalize the minimum streamflow that is equaled or exceeded in 90% of the time (Q90). The methodological development for the regionalization of Q90 consisted of using regression analysis supported by multivariate statistics. With respect to independent variables for regionalization, this study considered the morphoclimatic attributes of 100 watersheds located in southern Brazil. The results of this study highlighted that: (i) the clustering techniques had the potential to define hydrologically homogeneous regions, in the context of Q90 in the Rio Grande do Sul State, mostly the Ward algorithm associated with the Manhattan distance; (ii) drainage area, perimeter, centroids X and Y, and mean annual total rainfall aggregated important information that increased the accuracy of the cluster; and (iii) the refined mathematical models provided excellent performance and can be used to estimate Q90 in ungauged rivers.

ABSTRACT

The scope of this study was to investigate the prevalence of sexual exploitation of homeless children and adolescents living on the streets, as well as characteristics associated with this outcome. In this cross-sectional investigation, carried out in the municipalities of Rio Grande and Porto Alegre-RS, data were collected through interviews, which were conducted by trained interviewers. The Respondent-Driven Sampling (RDS) strategy was adopted and statistical analyses were conducted using Poisson regression with robust adjustment of variance. The sample included 186 children and adolescents between 10 and 17 years of age, of which 8% reported having been subjected to sexual exploitation. Being 16 to 17 years old, having had forced sexual intercourse and not having bonds with school were characteristics independently associated with this outcome. It was observed that the lack of contact with school increased the probability 16-fold of having suffered sexual exploitation, being considered the main risk factor in this study. The proposition is that the inclusion and permanence of homeless children and adolescents living on the streets into schools might significantly reduce the risk of sexual exploitation of this population group.

ABSTRACT

PURPOSE: To evaluate the effect of pupil dilation on intraocular pressure in preterm and term newborns.

METHODS: This prospective study involved 55 eyes of 28 preterm infants and 38 eyes of 20 term infants. The infants were divided into two groups according to their gestational ages at birth as follows: preterm group, <37 weeks and term group, ≥37 weeks. Pupil dilation was attained with tropicamide 0.5% and phenylephrine 2.5%. Intraocular pressure measurements were performed with Icare PRO (Icare Finland Oy, Helsinki, Finland) before and after pupil dilation. A paired t test was used to compare the measurements before and after pupil dilation.

RESULTS: The mean intraocular pressure change was -1.04 ± 3.03 mmHg (6.20/-11.40 mmHg) in the preterm group and -0.39 ± 2.81 mmHg (4.60/-9.70 mmHg) in the term group. A statistically significant difference in intraocular pressure was observed only in the preterm group after pupil dilation (p=0.01).

CONCLUSION: An unexpected alteration in intraocular pressure in newborns may occur after pupil dilation, especially in preterm infants.

ABSTRACT

PURPOSE: To assess choroidal changes using enhanced depth imaging optical coherence tomography in coronavirus disease (COVID-19).

METHODS: Thirty-two patients with moderate COVID-19 and 34 healthy subjects were included in the study. Choroidal thickness was measured at 3 points as follows: at the subfovea, 1500 mm nasal to the fovea, and 1500 mm temporal to the fovea. The total choroidal area, luminal area, stromal area, and choroidal vascular index were measured with Image-J. All the measurements were performed during the disease and at 4 months after remission.

RESULTS: In the patient group, the subfoveal, nasal, and temporal choroidal thicknesses were decreased as compared with those in the controls, but without statistically significant differences (p=0.534, p=0.437, and p=0.077, respectively). The mean total choroidal, stromal, and luminal areas and choroidal vascular index were statistically significantly decreased in the patient group (p<0.001, p=0.001, p=0.001, and p=0.003; respectively). At 4 months after remission, the choroidal structural parameters and choroidal vascular index revealed statistically significant increases as compared with the baseline measurements in the patients with COVID-19 (all p<0.001 and p=0.047, respectively).

CONCLUSION: The choroidal vascular and stromal parameters showed significant transient decreases during the disease course of COVID-19.

ABSTRACT

While ensuring employment opportunities is critical for global progress and stability, workers are now subject to several disruptive trends, including automation, rapid changes in technology and skill requirements, and transitions to low-carbon energy production. Yet, these trends seem almost insignificant compared to labor impact of the COVID-19 pandemic. While much has been written about the pandemic’s short-term impacts, this study analyzes anticipated long-term impacts on the labor force of 2029 by comparing original 2029 labor projections to special COVID-adjusted projections recently published by the US Bureau of Labor Statistics. Results show that future demand for nearly every type of labor skill and knowledge will increase, while the nature of work shifts from physical to more cognitive activities. Of the nearly three million jobs projected to disappear by 2029 due to COVID, over 91% are among workers without a bachelor’s degree. Among workers with a degree demand shifts primarily from business-related degrees to computer and STEM degrees. Results further show that the socialness of labor, which is important for both innovation and productivity, increases in many more industries than it decreases. Finally, COVID will likely accelerate the adoption of teleworking and slightly decrease the rate of workforce automation. These impacts, combined with a shift to more cognitive worker activities, will likely impact the nature of workforce health and safety with less focus on physical injuries and more on illnesses related to sedentary lifestyles. Overall, results suggest that future workers will need to engage more often in training and skill acquisition, requiring life-long learning and skill maintenance strategies.

ABSTRACT

OBJECTIVE: to identify burnout and associated factors among nursing workers working in coping with COVID-19.

METHODS: a cross-sectional study, developed in four hospitals in a capital in southern Brazil. Sample (n=499) composed of nurses and nursing technicians/assistants, who answered an online form containing socio-occupational characterization and the Maslach Burnout Inventory. Descriptive and inferential statistical analysis was performed, including multiple comparison tests.

RESULTS: burnout was identified in 60 (12%) workers, with no significant difference between hospitals, but with a difference in dimensions between them. In the emotional exhaustion dimension, a higher proportion (52.9%) was found at a moderate level. Prevalence of high level of professional achievement of 95.4% was identified.

CONCLUSION: the presence of burnout was significantly prevalent among nurses and females. It reinforces the need to develop strategies to promote the health of nursing workers, providing improvement in health services and reduction of care and labor risks.

ABSTRACT

OBJECTIVE: The demand for treating degenerative lumbar spinal disease has been increasing, leading to increased utilization of medical resources. Thus, we need to understand how the budget of insurance is currently used. The objective of the present study is to overview the utilization of the National Health Insurance Service (NHIS) by providing the direct insured cost between patients receiving surgery and patients receiving nonsurgical treatment for degenerative lumbar disease.

METHODS: The NHIS-National Sample Cohort was utilized to select patients with lumbar disc herniation, spinal stenosis, spondylolisthesis or spondylolysis. A matched cohort study design was used to show direct medical costs of surgery (n = 2,698) and nonsurgical (n = 2,698) cohorts. Non-surgical treatment included medication, physiotherapy, injection, and chiropractic. The monthly costs of the surgery cohort and nonsurgical cohort were presented at initial treatment, posttreatment 1, 3, 6, 9, and 12 months and yearly thereafter for 10 years.

RESULTS: The characteristics and matching factors were well-balanced between the matched cohorts. Overall, surgery cohort spent $50.84/patient/month, while the nonsurgical cohort spent $29.34/patient/month (p<0.01). Initially, surgery treatment led to more charge to NHIS ($2,762) than nonsurgical treatment ($180.4) (p<0.01). Compared with the non-surgical cohort, the surgery cohort charged $33/month more for the first 3 months, charged less at 12 months, and charged approximately the same over the course of 10 years.

CONCLUSION: Surgical treatment initially led to more government reimbursement than nonsurgical treatment, but the charges during follow-up period were not different. The results of the present study should be interpreted in light of the costs of medical services, indirect costs, societal cost, quality of life and societal willingness to pay in each country. The monetary figures are implied to be actual economic costs but those in the reimbursement system instead reflect reimbursement charges from the government.
